Sarafem Overview - Patient Information: Side Effects
Nausea, drowsiness, dizziness, anxiety, trouble sleeping, loss of appetite, tiredness, sweating, or yawning may occur. If any of these effects persist or worsen, tell your doctor promptly.
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 right away if any of these unlikely but serious side effects occur: unusual or severe mental/mood changes (such as agitation, unusual high energy/excitement, thoughts of suicide), easy bruising/bleeding, muscle weakness/spasm, shakiness (tremor), decreased interest in sex, changes in sexual ability, unusual weight loss, large pupils.
Get medical help right away if you have any very serious side effects, including: bloody/black/tarry stools, vomit that looks like coffee grounds, fast/irregular heartbeat, fainting, seizures, change in amount of urine, eye pain/swelling/redness, vision changes (such as seeing rainbows around lights at night, blurred vision).
If you have diabetes, fluoxetine may affect your blood sugar levels. Monitor your blood sugar regularly and share the results with your doctor. Your doctor may need to adjust your medication, diet, and exercise when you start or stop fluoxetine.
This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
Rarely, males may have a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and get medical help right away, or permanent problems could occur.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), 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.

Sarafem FDA Prescribing Information: Side Effects
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect or predict the rates observed in practice.
Multiple doses of fluoxetine have been administered to 10,782 patients with various diagnoses in US clinical trials. Adverse reactions were recorded by clinical investigators using descriptive terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse reactions without first grouping similar types of reactions into a limited (that is, reduced) number of standardized reaction categories.
In the tables and tabulations that follow, COSTART Dictionary terminology has been used to classify reported adverse reactions. The stated frequencies represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse reaction of the type listed. A reaction was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. It is important to emphasize that reactions reported during therapy were not necessarily caused by it.
The prescriber should be aware that the figures in the tables and tabulations cannot be used to predict the incidence of side effects in the course of usual medical practice where patient characteristics and other factors differ from those that prevailed in the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from other clinical investigations involving different treatments, uses, and investigators. The cited figures, however, do provide the prescribing physician with some basis for estimating the relative contribution of drug and non drug factors to the side effect incidence rate in the population studied.
Incidence In Placebo-controlled PMDD Clinical Trials
In 1 of 3 placebo-controlled, continuous-dosing trials and 1 placebo-controlled, intermittent-dosing trial of fluoxetine in PMDD, treatment-emergent adverse reactions reporting rates were assessed. The information contained in Table 5 enumerates the most common treatment-emergent adverse reactions associated with the use of SARAFEM 20 mg (incidence of at least 5% for SARAFEM 20 mg and greater than placebo) for the treatment of PMDD and is based on data from the continuous-dosing trial at the recommended dose of SARAFEM (SARAFEM 20 mg, N = 104; placebo, N = 108) and data from the intermittent-dosing trial of fluoxetine in PMDD (SARAFEM 20 mg, N = 86; placebo, N = 88).

Reactions : Incidence in PMDD Placebo- Controlled Clinical Trials
|Body System/Adverse Reaction*||Percentage of Patients Reporting Adverse Reaction|
|SARAFEM 20 mg/day Continuously
(N = 104)
|SARAFEM 20 mg/day Intermittently
(N = 86)
(N = 196)
|Body as a Whole|
|*Included in the table are adverse reactions reported by
at least 5% of patients taking SARAFEM 20 mg either continuously or
intermittently. For additional adverse reaction terms referenced in Warnings
and Precautions, reporting rates for SARAFEM 20 mg continuous and intermittent
were, respectively: anxiety 4 .8%, 1.2% and anorexia 3.8%, 3.5%.
†Thinking abnormal is the COSTART term that captures concentration difficulties.
Incidence In US Depression, OCD, And Bulimia Placebo-Controlled Clinical Trials (Excluding Data From Extensions Of Trials)
Table 6 enumerates the most common treatment-emergent adverse reactions associated with the use of fluoxetine up to 80 mg (incidence of at least 2% for fluoxetine and greater than placebo) in female patients ages 18 to 45 years from US placebo-controlled clinical trials in the treatment of depression, OCD, and bulimia.

back pain, cough increased, depression (includes suicidal thoughts),
dysmenorrhea, flatulence, infection, myalgia, pain, pruritus, rhinitis,
†Thinking abnormal is the COSTART term that captures concentration difficulties. Incidence less than 0.5%.
Adverse Reactions Associated With Discontinuation In Two Placebo-Controlled PMDD Clinical Trials
In a continuous-dosing PMDD placebo-controlled trial, the most common adverse reaction (incidence at least 2% for SARAFEM 20 mg and greater than placebo) associated with discontinuation was nausea (3% for SARAFEM 20 mg, N = 104 and 1% for placebo, N = 108). In an intermittent-dosing placebo controlled trial, no reactions associated with discontinuation reached an incidence of 2% for SARAFEM 20 mg. In these clinical trials, more than one reaction may have been recorded as the cause of discontinuation.
Adverse Reactions Associated With Discontinuation In Depression, OCD, And Bulimia Placebo-Controlled Us Clinical Trials (Excluding Data From Extensions Of Trials)
In female patients age 18 to 45 years in US depression, OCD, and bulimia placebo-controlled clinical trials combined, which collected a single primary reaction associated with discontinuation (incidence at least 1% for fluoxetine and at least twice that for placebo), insomnia (1%, N = 561) was the only reaction reported.
Female Sexual Dysfunction With SSRIs
Although changes in sexual desire, sexual performance, and sexual satisfaction often occur as manifestations of a mood-related disorder, they may also be a consequence of pharmacologic treatment. In particular, some evidence suggests that SSRIs can cause such untoward sexual experiences. Reliable estimates of the incidence and severity of untoward experiences involving sexual desire, performance, and satisfaction are difficult to obtain, however, in part because patients and physicians may be reluctant to discuss them. Accordingly, estimates of the incidence of untoward sexual experience and performance, cited in product labeling, are likely to underestimate their actual incidence. For example, in women (age 18 to 45) receiving fluoxetine for indications other than PMDD, decreased libido was seen at an incidence of 4% for fluoxetine compared with 1% for placebo. There have been spontaneous reports in women (age 18 to 45) taking fluoxetine for indications other than PMDD of orgasmic dysfunction, including anorgasmia.
There are no adequate and well-controlled studies examining sexual dysfunction with fluoxetine treatment. While it is difficult to know the precise risk of sexual dysfunction associated with the use of SSRIs, physicians should routinely inquire about such possible side effects.
Following is a list of all treatment-emergent adverse reactions reported at anytime by females and males taking fluoxetine in all US clinical trials for conditions other than PMDD as of May 8, 1995 (10,782 patients) except (1) those listed in the body or footnotes of Tables 1 or 5 above or elsewhere in labeling; (2) those for which the COSTART terms were uninformative or misleading; (3) those adverse reactions for which a causal relationship to fluoxetine use was considered remote; (4) adverse reactions occurring in only 1 patient treated with fluoxetine and which did not have a substantial probability of being acutely life-threatening; and (5) adverse reactions that could only occur in males.

The following adverse reactions have been identified during post approval use of fluoxetine. Because these reactions are reported voluntarily from a population of uncertain size, it is difficult to reliably estimate their frequency or evaluate a causal relationship to drug exposure.
Voluntary reports of adverse reactions temporally associated with fluoxetine that have been received since market introduction and that may have no causal relationship with the drug include the following: aplastic anemia, atrial fibrillation1, cataract, cerebrovascular accident1, cholestatic jaundice, dyskinesia (including, for example, a case of buccal-lingual-masticatory syndrome with involuntary tongue protrusion reported to develop in a 77-year-old female after 5 weeks of fluoxetine therapy and which completely resolved over the next few months following drug discontinuation), eosinophilic pneumonia1, epidermal necrolysis, erythema multiforme, erythema nodosum, exfoliative dermatitis, gynecomastia, heart arrest1, hepatic failure/necrosis, hyperprolactinemia, hypoglycemia, mmunerelated hemolytic anemia, kidney failure, movement disorders developing in patients with risk factors including drugs associated with such reactions and worsening of pre-existing movement disorders, optic neuritis, pancreatitis1, pancytopenia, pulmonary embolism, pulmonary hypertension, QT prolongation, Stevens-Johnson syndrome, thrombocytopenia1, thrombocytopenic purpura, ventricular tachycardia (including torsades de pointes-type arrhythmias), vaginal bleeding, and violent behaviors .
1These terms represent serious adverse reactions, but do not meet the definition for adverse drug reactions. They are included here because of their seriousness.
