YAZ is indicated for the prevention of pregnancy in women who elect to use an oral contraceptive.
Oral contraceptives are highly effective. Table II lists the typical unintended pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization and contraceptive implants and IUDs, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.
YAZ is also indicated for the treatment of symptoms of premenstrual dysphoric disorder (PMDD) in women who choose to use an oral contraceptive as their method of contraception. The effectiveness of YAZ for PMDD when used for more than three menstrual cycles has not been evaluated.
The essential features of PMDD according to the Diagnostic and Statistical Manual-4th edition (DSM-IV) include markedly depressed mood, anxiety or tension, affective lability, and persistent anger or irritability. Other features include decreased interest in usual activities, difficulty concentrating, lack of energy, change in appetite or sleep, and feeling out of control. Physical symptoms associated with PMDD include breast tenderness, headache, joint and muscle pain, bloating and weight gain. In this disorder, these symptoms occur regularly during the luteal phase and remit within a few days following onset of menses; the disturbance markedly interferes with work or school, or with usual social activities and relationships with others. Diagnosis is made by healthcare providers according to DSM-IV criteria, with symptomatology assessed prospectively over at least two menstrual cycles. In making the diagnosis, care should be taken to rule out other cyclical mood disorders. YAZ has not been evaluated for the treatment of premenstrual syndrome (PMS).
YAZ is indicated for the treatment of moderate acne vulgaris in women at least 14 years of age, who have no known contraindications to oral contraceptive therapy and have achieved menar-che. YAZ should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control.

In the primary contraceptive efficacy study of YAZ (3 mg DRSP/ 0.02 mg EE) of up to 1 year duration, 1,027 subjects were enrolled and completed 11,480 28-day cycles of use. The age range was 17 to 36 years. The racial demographic was: 87.8% Caucasian, 4.6% Hispanic, 4.3% Black, 1.2% Asian, and 2.1% other. Women with a BMI greater than 35 were excluded from the trial. The pregnancy rate (Pearl Index) was 1.41 per 100 woman-years of use based on 12 pregnancies that occurred after the onset of treatment and within 14 days after the last dose of YAZ in women 35 years of age or younger during cycles in which no other form of contraception was used.
Two multicenter, double-blind, randomized, placebo-controlled studies were conducted to evaluate the effectiveness of YAZ in treating the symptoms of PMDD. Women aged 18-42 who met DSM-IV criteria for PMDD, confirmed by prospective daily ratings of their symptoms, were enrolled. Both studies measured the treatment effect of YAZ using the Daily Record of Severity of Problems scale, a patient-rated instrument that assesses the symptoms that constitute the DSM-IV diagnostic criteria. The primary study was a parallel group design that included 384 evaluable reproductive-aged women with PMDD who were randomly assigned to receive YAZ or placebo treatment for 3 menstrual cycles. The supportive study, a crossover design, was terminated prematurely prior to achieving recruitment goals due to enrollment difficulties. A total of 64 women of reproductive age with PMDD were treated initially with YAZ or placebo for up to 3 cycles followed by a washout cycle and then crossed over to the alternate medication for 3 cycles.
Efficacy was assessed in both studies by the change from baseline during treatment using a scoring system based on the first 21 items of the Daily Record of Severity of Problems. Each of the 21 items was rated on a scale from 1 (not at all) to 6 (extreme); thus a maximum score of 126 was possible. In both trials, women who received YAZ had statistically significantly greater improvement in their Daily Record of Severity of Problems scores. In the primary study, the aver-age decrease (improvement) from baseline was 37.5 points in women taking YAZ, compared to 30.0 points in women taking placebo.
In two multicenter, double blind, randomized, placebo-controlled studies, 889 subjects, ages 14 to 45 years, with moderate acne received YAZ or placebo for six 28 day cycles. The primary efficacy endpoints were the percent change in inflammatory lesions, non-inflammatory lesions, total lesions, and the percentage of subjects with a "clear" or "almost clear" rating on the Investigator's Static Global Assessment (ISGA) scale on day 15 of cycle 6, as presented in Table III:

To achieve maximum contraceptive and PMDD effectiveness, YAZ (drospirenone and ethinyl estradiol) must be taken exactly as directed at intervals not exceeding 24 hours.
YAZ consists of 24 light pink active tablets of a monophasic combined hormonal preparation plus 4 inert white tablets. The dosage of YAZ is one light pink tablet daily for 24 consecutive days followed by 4 white inert tablets per menstrual cycle. A patient should begin to take YAZ either on the first day of her menstrual period (Day 1 Start) or on the first Sunday after the onset of her menstrual period (Sunday Start).
Day 1 Start. During the first cycle of YAZ use, the patient should be instructed to take one light pink YAZ daily, beginning on Day one (1) of her menstrual cycle. (The first day of menstruation is Day one.) She should take one light pink YAZ daily for 24 consecutive days, followed by one white inert tablet daily on menstrual cycle days 25 through 28. It is recommended that YAZ be taken at the same time each day, preferably after the evening meal or at bedtime. YAZ can be taken without regard to meals. If YAZ is first taken later than the first day of the menstrual cycle, YAZ should not be considered effective as a contraceptive until after the first 7 consecutive days of product administration. The possibility of ovulation and conception prior to initiation of medication should be considered.
Sunday Start. During the first cycle of YAZ use, the patient should be instructed to take one light pink YAZ daily, beginning on the first Sunday after the onset of her menstrual period. She should take one light pink YAZ daily for 24 consecutive days, followed by one white inert tablet daily on menstrual cycle days 25 through 28. It is recommended that YAZ be taken at the same time each day, preferably after the evening meal or at bedtime. YAZ can be taken without regard to meals. YAZ should not be considered effective as a contraceptive until after the first 7 consecutive days of product administration. The possibility of ovulation and conception prior to initiation of medication should be considered.
The patient should begin her next and all subsequent 28-day regimens of YAZ on the same day of the week that she began her first regimen, following the same schedule. She should begin taking her light pink tablets on the next day after ingestion of the last white tablet, regardless of whether or not a menstrual period has occurred or is still in progress. Anytime a subsequent cycle of YAZ is started later than the day following administration of the last white tablet, the patient should use another method of contraception until she has taken a light pink YAZ daily for seven consecutive days.
When switching from another oral contraceptive, YAZ should be started on the same day that a new pack of the previous oral contraceptive would have been started.
Withdrawal bleeding usually occurs within 3 days following the last light pink tablet. If spotting or breakthrough bleeding occurs while taking YAZ, the patient should be instructed to continue taking her YAZ as instructed and by the regimen described above. She should be instructed that this type of bleeding is usually transient and without significance; however, if the bleeding is persistent or pro-longed, the patient should be advised to consult her physician.
Although the occurrence of pregnancy is low if YAZ is taken according to directions, if withdrawal bleeding does not occur, the possibility of pregnancy must be considered. If the patient has not adhered to the prescribed dosing schedule (missed one or more active tablets or started taking them on a day later than she should have), the possibility of pregnancy should be considered at the time of the first missed period and appropriate diagnostic measures taken. If the patient has adhered to the pre-scribed regimen and misses two consecutive periods, pregnancy should be ruled out. Hormonal contraceptives should be discontinued if pregnancy is confirmed.
The risk of pregnancy increases with each active light pink tablet missed. For additional patient instructions regarding missed pills, see the "WHAT TO DO IF YOU MISS PILLS" section in the DETAILED PATIENT LABELING which follows. If breakthrough bleeding occurs following missed tablets, it will usually be transient and of no consequence. If the patient misses one or more white tablets, she should still be protected against pregnancy provided she begins taking light pink tablets again on the proper day.
In the nonlactating mother, YAZ may be initiated 4-6 weeks postpartum, for contraception. When the tablets are administered in the postpartum period, the increased risk of thromboembolic disease associated with the postpartum period must be considered. (See CONTRAINDICATIONS, WARNINGS, and PRECAUTIONS concerning thromboembolic disease.)
The timing and initiation of dosing with YAZ in women with acne should follow the guideline for use of YAZ as an oral contraceptive. The 28-day dosage regimen for YAZ for treating facial acne consists of one active tablet daily for 24 consecutive days followed by one inert tablet daily for 4 days. After 28 tablets are taken, a new course is started the next day.
YAZ (drospirenone and ethinyl estradiol) Tablets are available in packages of 3 BLISTER packs (NDC 50419-405-03). Each pack contains 24 active light pink round, unscored, film-coated tablets debossed with a "DS" in a regular hexagon on one side, each containing 3 mg drospirenone and 0.02 mg ethinyl estradiol, and 4 inert white round, unscored, film-coated tablets debossed with a "DP" in a regular hexagon on one side.
Store at 25° C (77° F); excursions permitted to 15-30° C (59-86° F) [See USP Controlled Room Temperature].

An increased risk of the following serious adverse reactions has been associated with the use of oral contraceptives (see WARNINGS).
There is evidence of an association between the following conditions and the use of oral contraceptives:
The following adverse reactions have been reported in patients receiving oral contraceptives and are believed to be drug-related:
The following adverse reactions have been reported in users of oral contraceptives and a causal association has been neither confirmed nor refuted:
The most frequent (> 1%) treatment-emergent adverse events, listed in descending order, reported with the use of YAZ in the contraception clinical trials, which may or not be drug related, included: upper respiratory infection, headache, breast pain, vaginal moniliasis, leukorrhea, diarrhea, nausea, vomiting, vaginitis, abdominal pain, flu syndrome, dysmenorrhea, moniliasis, allergic reaction, urinary tract infection, accidental injury, cystitis, tooth disorder, sore throat, infection, fever, surgery, sinusitis, back pain, emotional liability, migraine, suspicious Papanicolaou smear, dyspepsia, rhinitis, acne, gastroenteritis, bronchitis, pharyngitis, skin disorder, inter-menstrual bleeding, decreased libido, weight gain, pain, depression, increased cough, dizziness, menstrual disorder, pain in extremity, pelvic pain, and asthenia.
The most frequent (> 1%) treatment-emergent adverse events, listed in descending order, reported with the use of YAZ in the PMDD clinical trials, which may or not be drug related, included: intermenstrual bleeding, headache, nausea, breast pain, upper respiratory infection, asthenia, abdominal pain, decreased libido, emotional lability, suspicious Papanicolaou smear, nervousness, menorrhagia, pain in extremity, depression, menstrual disorder, migraine, sinusitis, weight gain, vaginal moniliasis, vaginitis, hyperlipidemia, back pain, diarrhea, increased appetite, enlarged abdomen, accidental injury, acne, dysmenorrhea, and urinary tract infection.
The most frequent (> 1%) treatment-emergent adverse events, listed in descending order, reported with the use of YAZ in the acne clinical trials, which may or not be drug related, included: upper respiratory infection, metrorrhagia, headache, suspicious Papanicolaou smear, nausea, sinusitis, vaginal moniliasis, flu syndrome, menorrhagia, depression, emotional lability, abdominal pain, gastroenteritis, urinary tract infection, tooth disorder, infection, vomiting, pharyngitis, breast pain, dysmenorrhea, menstrual disorder, accidental injury, asthenia, sore throat, weight gain, arthralgia, bronchitis, rhinitis, amenorrhea, and urine abnormality.
Effects of Other Drugs on Combined Hormonal Contraceptives Rifampin: Metabolism of ethinyl estradiol and some progestins (e.g., norethindrone) is increased by rifampin. A reduction in contraceptive effectiveness and an increase in menstrual irregularities have been associated with concomitant use of rifampin.
Minocycline: Minocycline-related changes in estradiol, progesterone, FSH and LH plasma levels, breakthrough bleeding, or contraceptive failure cannot be ruled out. Anticonvulsants: Anticonvulsants such as phenobarbital, phenytoin, and carbamazepine have been shown to increase the metabolism of ethinyl estradiol and/or some progestins, which could result in a reduction of contraceptive effectiveness. Antibiotics: Pregnancy while taking combined hormonal contraceptives has been reported when the combined hormonal contraceptives were administered with antimicrobials such as ampicillin, tetracycline, and griseofulvin. However, clinical pharmacokinetic studies have not demonstrated any consistent effects of antibiotics (other than rifampin-see above) on plasma concentrations of synthetic steroids. See also separate discussion on minocycline (above).
Atorvastatin: Coadministration of atorvastatin and an oral contraceptive increased AUC values for norethindrone and ethinyl estradiol by approximately 30% and 20%, respectively. St. John's Wort: Herbal products containing St. John's Wort (hypericum perforatum) may induce hepatic enzymes (cytochrome P450) and p-glycoprotein transporter and may reduce the effectiveness of oral contraceptives and emergency contraceptive pills. This may also result in breakthrough bleeding. Other: Ascorbic acid and acetaminophen may increase plasma concentrations of some synthetic estrogens, possibly by inhibition of conjugation.
Metabolism of DRSP and potential effects of DRSP on hepatic cytochrome P450 (CYP) enzymes have been investigated in in vitro and in vivo studies (see Metabolism). In in vitro studies DRSP did not affect turnover of model substrates of CYP1A2 and CYP2D6, but had an inhibitory influence on the turnover of model substrates of CYP1A1, CYP2C9, CYP2C19 and CYP3A4 with CYP2C19 being the most sensitive enzyme. The potential effect of DRSP on CYP2C19 activity was investigated in a clinical pharmacokinetic study using omeprazole as a marker substrate. In the study with 24 postmenopausal women [including 12 women with homozygous (wild type) CYP2C19 genotype and 12 women with heterozygous CYP2C19 genotype] the daily oral administration of 3 mg DRSP for 14 days did not affect the oral clearance of omeprazole (40 mg, single oral dose) and the CYP2C19 product 5-hydroxy omeprazole. Furthermore, no significant effect of DRSP on the systemic clearance of the CYP3A4 product omeprazole sulfone was found. These results demonstrate that DRSP did not inhibit CYP2C19 and CYP3A4 in vivo.
Two additional clinical drug-drug interaction studies using simvastatin and midazolam as marker substrates for CYP3A4 were each performed in 24 healthy postmenopausal women. The results of these studies demonstrated that pharmacokinetics of the CYP3A4 substrates were not influenced by steady state DRSP concentrations achieved after administration of 3 mg DRSP/day.
There is a potential for an increase in serum potassium in women taking YAZ with other drugs (see BOLDED WARNING). Of note, occasional or chronic use of NSAID medication was not restricted in any of the clinical trials with YAZ.
A drug-drug interaction study of DRSP 3 mg/estradiol (E2) 1 mg versus placebo was performed in 24 mildly hypertensive post-menopausal women taking enalapril maleate 10 mg twice daily. Potassium levels were obtained every other day for a total of 2 weeks in all subjects. Mean serum potassium levels in the DRSP/E2 treatment group relative to baseline were 0.22 mEq/L higher than those in the placebo group. Serum potassium concentrations also were measured at multiple timepoints over 24 hours at baseline and on Day 14. On Day 14, the ratios for serum potassium Cmax and AUC in the DRSP/E2 group to those in the placebo group were 0.955 (90% CI: 0.914, 0.999) and 1.01 (90% CI: 0.944, 1.08), respectively. No patient in either treatment group developed hyperkalemia (serum potassium concentrations >5.5 mEq/L).
Combined oral contraceptives containing ethinyl estradiol may inhibit the metabolism of other compounds. Increased plasma concentrations of cyclosporine, prednisolone, and theophylline have been reported with concomitant administration of oral contraceptives. In addition, oral contraceptives may induce the conjugation of other compounds. Decreased plasma concentrations of acetaminophen and increased clearance on temazepam, salicylic acid, morphine, and clofibric acid have been noted when these drugs were administered with oral contraceptives.
Certain endocrine- and liver-function tests and blood components may be affected by oral contraceptives:
a. Increased prothrombin and factors VII, VIII, IX and X; decreased antithrombin 3; increased norepinephrine-induced platelet aggregability.
b. Increased thyroid-binding globulin (TBG) leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 by column or by radioimmunoassay. Free T3 resin uptake is decreased, reflecting the elevated TBG, free T4 concentration is unaltered.
c. Other binding proteins may be elevated in serum.
d. Sex-hormone-binding globulins are increased and result in elevated levels of total circulating sex steroids and corticoids; how-ever, free or biologically active levels remain unchanged.
e. Triglycerides may be increased.
f.Glucose tolerance may be decreased.
g. Serum folate levels may be depressed by oral contraceptive therapy. This may be of clinical significance if a woman becomes pregnant shortly after discontinuing oral contraceptives.

Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.
YAZ contains 3 mg of the progestin drospirenone that has antimineralocorticoid activity, including the potential for hyperkalemia in high-risk patients, comparable to a 25 mg dose of spironolactone. YAZ should not be used in patients with conditions that predispose to hyperkalemia (i.e. renal insufficiency, hepatic dysfunction and adrenal insufficiency). Women receiving daily, long-term treatment for chronic conditions or diseases with medications that may increase serum potassium should have their serum potassium level checked during the first treatment cycle. Medications that may increase serum potassium include ACE inhibitors, angiotensin - II receptor antagonists, potassium-sparing diuretics, potassium supplementation, heparin, aldosterone antagonists, and NSAIDS.
The use of oral contraceptives is associated with increased risks of several serious conditions including venous and arterial thrombotic and thromboembolic events (such as myocardial infarction, thromboembolism, stroke), hepatic neoplasia, gallbladder disease, and hypertension. The risk of serious morbidity or mortality is very small in healthy women without underlying risk factors. The risk of morbidity and mortality increases significantly in the presence of other underlying risk factors such as hypertension, hyperlipidemias, obesity and diabetes.
Practitioners prescribing oral contraceptives should be familiar with the following information relating to these risks. The information contained in this package insert is based principally on studies carried out in patients who used oral contraceptives with higher formulations of estrogens and progestogens than those in common use today. The effect of long-term use of the oral contraceptives with lower formulations of both estrogens and progestogens remains to be determined.
Throughout this labeling, epidemiologic studies reported are of two types: retrospective or case control studies and prospective or cohort studies. Case control studies provide a measure of the relative risk of a disease, namely, a ratio of the incidence of a disease among oral contraceptive users to that among nonusers. The relative risk does not provide information on the actual clinical occurrence of a disease. Cohort studies provide a measure of attributable risk, which is the difference in the incidence of disease between oral contraceptive users and nonusers. The attributable risk does provide information about the actual occurrence of a disease in the population. For further information, the reader is referred to a text on epidemiologic methods.
An increased risk of myocardial infarction has been attributed to oral contraceptive use. This risk is primarily in smokers or women with other underlying risk factors for coronary-artery disease such as hypertension, hypercholesterolemia, morbid obesity, and diabetes. The relative risk of heart attack for current oral contraceptive users has been estimated to be two to six. The risk is very low under the age of 30.
Smoking in combination with oral contraceptive use has been shown to contribute substantially to the incidence of myocardial infarctions in women in their mid-thirties or older with smoking accounting for the majority of excess cases. Mortality rates associated with circulatory disease have been shown to increase substantially in smokers over the age of 35 and nonsmokers over the age of 40 (Table IV) among women who use oral contraceptives.

Oral contraceptives may compound the effects of well-known risk factors, such as hypertension, diabetes, hyperlipidemias, age and obesity. In particular, some progestogens are known to decrease HDL cholesterol and cause glucose intolerance, while estrogens may create a state of hyperinsulinism. Oral contraceptives have been shown to increase blood pressure among users (see section 9 in WARNINGS). Similar effects on risk factors have been associated with an increased risk of heart disease. Oral contraceptives must be used with caution in women with cardiovascular disease risk factors.
An increased risk of thromboembolic and thrombotic disease associated with the use of oral contraceptives is well established. Case control studies have found the relative risk of users compared to nonusers to be 3 for the first episode of superficial venous thrombosis, 4 to 11 for deep vein thrombosis or pulmonary embolism, and 1.5 to 6 for women with predisposing conditions for venous thromboembolic disease. Cohort studies have shown the relative risk to be somewhat lower, about 3 for new cases and about 4.5 for new cases requiring hospitalization. The risk of thromboembolic disease due to oral contraceptives is not related to length of use and disappears after pill use is stopped.
A two- to four-fold increase in the relative risk of post-operative thromboembolic complications has been reported with the use of oral contraceptives. The relative risk of venous thrombosis in women who have predisposing conditions is twice that of women without such medical conditions. If feasible, oral contraceptives should be discontinued from at least four weeks prior to and for two weeks after elective surgery of a type associated with an increase in risk of thromboembolism and during and following prolonged immobilization. Since the immediate postpartum period is also associated with an increased risk of thromboembolism, combined oral contraceptives should be started no earlier than four to six weeks after delivery and at that time only in women who elect not to breast feed.
Oral contraceptives have been shown to increase both the relative and attributable risks of cerebrovascular events (thrombotic and hemorrhagic strokes), although, in general, the risk is greatest among older (>35 years), hypertensive women who also smoke. Hypertension was found to be a risk factor, for both users and nonusers, for both types of strokes, while smoking interacted to increase the risk for hemorrhagic strokes.
In a large study, the relative risk of thrombotic strokes has been shown to range from 3 for normotensive users to 14 for users with severe hypertension. The relative risk of hemorrhagic stroke is reported to be 1.2 for nonsmokers who used oral contraceptives, 2.6 for smokers who did not use oral contraceptives, 7.6 for smokers who used oral contraceptives, 1.8 for normotensive users and 25.7 for users with severe hypertension. The attributable risk is also greater in older women. Oral contraceptives also increase the risk for stroke in women with other underlying risk factors such as certain inherited or acquired thrombophilias, hyperlipidemias, and obesity. Women with migraine (particularly migraine with aura) who take combination oral contraceptives may be at an increased risk of stroke.
A positive association has been observed between the amount of estrogen and progestogen in oral contraceptives and the risk of vascular disease. A decline in serum high-density lipoproteins (HDL) has been reported with many progestational agents. A decline in serum high-density lipoproteins has been associated with an increased incidence of ischemic heart disease. Because estrogens increase HDL cholesterol, the net effect of an oral contraceptive depends on a balance achieved between doses of estrogen and progestogen and the nature and absolute amount of progestogen used in the contraceptive. The amount of both hormones should be considered in the choice of an oral contraceptive.
Minimizing exposure to estrogen and progestogen is in keeping with good principles of therapeutics. For any particular estrogen/progestogen combination, the dosage regimen prescribed should be one which contains the least amount of estrogen and progestogen that is compatible with a low failure rate and the needs of the individual patient. New acceptors of oral contraceptive agents should be started on preparations containing the lowest estrogen content that is judged appropriate for the individual patient.
There are two studies which have shown persistence of risk of vascular disease for ever-users of oral contraceptives. In a study in the United States, the risk of developing myocardial infarction after discontinuing oral contraceptives persists for at least 9 years for women aged 40 to 49 years who had used oral contraceptives for five or more years, but this increased risk was not demonstrated in other age groups. In another study in Great Britain, the risk of developing cerebrovascular disease persisted for at least 6 years after discontinuation of oral contraceptives, although excess risk was very small. However, both studies were performed with oral contraceptive formulations containing 50 micrograms or higher of estrogens.
One study gathered data from a variety of sources which have estimated the mortality rate associated with different methods of contraception at different ages (Table V). These estimates include the combined risk of death associated with contraceptive methods plus the risk attributable to pregnancy in the event of method failure. Each method of contraception has its specific benefits and risks. The study concluded that with the exception of oral contraceptive users 35 and older who smoke and 40 and older who do not smoke, mortality associated with all methods of birth control is below that associated with childbirth.
The observation of a possible increase in risk of mortality with age for oral contraceptive users is based on data gathered in the 1970's- but not reported until 1983. However, current clinical practice involves the use of lower estrogen dose formulations combined with careful restriction of oral contraceptive use to women who do not have the various risk factors listed in this labeling.
Because of these changes in practice and, also, because of some limited new data which suggest that the risk of cardiovascular is-ease with the use of oral contraceptives may now be less than previously observed, the Fertility and Maternal Health Drugs Advisory Committee was asked to review the topic in 1989. The Committee concluded that although cardiovascular disease risks may be increased with oral contraceptive use after age 40 in healthy non-smoking women (even with the newer low-dose formulations), there are greater potential health risks associated with pregnancy in older women and with the alternative surgical and medical procedures which may be necessary if such women do not have access to effective and acceptable means of contraception.
Therefore, the Committee recommended that the benefits of oral contraceptive use by healthy nonsmoking women over 40 may out-weigh the possible risks. Of course, women of all ages who take oral contraceptives, should take the lowest possible dose formulation that is effective.

Numerous epidemiological studies have been performed on the incidence of breast, endometrial, ovarian and cervical cancer in women using oral contraceptives.
Although the risk of having breast cancer diagnosed may be slightly increased among current and recent users of combined oral contraceptives (RR=1.24), this excess risk decreases over time after combination oral contraceptive discontinuation and by 10 years after cessation the increased risk disappears. The risk does not increase with duration of use and no consistent relationships have been found with dose or type of steroid. The patterns of risk are also similar regardless of a woman's reproductive history or her family breast cancer history. The subgroup for whom risk has been found to be significantly elevated is women who first used oral contraceptives before age 20, but because breast cancer is so rare at these young ages, the number of cases attributable to this early oral contraceptive use is extremely small.
Breast cancers diagnosed in current or previous OC users tend to be less clinically advanced than in never users.
Women who currently have or have had breast cancer should not use oral contraceptives because breast cancer is a hormonally-sensitive tumor.
Some studies suggest that oral contraceptive use has been associated with an increase in the risk of cervical intraepithelial neoplasia in some populations of women. However, there continues to be controversy about the extent to which such findings may be due to differences in sexual behavior and other factors. In spite of many studies of the relationship between oral contraceptive use and breast and cervical cancers, a cause-and-effect relationship has not been established.
Benign hepatic adenomas are associated with oral contraceptive use, although the incidence of benign tumors is rare in the United States. Indirect calculations have estimated the attributable risk to be in the range of 3.3 cases/100,000 for users, a risk that increases after four or more years of use. Rupture of rare, benign, hepatic adenomas may cause death through intra-abdominal hemorrhage.
Studies from Britain have shown an increased risk of developing hepatocellular carcinoma in long-term (>8 years) oral contraceptive users. However, these cancers are extremely rare in the U.S. and the attributable risk (the excess incidence) of liver cancers in oral contraceptive users approaches less than one per million users.
There have been clinical case reports of retinal thrombosis associated with the use of oral contraceptives, which may lead to partial or complete loss of vision. Oral contraceptives should be discontinued if there is unexplained partial or complete loss of vision; onset of proptosis or diplopia; papilledema; or retinal vascular lesions. Appropriate diagnostic and therapeutic measures should be undertaken immediately.
Extensive epidemiological studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy. Studies also do not suggest a teratogenic effect, particularly in so far as cardiac anomalies and limb-reduction defects are concerned, when taken inadvertently during early pregnancy.
The administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy. Oral contraceptives should not be used during pregnancy to treat threatened or habitual abortion. (see CONTRAINDICATIONS)
It is recommended that for any patient who has missed two consecutive periods, pregnancy should be ruled out. If the patient has not adhered to the prescribed dosing schedule, the possibility of pregnancy should be considered at the time of the first missed period. Oral contraceptive use should be discontinued if pregnancy is confirmed.
Earlier studies have reported an increased lifetime relative risk of gallbladder surgery in users of oral contraceptives and estrogens. More recent studies, however, have shown that the relative risk of developing gallbladder disease among oral contraceptive users may be minimal. The recent findings of minimal risk may be related to the use of oral contraceptive formulations containing lower hormonal doses of estrogens and progestogens.
Oral contraceptives have been shown to cause glucose intolerance in a significant percentage of users. Oral contraceptives containing greater than 75 micrograms of estrogens cause hyperinsulinism, while lower doses of estrogen cause less glucose intolerance. Progestogens increase insulin secretion and create insulin resistance, this effect varying with different progestational agents. However, in the non diabetic woman, oral contraceptives appear to have no effect on fasting blood glucose. Because of these demonstrated effects, prediabetic and diabetic women should be carefully observed while taking oral contraceptives.
A small proportion of women will have persistent hypertriglyceridemia while on the pill. As discussed earlier (see WARNINGS 1a. and 1d.), changes in serum triglycerides and lipoprotein levels have been reported in oral contraceptive users.
Women with severe hypertension should not be started on hormonal contraceptives (see CONTRAINDICATIONS).
An increase in blood pressure has been reported in women taking oral contraceptives and this increase is more likely in older oral contraceptive users and with continued use. Data from the Royal College of General Practitioners and subsequent randomized trials have shown that the incidence of hypertension increases with increasing concentrations of progestogens.
Women with a history of hypertension or hypertension-related diseases, or renal disease should be encouraged to use another method of contraception. If women with hypertension elect to use oral contraceptives, they should be monitored closely, and if significant elevation of blood pressure occurs, oral contraceptives should be discontinued. For most women, elevated blood pressure will return to normal after stopping oral contraceptives and there is no difference in the occurrence of hypertension among ever- and never-users.
The onset or exacerbation of migraine or development of headache with a new pattern which is recurrent, persistent or severe requires discontinuation of oral contraceptives and evaluation of the cause.
Breakthrough bleeding and spotting are sometimes encountered in patients on oral contraceptives, especially during the first three months of use. Nonhormonal causes should be considered and adequate diagnostic measures taken to rule out malignancy or pregnancy in the event of breakthrough bleeding, as in the case of any abnormal vaginal bleeding. If pathology has been excluded, time or a change to another formulation may solve the problem. In the event of amenorrhea, pregnancy should be ruled out.
Some women may encounter post-pill amenorrhea or oligomenorrhea, especially when such a condition was pre-existent.
Patients should be counseled that this product does not protect against HIV infection (AIDS) and other sexually transmitted diseases.
A periodic personal and family medical history and complete physical examination are appropriate for all women, including women using oral contraceptives. The physical examination, how-ever, may be deferred until after initiation of oral contraceptives if requested by the woman and judged appropriate by the clinician. The physical examination should include special reference to blood pressure, breasts, abdomen and pelvic organs, including cervical cytology and relevant laboratory tests. In case of undiagnosed, persistent or recurrent abnormal vaginal bleeding, appropriate measures should be conducted to rule out malignancy. Women with a strong family history of breast cancer or who have breast nodules should be monitored with particular care.
Women who are being treated for hyperlipidemias should be followed closely if they elect to use oral contraceptives. Some progestogens may elevate LDL levels and may render the control of hyperlipidemias more difficult. (See WARNINGS 1.d.) In patients with familial defects of lipoprotein metabolism receiving estrogen-containing preparations, there have been case reports of significant elevations of plasma triglycerides leading to pancreatitis.
If jaundice develops in any woman receiving oral contraceptives, the medication should be discontinued. Steroid hormones may be poorly metabolized in patients with impaired liver function.
Oral contraceptives may cause some degree of fluid retention. They should be prescribed with caution, and only with careful monitoring, in patients with conditions which might be aggravated by fluid retention.
Women with a history of depression should be carefully observed and the drug discontinued if depression recurs to a serious degree. Patients becoming significantly depressed while taking oral contraceptives should stop the medication and use an alternate method of contraception in an attempt to determine whether the symptom is drug related.
Contact-lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist.
In a 24 month oral carcinogenicity study in mice dosed with 10 mg/kg/day drospirenone alone or 1 + 0.01, 3 + 0.03 and 10 + 0.1 mg/kg/day of drospirenone and ethinyl estradiol, 0.1 to 2 times the exposure (AUC of drospirenone) of women taking a contraceptive dose, there was an increase in carcinomas of the harderian gland in the group that received the high dose of drospirenone alone. In a similar study in rats given 10 mg/kg/day drospirenone alone or 0.3 + 0.003, 3 + 0.03 and 10 + 0.1 mg/kg/day drospirenone and ethinyl estradiol, 0.8 to 10 times the exposure of women taking a contraceptive dose, there was an increased incidence of benign and total (benign and malignant) adrenal gland pheochromocytomas in the group receiving the high dose of drospirenone. Drospirenone was not mutagenic in a number of in vitro (Ames, Chinese Hamster Lung gene mutation and chromosomal damage in human lymphocytes) and in vivo (mouse micronucleus) genotoxicity tests. Drospirenone increased unscheduled DNA synthesis in rat hepatocytes and formed adducts with rodent liver DNA but not with human liver DNA. (See WARNINGS.)
Pregnancy category X. (See CONTRAINDICATIONS and WARNINGS) Estrogens and progestins should not be used during pregnancy. Fourteen pregnancies that occurred during exposure with 3 mg DRSP/0.03 mg EE tablets in utero (none with more than a single cycle of exposure) have been identified. One infant was born with esophageal atresia. A causal association with the 3 mg DRSP/0.03 mg EE tablet is unknown.
Twelve pregnancies that occurred with YAZ exposure in utero (none with more than a single cycle of exposure) have been identified. There were no known cases of congenital anomalies. A teratology study in pregnant rats given drospirenone orally at doses of 5, 15 and 45 mg/kg/day, 6 to 50 times the human exposure based on AUC of drospirenone, resulted in an increased number of fetuses with delayed ossification of bones of the feet in the two higher doses. A similar study in rabbits dosed orally with 1, 30 and 100 mg/kg/day drospirenone, 2 to 27 times the human exposure, resulted in an increase in fetal loss and retardation of fetal development (delayed ossification of small bones, multiple fusions of ribs) at the high dose only. When drospirenone was administered with ethinyl estradiol (100:1) during late pregnancy (the period of genital development) at doses of 5, 15 and 45 mg/kg, there was a dose dependent increase in feminization of male rat fetuses. In a study in 36 cynomolgous monkeys, no teratogenic or feminization effects were observed with orally administered drospirenone and ethinyl estradiol (100:1) at doses up to 10 mg/kg/day drospirenone, 30 times the human exposure.
Small amounts of oral contraceptive steroids have been identified in the milk of nursing mothers, and a few adverse effects on the child have been reported, including jaundice and breast enlargement. In addition, oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. If possible, the nursing mother should be advised not to use oral contraceptives but to use other forms of contraception until she has completely weaned her child.
After oral administration of 3 mg DRSP/0.03 mg EE tablets about 0.02% of the drospirenone dose was excreted into the breast milk of postpartum women within 24 hours. This results in a maximal daily dose of about 3 mcg drospirenone in an infant.
Safety and efficacy of YAZ has been established in women of reproductive age. Safety and efficacy are expected to be the same for postpubertal adolescents under the age of 16 and for users 16 years and older. Use of this product before menarche is not indicated.

Serious ill effects have not been reported following acute ingestion of large doses of other oral contraceptives by young children. Overdosage may cause nausea, and withdrawal bleeding may occur in females. Drospirenone, however, is a spironolactone analogue which has antimineralocorticoid properties. Serum concentration of potassium and sodium, and evidence of metabolic acidosis, should be monitored in cases of overdose.
The following non-contraceptive health benefits related to the use of oral contraceptives are supported by epidemiological studies which largely utilized oral contraceptive formulations containing doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg mestranol.
Effects on menses:
YAZ should not be used in women who have the following:
Last updated on RxList: 4/20/2007
Combination oral contraceptives (COCs) act by suppression of gonadotropins. Although the primary mechanism of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increases the difficulty of sperm entry into the uterus) and the endometrium (which reduces the likelihood of implantation).
Drospirenone is a spironolactone analogue with antimineralocorticoid activity. Preclinical studies in animals and in vitro have shown that drospirenone has no androgenic, estrogenic, glucocorticoid, or antiglucocorticoid activity. Preclinical studies in animals have also shown that drospirenone has antiandrogenic activity.
Acne vulgaris is a skin condition with a multifactorial etiology including androgen stimulation of sebum production. While the combination of ethinyl estradiol and drospirenone increases sex hormone binding globulin (SHBG) and decreases free testosterone, the relationship between these changes and a decrease in the severity of facial acne in otherwise healthy women with this skin condition has not been established. The impact of the antiandrogenic activity of drospirenone on acne is not known.
The absolute bioavailability of drospirenone (DRSP) from a single entity tablet is about 76%. The absolute bioavailability of ethinyl estradiol (EE) is approximately 40% as a result of presystemic conjugation and first-pass metabolism. The absolute bioavailability of YAZ, which is a combination tablet of drospirenone and ethinyl estradiol stabilized by betadex as a clathrate (molecular inclusion complex), has not been evaluated. The bioavailability of EE is similar when dosed via a betadex clathrate formulation compared to when it is dosed as a free steroid. Serum concentrations of DRSP and EE reached peak levels within 1-2 hours after administration of YAZ.
The pharmacokinetics of DRSP are dose proportional following single doses ranging from 1-10 mg. Following daily dosing of YAZ, steady state DRSP concentrations were observed after 8 days. There was about 2 to 3 fold accumulation in serum Cmax and AUC (0-24h) values of DRSP following multiple dose administration of YAZ (see Table I).
For EE, steady-state conditions are reported during the second half of a treatment cycle. Following daily administration of YAZ serum Cmax and AUC (0-24h) values of EE accumulate by a factor of about 1.5 to 2 (see Table I).

The rate of absorption of DRSP and EE following single administration of a formulation similar to YAZ was slower under fed (high fat meal) conditions with the serum Cmax being reduced about 40% for both components. The extent of absorption of DRSP, however, remained unchanged. In contrast, the extent of absorption of EE was reduced by about 20% under fed conditions.
DRSP and EE serum levels decline in two phases. The apparent volume of distribution of DRSP is approximately 4 L/kg and that of EE is reported to be approximately 4 - 5 L/kg. DRSP does not bind to sex hormone binding globulin (SHBG) or corticosteroid binding globulin (CBG) but binds about 97% to other serum proteins. Multiple dosing over 3 cycles resulted in no change in the free fraction (as measured at trough levels). EE is reported to be highly but non-specifically bound to serum albumin (approximately 98.5 %) and induces an increase in the serum concentrations of both SHBG and CBG. EE induced effects on SHBG and CBG were not affected by variation of the DRSP dosage in the range of 2 to 3 mg.
The two main metabolites of DRSP found in human plasma were identified to be the acid form of DRSP generated by opening of the lactone ring and the 4,5-dihydrodrospirenone-3-sulfate. These metabolites were shown not to be pharmacologically active. In in vitro studies with human liver microsomes, DRSP was metabolized only to a minor extent mainly by Cytochrome P450 3A4 (CYP3A4).
EE has been reported to be subject to presystemic conjugation in both small bowel mucosa and the liver. Metabolism occurs primarily by aromatic hydroxylation but a wide variety of hydroxylated and methylated metabolites are formed. These are present as free metabolites and as conjugates with glucuronide and sulfate. CYP3A4 in the liver is responsible for the 2-hydroxylation which is the major oxidative reaction. The 2-hydroxy metabolite is further transformed by methylation and glucuronidation prior to urinary and fecal excretion.
DRSP serum levels are characterized by a terminal disposition phase half-life of approximately 30 hours after both single and multiple dose regimens. Excretion of DRSP was nearly complete after ten days and amounts excreted were slightly higher in feces compared to urine. DRSP was extensively metabolized and only trace amounts of unchanged DRSP were excreted in urine and feces. At least 20 different metabolites were observed in urine and feces. About 38-47% of the metabolites in urine were glucuronide and sulfate conjugates. In feces, about 17-20% of the metabolites were excreted as glucuronides and sulfates.
For EE the terminal disposition phase half-life has been reported to be approximately 24 hours. EE is not excreted unchanged. EE is excreted in the urine and feces as glucuronide and sulfate conjugates and undergoes enterohepatic circulation.
No clinically significant difference was observed between the pharmacokinetics of DRSP or EE in Japanese versus Caucasian women (age 20-35) when YAZ was administered daily for 21 days.
Other ethnic groups have not been studied.
YAZ is contraindicated in patients with hepatic dysfunction (see CONTRAINDICATIONS and BOLDED WARNING). The mean expo-sure to DRSP in women with moderate liver impairment is approximately three times higher than the exposure in women with normal liver function. YAZ has not been studied in women with severe hepatic impairment.
YAZ is contraindicated in patients with renal insufficiency (see CONTRAINDICATIONS and BOLDED WARNING).
The effect of renal insufficiency on the pharmacokinetics of DRSP (3 mg daily for 14 days) and the effect of DRSP on serum potassium levels were investigated in female subjects (n = 28, age 30 - 65) with normal renal function and mild and moderate renal impairment. All subjects were on a low potassium diet. During the study 7 subjects continued the use of potassium sparing drugs for the treatment of the underlying illness. On the 14th day (steady-state) of DRSP treatment, serum DRSP levels in the group with mild renal impairment (creatinine clearance CLcr, 50-80 mL/min) were comparable to those in the group with normal renal function (CLcr, >80 mL/min). The serum DRSP levels were on average 37 % higher in the group with moderate renal impairment (CLcr, 30 - 50 mL/min) compared to those in the group with normal renal function. DRSP treatment was well tolerated by all groups. DRSP treatment did not show any clinically significant effect on serum potassium concentration. Although hyperkalemia was not observed in the study, in five of the seven subjects who continued use of potassium sparing drugs during the study, mean serum potassium levels increased by up to 0.33 mEq/L. Therefore, potential exists for hyperkalemia to occur in subjects with renal impairment whose serum potassium is in the upper reference range, and who are concomitantly using potassium sparing drugs.

BRIEF SUMMARY PATIENT PACKAGE INSERT
YAZ
(drospirenone and ethinyl estradiol) Tablets
containing the following:
24 light pink - "active" tablets
4 white - "inert" tablets
This product (like all oral contraceptives) is intended to pre-vent pregnancy. It does not protect against HIV infection (AIDS) and other sexually transmitted diseases. YAZ is different from other birth control pills because it contains the progestin drospirenone. Drospirenone may increase potassium. Therefore, you should not take YAZ if you have kidney, liver or adrenal disease because this could cause serious heart and health problems. Other drugs may also increase potassium. If you are currently on daily, long-term treatment for a chronic condition with any of the medications below, you should consult your healthcare provider about whether YAZ is right for you, and during the first month that you take YAZ, you should have a blood test to check your potassium level.
YAZ is an oral contraceptive, also known as a "birth control pill" or "the Pill." Oral contraceptives are taken to prevent pregnancy, and, when taken correctly without missing any pills, have a failure rate of approximately 1% per year (1 pregnancy per 100 women per year of use). The typical failure rate in pill users is approximately 5% per year (5 pregnancies per 100 women per year of use) when women who miss pills are included. Forgetting to take pills considerably increases the chances of pregnancy.
YAZ may also be taken to treat premenstrual dysphoric disorder (PMDD) if you choose to use the Pill for birth control. Unless you have already decided to use the Pill for birth control, you should not start YAZ to treat your PMDD because there are other medical therapies for PMDD that do not have the same risks as the Pill. PMDD is a mood disorder related to the menstrual cycle. PMDD significantly interferes with work or school, or with usual social activities and relationships with others. Symptoms include markedly depressed mood, anxiety or tension, mood swings, and persistent anger or irritability. Other features include decreased interest in usual activities, difficulty concentrating, lack of energy, change in appetite or sleep, and feeling out of control. Physical symptoms associated with PMDD may include breast tenderness, headache, joint and muscle pain, bloating and weight gain. These symptoms occur regularly before menstruation starts and go away within a few days following the start of the period. Diagnosis of PMDD should be made by healthcare providers.
You should only use YAZ for treatment of PMDD if you:
YAZ has not been shown to be effective for the treatment of pre-menstrual syndrome (PMS), a less serious cluster of symptoms occurring before menstruation. If you or your healthcare provider believes you have PMS, you should only take YAZ if you want to prevent pregnancy; and not for the treatment of PMS.
YAZ may also be taken to treat moderate acne in women who are able to and wish to use the pill for birth control.
Any woman who needs contraception (birth control) and chooses to use an oral contraceptive should understand the benefits and risks of using the Pill. This leaflet will give you much of the information you will need to help you decide if you should use the Pill for contraception and will also help you determine if you are at risk of developing any of the serious side effects of the Pill. It will tell you how to use the Pill properly so that it will be as effective as possible. However, this leaflet is not a replacement for a careful discussion between you and your healthcare professional. You should discuss the information provided in this leaflet with him or her, both when you first start taking the Pill and during your revisits. You should also follow your healthcare professional's advice with regard to regular check-up while you are on the Pill.
For the majority of women, oral contraceptives can be taken safely. But there are some women who are at high risk of developing certain serious diseases that can be life-threatening or may cause temporary or permanent disability or death. The risks associated with taking oral contraceptives increase significantly if you:
You should not take the pill if you suspect you are pregnant or have unexplained vaginal bleeding.
Although cardiovascular disease risks may be increased with oral contraceptive use after age 40 in healthy, non-smoking women (even with the newer low-dose formulations), there are also greater potential health risks associated with pregnancy in older women.
Cigarette smoking increases the risk of serious adverse effects on the heart and blood vessels from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should not smoke.
Most side effects of the pill are not serious. The most common such effects are nausea, vomiting, bleeding between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses. These side effects, especially nausea and vomiting may subside within the first three months of use.
The serious side effects of the pill occur very infrequently, especially if you are in good health and are young. However, you should know that the following medical conditions have been associated with or made worse by the pill:
Some studies have found an increase in the incidence of cancer or precancerous lesions of the cervix in women who use the pill. However, this finding may be related to factors other than the use of the pill.
The symptoms associated with these serious side effects are discussed in the detailed leaflet given to you with your supply of pills. Notify your doctor or healthcare provider if you notice any unusual physical disturbances while taking the pill. In addition, drugs such as rifampin, as well as some anticonvulsants, some antibiotics and some herbal products such as St. John's Wort, may decrease oral contraceptive effectiveness. Taking the pill may provide some important non-contraceptive benefits. These include less painful menstruation, less menstrual blood loss and anemia, fewer pelvic infections, and fewer cancers of the ovary and the lining of the uterus.
Be sure to discuss any medical condition you may have with your healthcare provider. Your healthcare provider will take a medical and family history before prescribing oral contraceptives and will examine you. The physical examination may be delayed to another time if you request it and the healthcare provider believes that it is appropriate to postpone it. You should be reexamined at least once a year while taking oral contraceptives. The detailed patient information booklet gives you further information which you should read and discuss with your healthcare provider.
This product (like all oral contraceptives) is intended to prevent pregnancy.
Oral contraceptives do not protect against HIV infection (AIDS) and other sexually
transmitted diseases such as chlamydia, genital herpes,

If you or your healthcare provider believes you have PMS, you should only take YAZ if you want to prevent pregnancy; and not for the treatment of PMS.
YAZ may also be taken to treat moderate acne in women who are able to and wish to use the pill for birth control.
Any woman who needs contraception (birth control) and chooses to use an oral contraceptive should understand the benefits and risks of using the Pill. This leaflet will give you much of the information you will need to help you decide if you should use the Pill for contraception and will also help you determine if you are at risk of developing any of the serious side effects of the Pill. It will tell you how to use the Pill properly so that it will be as effective as possible. However, this leaflet is not a replacement for a careful discussion between you and your healthcare professional. You should discuss the information provided in this leaflet with him or her, both when you first start taking the Pill and during your revisits. You should also follow your healthcare professional's advice with regard to regular check-ups while you are on the Pill.
Oral contraceptives or "birth control pills" or "the Pill" are used to prevent pregnancy and are more effective than most other nonsurgical methods of birth control. When they are taken correctly, the chance of becoming pregnant is less than 1% (one pregnancy per 100 women per year of use) when used perfectly, without missing any pills. Typical failure rates, including women who don't always follow the instructions exactly, are about 5% per year. The chance of becoming pregnant increases with each missed pill during a menstrual cycle.
In comparison, typical failure rates for other nonsurgical methods of birth control during the first year of use are as follows:

| Emergency Contraceptive Pills: Treatment initiated
within 72 hours after unprotected intercourse reduces the risk of pregnancy
by at least 75%.9 Lactational Amenorrhea Method: LAM is highly effective, temporary method of contraception.10 Source: Trussell J, Contraceptive efficacy. In Hatcher RA, Trussell J, Stewart F, Cates W, Stewart GK, Kowal D, Guest F, Contraceptive Technology: Seventeenth Revised Edition. New York NY: Irvington Publishers, 1998. 1 Among typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. 2 Among couples who initiate use of a method (not necessarily for the first time) and who use it perfectly (both consistently and correctly). The percentage who experience an accidental pregnancy during the first year if they do not stop use for any reason. 3 Among couples attempting to avoid pregnancy, the percentage who continue to use a method for one year. 4 The percents becoming pregnant in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% become pregnant within one year. This estimate was lowered slightly (to 85%) to represent the percentage who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether. 5 Foams, creams, gels vaginal suppositories, and vaginal film. 6 Cervical mucus (ovulation) method supplemented by calendar in the pre-ovulatory and basal body temperature in the post-ovulatory phases. 7 With spermicidal cream or jelly. 8 Without spermicides. 9 The treatment schedule is one dose within 72 hours after unprotected intercourse, and a second dose 12 hours after the first dose. The Food and Drug Administration has declared the following brands of oral contraceptives to be safe and effective for emergency contraception: Ovral (1 dose is 2 white pills), Alesse (1 dose is 5 pink pills), Nordette or Levlen (1 dose is 2 light-orange pills), Lo/Ovral (1 dose is 4 white pills), Triphasil or Tri-Levlen (1 dose is 4 yellow pills). 10 However, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency or duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches six months of age. |

YAZ may also be taken to treat moderate acne if all of the following are true:
WHO SHOULD NOT TAKE YAZ or ORAL CONTRACEPTIVES
Cigarette smoking increases the risk of serious adverse effects on the heart and blood vessels from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should not smoke.
Some women should not use YAZ. For example, you should not take YAZ if you are pregnant or think you may be pregnant. You should also not use YAZ if you have had any of the following conditions:
In addition, you should not use YAZ if you have any of the following conditions:
Tell your healthcare provider if you have ever had any of the above conditions (Your healthcare provider can recommend another method of birth control). If you are currently on daily, long-term treatment for a chronic condition with any of the following medications, you should consult your healthcare provider before taking YAZ:
Tell your healthcare provider if you have or ever had:
Women with any of these conditions should be checked often by their healthcare provider if they choose to use oral contraceptives. Also, be sure to inform your doctor or healthcare provider if you smoke, are on any medications, recently had a baby or miscarriage, or are breast feeding.
All methods of birth control and pregnancy are associated with a risk of developing certain diseases which may lead to disability or death. An estimate of the number of deaths associated with different methods of birth control and pregnancy has been calculated and is shown in the following table.
ANNUAL NUMBER OF BIRTH-RELATED OR METHOD-RELATEDDEATHS ASSOCIATED WITH CONTROL OF FERTILITY PER100,000 NONSTERILE WOMEN, BY FERTILITY-CONTROLMETHOD ACCORDING TO AGE
| Method of Control and Outcome | 15-19 | 20-24 | 25-29 | 30-34 | 35-39 | 40-44 |

| \1\ Deaths are birth related \2\ Deaths are method related Adapted from H.W. Ory, Family Planning Perspectives, 15:57-63, 1983. |
||||||
In the above table, the risk of death from any birth control method is less than the risk of childbirth, except for oral contraceptive users over the age of 35 who smoke and pill users over the age of 40 even if they do not smoke. It can be seen in the table that for women aged 15 to 39, the risk of death was highest with pregnancy (7-26 deaths per 100,000 women, depending on age). Among pill users who do not smoke, the risk of death was always lower than that associated with pregnancy for any age group, except for those women over the age of 40, when the risk increases to 32 deaths per 100,000 women, compared to 28 associated with pregnancy at that age. However, for pill users who smoke and are over the age of 35, the estimated number of deaths exceeds those for other methods of birth control. If a woman is over the age of 40 and smokes, her estimated risk of death is four times higher (117/100,000 women) than the estimated risk associated with pregnancy (28/100,000 women) in that age group.
The suggestion that women over 40 who do not smoke should not take oral contraceptives is based on information from older high-dose pills and on less-selective use of pills than is practiced today. An Advisory Committee of the FDA discussed this issue in 1989 and recommended that the benefits of oral contraceptive use by healthy, non-smoking women over 40 years of age may outweigh the possible risks. However, all women, especially older women, are cautioned to use the lowest-dose pill that is effective.
If any of these adverse effects occur while you are taking oral contraceptives, call your doctor immediately:
INSTRUCTIONS TO PATIENTS
HOW TO TAKE THE PILL
IMPORTANT POINTS TO REMEMBER BEFORE YOU START TAKING YOUR PILLS:
BEFORE YOU START TAKING YOUR PILLS
 |
WHEN TO START THE FIRST PACK OF PILLS
You have a choice for which day to start taking your first pack of pills. Decide with your healthcare provider which is the best day for you. Pick a time of day which will be easy to remember.
DAY 1 START:
SUNDAY START:
WHEN YOU SWITCH FROM A DIFFERENT BIRTH CONTROL PILL
When switching from another birth control pill, YAZ should be started on the same day that a new pack of the previous birth control pill would have been started.
WHAT TO DO DURING THE MONTH
WHAT TO DO IF YOU MISS PILLS If you MISS 1 light pink "active" pill:
If you MISS 2 light pink "active" pills in a row in WEEK 1 OR WEEK 2 of your pack:
If you MISS 2 light pink "active" pills in a row in WEEK 3 or Week 4 of your pack:
If you MISS 3 OR MORE light pink "active" pills in a row during ANY Week:
If you MISS ANY of the 4 white "reminder" pills in Week 4: THROW AWAY the pills you missed. Keep taking one pill each day until the pack is empty. You do not need a back-up method.
FINALLY, IF YOU ARE STILL NOT SURE WHAT TO DO ABOUT THE PILLS YOU HAVE MISSED:
Use a BACK-UP METHOD (such as condoms or spermicides) anytime you have sex.
KEEP TAKING ONE ACTIVE LIGHT PINK PILL EACH DAY until you contact your healthcare provider.
PREGNANCY AFTER STOPPING THE PILL
There may be some delay in becoming pregnant after you stop using oral contraceptives, especially if you had irregular menstrual cycles before you used oral contraceptives. It may be advisable to postpone conception until you begin menstruating regularly once you have stopped taking the pill and desire pregnancy. There does not appear to be any increase in birth defects in new-born babies when pregnancy occurs soon after stopping the pill.
OVERDOSAGE
Serious ill effects have not been reported following ingestion of large doses of other oral contraceptives by young children. Overdosage of YAZ may cause nausea and withdrawal bleeding in females and may increase blood levels of potassium or decrease blood levels of sodium, which could be dangerous. In case of over-dosage, contact your healthcare provider.
OTHER INFORMATION
Your healthcare provider will take a medical and family history before prescribing oral contraceptives and will examine you. The physical examination may be delayed to another time if you request it and the healthcare provider believes that it is appropriate to postpone it. You should be re-examined at least once a year. Be sure to inform your healthcare provider if there is a family history of any of the conditions listed previously in this leaflet. Be sure to keep all appointments with your healthcare provider, because this is a time to determine if there are early signs of side effects of oral contraceptive use. Do not use the drug for any condition other than the one for which it was prescribed. This drug has been prescribed specifically for you; do not give it to others who may want birth control pills.
HEALTH BENEFITS FROM ORAL CONTRACEPTIVES
In addition to preventing pregnancy, use of oral contraceptives may provide certain benefits. They are:
If you want more information about birth control pills, ask your doctor or pharmacist. They have a more technical leaflet called the Prescribing Information which you may wish to read.

ETHINYL ESTRADIOL/DROSPIRENONE - ORAL
(ETH-in-il ess-tra-DYE-ole/droh-SPYE-re-none)
COMMON BRAND NAME(S): Yasmin 28
WARNING: Smoking cigarettes/using tobacco while using hormonal birth control (pill/patch/ring) increases your risk of heart problems and stroke. Do not smoke. The risk of heart problems increases with age (especially in women over 35) and with frequent smoking (15 or more cigarettes a day).
USES: This medication is used to prevent pregnancy. It contains 2 hormones (drospirenone, a progestin, and ethinyl estradiol, an estrogen). These hormones prevent pregnancy by preventing the release of an egg (ovulation). They also change the womb and cervical mucus, making it more difficult for an egg to meet sperm (fertilization) or for the fertilized egg to attach to the wall of the womb (implantation).
Besides preventing pregnancy, birth control pills have been shown to help make your periods more regular, decrease blood loss and painful periods (dysmenorrhea), and decrease your risk of ovarian cysts.
Use of this medication does not protect you or your partner against sexually transmitted diseases (e.g., HIV, gonorrhea, chlamydia).
HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using this product and each time you get a refill. The leaflet contains very important information on when to take your pills and what to do if you miss a dose. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth once daily or as directed by your doctor. Pick a time of day that is easy for you to remember, and take your pill at the same time each day.
It is very important to continue taking this medication exactly as prescribed by your doctor. Follow the package instructions to find the first tablet, start with the first tablet in the pack, and take them in the correct order. Do not skip any doses. Pregnancy is more likely if you miss pills, start a new pack late, or take your pill at a different time of the day than usual.
Taking this medication after your evening meal or at bedtime may help if you have stomach upset or nausea with the medication. You may choose to take this medication at another time of day that is easier for you to remember. No matter what dosing schedule you use, it is very important that you take this medication at the same time each day, 24 hours apart. Ask your doctor or pharmacist if you have any questions.
Your pill pack contains 21 pills with active medication. It may also contain 7 reminder pills with no medication. Take one active pill (with hormones) once daily for 21 days in a row. If you are using a product with 28 tablets, take an inactive pill once daily for 7 days in a row after you have taken the last active pill unless otherwise directed by your doctor. If you are using a product with 21 tablets, do not take any tablets for 7 days unless otherwise directed by your doctor. You should have your period during the fourth week of the cycle. After you have taken the last inactive tablet in the pack or gone 7 days without taking an active tablet, start a new pack the next day whether or not you have your period. If you do not get your period, consult your doctor.
If this is the first time you are using this medication and you are not switching from another form of hormonal birth control (e.g., patch, other birth control pills), take the first tablet in the pack on the first Sunday following the beginning of your menstrual period or on the first day of your period. If your period begins on a Sunday, begin taking this medication on that day. For the first cycle of use only, use an additional form of non-hormonal birth control (e.g., condoms, spermicide) for the first 7 days to prevent pregnancy until the medication has enough time to work. If you start on the first day of your period, you do not need to use back-up birth control the first week.
Ask your doctor or pharmacist for information about how to switch from other forms of hormonal birth control (e.g., patch, other birth control pills) to this product. If any of this information is unclear, consult the Patient Information Leaflet or your doctor or pharmacist.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these serious side effects occur: changes in vaginal bleeding (e.g., continuous spotting, sudden heavy bleeding, missed periods), problem wearing contact lenses, dark patches on the skin (melasma), unwanted facial/body hair, swelling of the ankles/feet, weight changes (gain or loss).
This medication may rarely cause serious (sometimes fatal) problems from blood clots (e.g., pulmonary embolism, stroke, heart attack). Seek immediate medical attention if you experience: sudden shortness of breath, chest/jaw/left arm pain, confusion, coughing up blood, sudden dizziness/fainting, pain/swelling/warmth in the groin/calf, tingling/weakness/numbness in the arms/legs, headaches that are different from those you may have experienced in the past (e.g., headaches with other symptoms such as vision changes/lack of coordination, existing migraines becoming worse, sudden/very severe headaches), slurred speech, weakness on one side of the body, vision problems/changes.
Tell your doctor immediately if any of these rare but very serious side effects occur: lumps in the breast, severe stomach/abdominal/pelvic pain, mental/mood changes (e.g., depression, suicidal thoughts, persistent trouble sleeping), unusual tiredness, dark urine, yellowing eyes/skin.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction include: rash, itching, swelling, severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
