Patients should be counseled that oral contraceptives do not protect against transmission of HIV (AIDS) and other sexually transmitted diseases (STDs) such as chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis.
Each Opill tablet contains 0.075 mg of a single active steroid ingredient, norgestrel, a totally synthetic progestogen. Norgestrel is designated as ()-13-Ethyl-17-hydroxy-18,19-dinor-17a-pregn-4-en-20-yn-3-one and is included in the formulation as a racemate. The inactive ingredients present are cellulose, FD&C Yellow 5, lactose, magnesium stearate, and polacrilin potassium.
Opill Tablets are indicated for use by females of reproductive potential to prevent pregnancy.
Opill Tablets are not for use as emergency contraception.
In eight US clinical studies with Opill Tablets, 2,173 women completed at least one cycle and 648 completed at least 13 cycles providing a total of 21,856 28-day cycles of exposure in women aged from 15 to 49 years. The racial demographic was 53% Caucasian and 47% African-American. The pregnancy rate was approximately 2 per 100 women-years.
DOSAGE AND ADMINISTRATION
To achieve maximum contraceptive effectiveness, Opill Tablets must be taken exactly as directed. The woman should take one tablet every day, at the same time. Administration is continuous, with no interruption between pill packs. See PATIENT LABELING for detailed instructions.
Opill Tablets (0.075 mg norgestrel) are available in a blister package of 28 tablets as follows: NDC 76336-457-28 , yellow, round tablet debossed “NG75” on one side.
Store at controlled room temperature between 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature].
Manufactured for: Laboratoire HRA Pharma, 15 rue Béranger – 75003, Paris, France. Revised: Aug 2017
- Delayed follicular atresia/ovarian cysts
- Menstrual irregularity, changes in menstrual flow; breakthrough bleeding/spotting; amenorrhea, prolonged bleeding
The following adverse reactions were reported in ≥ 5% of subjects in the Opill Tablet clinical studies:
- Increased appetite
- Abdominal pain, cramps and bloating
- Vaginal discharge
- Breast discomfort
- The effectiveness of progestin-only pills is reduced by
hepatic enzyme-inducing drugs such as phenytoin, carbamazepine, barbiturates,
rifampin, efavirenz, bosentan and herbal preparations containing St. John's
Wort (hypericum perforatum). This could result in unintended pregnancy or
During concomitant use of Opill and substances that may affect its efficacy, it is recommended that a nonhormonal back-up method of contraception (such as condom) be used in addition to the regular intake of Opill Tablets. Use of a nonhormonal back-up method is recommeded for 28 days after discontinuation of substances that have led to induction of hepatic microsomal enzymes. For women receiving long-term therapy with hepatic enzyme inducers, another method of contraception should be considered.
- Effectiveness of progestin-containing hormonal
contraceptives and emergency contraceptive ulipristal acetate may be decreased
if progestin-containing hormonal contraceptives are used within five days after
ulipristal acetate dosing.
If a woman wishes to use Opill Tablets after using ulipristal acetate, she should do so no sooner than 5 days after the intake of ulipristal acetate and she should use a reliable barrier method for subsequent acts of intercourse until her next menstrual period. Consult the product information of concomitant medications/substances to identify potential interactions.
Diarrhea and/or vomiting within 4 hours after taking a pill may reduce hormone absorption. Women should use of a nonhormonal back-up method of birth control (such as a condom or spermicide) during the next 48 hours.
Interactions With Laboratory Tests
The following endocrine tests may be affected by Opill Tablets use:
- Sex hormone-binding globulin (SHBG) concentrations may be decreased.
- Total thyroxine concentrations may be decreased, due to a decrease in thyroid binding globulin (TBG). However, free thyroxine level should remain unchanged.
FD &C Yellow No. 5
Opill Tablets contains FD&C Yellow No.5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons. Although the overall incidence of FD&C Yellow No. 5 (tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity. (See CONTRAINDICATIONS)
Carbohydrate And Lipid Effects
Some Opill Tablets users may experience slight changes in glucose tolerance with increases in plasma insulin, but women with diabetes mellitus who use progestin-only oral contraceptives do not generally experience changes in their insulin requirements.
Lipid metabolism is occasionally affected in that HDL1, HDL2, and apolipoprotein A-I and A-II may be decreased; hepatic lipase may be increased. There is usually no effect on total cholesterol, HDL3, LDL, or VLDL.
The effect of progestin-only oral contraceptives on carbohydrate and lipid metabolism is generally not clinically significant.
The incidence of ectopic pregnancies for progestin-only oral contraceptive users is 5 per 1000 woman-years. Up to 10% of pregnancies reported in clinical studies of progestin-only oral contraceptive users are extrauterine. Health-care providers should be alert to the possibility of an ectopic pregnancy in women who become pregnant or complain of lower abdominal pain while on Opill Tablets.
Delayed Follicular Atresia/Ovarian Cysts
If follicular development occurs, atresia of the follicle is sometimes delayed, and the follicle may continue to grow beyond the size it would attain in a normal cycle. Generally these enlarged follicles disappear spontaneously. Often they are asymptomatic; in some cases they are associated with mild abdominal pain, and rarely they may twist or rupture, requiring surgical intervention.
Bleeding Pattern Alterations
Irregular menstrual patterns are common among women using Opill Tablets. Undiagnosed abnormal uterine bleeding should be evaluated before Opill is prescribed (see CONTRAINDICATIONS). In the 8 U.S. clinical trials of Opill Tablets, there were a total of 2,575 enrolled subjects, and approximately half of them experienced some menstrual changes. This was defined in the clinical studies as vaginal bleeding which, in the judgment of the subject, did not have the characteristics of her pre-treatment menstrual periods in duration, amount or appearance. Subjects experienced unscheduled (breakthrough) bleeding (48.6%) and spotting (47.3%) on Opill Tablets. Amenorrhea occurred in 6.1% of subjects in their first cycle and 28.7% of all subjects during the studies. A total of 379 participants (17.4%) discontinued treatment due to side effects; 67.6% of all discontinuations were due to bleeding patterns. Overall, 6.4% of participants discontinued treatment due to breakthrough bleeding and 2.7% due to amenorrhea (n=2,173 subjects who completed at least one cycle).
If uterine bleeding together with the clinical history is suggestive of infection, malignancy, pregnancy, or other conditions, rule out these conditions. If amenorrhea occurs, consider the possibility of pregnancy.
Hepatic Neoplasia/Liver Disease
Discontinue Opill Tablet use if jaundice or acute disturbances of liver function develop. Do not resume use until markers of liver function return to normal and Opill Tablet causation has been excluded.
The onset or exacerbation of migraine, or development of headache with a new pattern that is recurrent, persistent, or severe requires evaluation of the cause because women with migraine may be at increased risk of stroke.
Opill Tablets are contraindicated for use in pregnant women because there is no need for pregnancy prevention in a woman who is already pregnant [see CONTRAINDICATIONS]. Published studies report no harmful effects on fetal development associated with long-term use of contraceptive doses of oral progestins in pregnant women.
Discontinue Opill Tablets if pregnancy is confirmed.
Small amounts of progestin pass into the breast milk, resulting in steroid levels in infant plasma. No adverse effects have been reported on breastfeeding performance or infant health. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Opill Tablets and any potential adverse effects on the breastfed infant from Opill Tablets or from the underlying maternal condition.
Fertility Following Discontinuation
The limited available data do not indicate a significant delay in the return of normal ovulation and fertility following discontinuation of progestin-only oral contraceptives.
Safety and efficacy of Opill Tablets have been established in women of reproductive age, including adolescents as young as 15 years of age, and almost 30% of subjects in the clinical trials who were under 20 years of age. Use of this product before menarche is not indicated.
Opill Tablets has not been studied in postmenopausal women and is not indicated in this population.
Information For The Patient
Advise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION).
- Before prescribing Opill Tablets, advise the patient that:
- Opill Tablets should be taken at the same time every day, including throughout all bleeding episodes.
- She should use a nonhormonal back-up method of contraception (such as condoms or spermicides) for the next 48 hours whenever Opill Tablets are taken 3 or more hours late, or if she has vomiting or diarrhea within 4 hours after taking the pill.
- Use of Opill Tablets may be associated with changes in their normal menstrual bleeding pattern. However, women who miss two periods (or have missed a single period but have missed doses of Opill) or suspect they may be pregnant should take a pregnancy test.
- She should inform her healthcare provider if she develops repeated vaginal postcoital bleeding, prolonged episodes of bleeding, amenorrhea or development of severe abdominal pain.
- Opill Tablets do not protect against HIV infection (AIDS) or other sexually transmitted infections (STIs).
Symptoms of oral contraceptive overdosage may include nausea, vomiting, breast tenderness, dizziness, somnolence (drowsiness/fatigue), and withdrawal bleeding in females. There is no specific antidote and further treatment of overdose, if necessary, is directed to the symptoms.
Opill Tablets is contraindicated for use by women who are known to have the following conditions:
- Known or suspected pregnancy
- Known or suspected carcinoma of the breast, or other progestin-sensitive cancer, now or in the past
- Undiagnosed abnormal uterine bleeding
- Hypersensitivity to any component of this product (see PRECAUTIONS, FD & C Yellow No. 5)
- Benign or malignant liver tumors
- Acute liver disease
Mode Of Action
Progestin-only oral contraceptives such as Opill Tablets prevent conception by suppressing ovulation in approximately half of the cycles in users, thickening the cervical mucus to inhibit sperm penetration, lowering the midcycle LH and FSH peaks, slowing the movement of the ovum through the fallopian tubes, and altering the endometrium.
Serum progestin levels peak about two hours after oral administration, followed by rapid distribution and elimination. By 24 hours after drug ingestion, serum levels are near baseline, making efficacy dependent upon rigid adherence to the dosing schedule. There are large variations in serum levels among individual users. Progestin-only administration results in lower steady-state progestin levels and a shorter elimination half-life than concomitant administration with estrogens.
(norgestrel) Tablets, for Oral Use
Opill does not protect against HIV infection (AIDS) or other sexually transmitted infections (STIs).
What is Opill?
- Opill is a birth control pill for daily use by women to prevent pregnancy.
- Opill tablets are not to be used as emergency contraceptive.
- Opill tablet contain a progestin hormone norgestrel. Progestin-only pills are often called “POPs” or “the minipill.” Opill does not contain estrogen.
How does Opill work?
- Opill prevents pregnancy in several ways. Opill thickens mucus in your cervix, and this change may keep sperm from reaching the egg. Opill stops the release of an egg from your ovary. Opill also thins the lining of your uterus.
How well does Opill work for contraception?
The following chart shows the chance of getting pregnant for women who use different methods of birth control. Each box on the chart contains a list of birth control methods that are similar in effectiveness. The most effective methods are at the top of the chart. The box on the bottom of the chart shows the chance of getting pregnant for women who do not use birth control and are trying to get pregnant.
Opill, a birth control pill, is in the box second to top of the chart.
Do not use Opill if you:
- are or may be pregnant
- have undiagnosed uterine bleeding
- have ever had breast cancer or any other cancer that is sensitive to progestin (a female hormone)

Tell your healthcare provider about all the medicines you take, including prescription and over-the counter medicines, vitamins, and herbal supplements.
How should I take Opill?
- Opill must be taken at the same time every day, so choose a time and then take the pill at that same time every day. If you take a pill late, and especially if you miss a pill, you are more likely to get pregnant (See What if I am late or miss taking OPILL.).
What are some important points to remember when taking Opill?
- You may have some bleeding between periods. Do not stop taking your pills if this happens. Bleeding between periods is usually temporary and does not mean there is a problem; however, if you repeatedly have vaginal bleeding that is brought on by sex or bleeding is prolonged (more than 8 days) or unusually heavy, consult your health-care provider.
- If you have not had a menstrual period for 2 months (or you have missed a single period but you have missed doses of Opill) after you have had regular periods or think you may be pregnant, you should have a pregnancy test.
- If you vomit within 4 hours after taking a pill, or have diarrhea, absorption may not be complete; therefore, use a nonhormonal back-up method of birth control (such as a condom or spermicide) every time you have sex during the next 48 hours.
If you are not sure about how to take Opill, ask your health-care provider.
When can I start Opill?
- You can start taking your first pill on any day, use a non-hormonal back-up method of birth control (such as a condom or spermicide) every time you have sex during the first 48 hours after starting Opill.
- Start the next pack the day after the last pack is finished. There is no break between packs. Always have your next pack of pills ready.
- If you have had a miscarriage or an abortion, you can start Opill the next day. In addition, you should use a non-hormonal back-up method of birth control for the first 48 hours.

- If you switch to Opill tablets from another brand of POPs, you can start the new pack at any time.
What if I want to change from another type of progestin-only method (IMPLANT, INJECTION) or IUD?
- Start taking Opill on the day of an implant or IUD removal or, if using an injection, the day the next injection would be due. In addition, use a non-hormonal back-up method of birth control for the first 48 hours after starting Opill tablets.
What if I am late or miss taking Opill?
If you are late taking a single pill:
- If you are less than 3 hours late from your usual time you take the pill, take 1 pill immediately and go back to taking your pill at your usual time the following day.
- If you are more than 3 hours late
- take 1 pill as soon as you remember and go back to taking your pill at your usual time. This means you may take 2 pills in 1 day.
