Sarafem

Sarafem (fluoxetine hydrochloride) is a prescription medication specifically indicated for the treatment of Premenstrual Dysphoric Disorder (PMDD), a severe form of premenstrual syndrome. It belongs to the class of drugs known as selective serotonin reuptake inhibitors (SSRIs) and works by restoring the balance of serotonin, a natural substance in the brain that helps maintain mental balance. This medication is designed to provide significant relief from the intense emotional and physical symptoms that can severely disrupt a woman’s daily life in the luteal phase of her menstrual cycle. By targeting the core neurochemical imbalance associated with PMDD, Sarafem offers a clinically proven, non-hormonal therapeutic option for managing this debilitating condition.

Features

• Active ingredient: Fluoxetine Hydrochloride
• Standard dosage forms: 10 mg and 20 mg capsules
• Pharmacological class: Selective Serotonin Reuptake Inhibitor (SSRI)
• Specifically approved by the FDA for the treatment of Premenstrual Dysphoric Disorder (PMDD)
• Available by prescription only
• Can be administered in intermittent (luteal phase) or continuous dosing regimens

Benefits

• Provides significant reduction in the severity of emotional symptoms such as irritability, tension, sudden mood swings, and feeling overwhelmed.
• Alleviates physical symptoms associated with PMDD, including breast tenderness, bloating, and headaches.
• Improves overall daily functioning, social interactions, and quality of life during the symptomatic phase of the menstrual cycle.
• Offers a non-hormonal treatment alternative for women who cannot or prefer not to use oral contraceptives or other hormonal therapies.
• The option for luteal-phase dosing (approximately 14 days before menses) can minimize overall medication exposure while maintaining efficacy.

Common use

Sarafem is primarily and exclusively used for the management of Premenstrual Dysphoric Disorder (PMDD). PMDD is a severe, clinically distinct condition that goes beyond typical premenstrual syndrome (PMS). It is characterized by a constellation of severe emotional and physical symptoms—such as marked anger, irritability, anxiety, depressed mood, difficulty concentrating, lethargy, and appetite changes—that occur consistently during the last week of the luteal phase in most menstrual cycles. These symptoms begin to remit within a few days of the onset of menses and are absent in the week post-menses. The diagnosis must be confirmed by prospective daily ratings for at least two symptomatic cycles. Sarafem is not intended for general PMS or for other conditions, though its active ingredient, fluoxetine, is used in other formulations for major depressive disorder, OCD, and panic disorder.

Dosage and direction

The dosage of Sarafem must be individualized and initiated under the direct supervision of a physician.

• Initial Dose: The recommended starting dose for PMDD is 20 mg per day, taken orally.
• Dosing Regimens: Sarafem may be administered either continuously (every day throughout the month) or intermittently (only during the luteal phase of the menstrual cycle, i.e., starting 14 days before the anticipated onset of menstruation).
• Dose Adjustment: Based on individual patient response and tolerability, a physician may consider increasing the dose after several cycles. Doses above 60 mg/day have not been systematically evaluated in PMDD patients.
• Administration: Capsules should be swallowed whole and can be taken with or without food. To avoid potential insomnia, it is often recommended to take the dose in the morning.
• Duration: It may take several menstrual cycles to observe the full therapeutic benefit. Treatment should be re-evaluated periodically to assess the need for continued therapy.

Precautions

• Clinical Worsening and Suicide Risk: Patients, especially children, adolescents, and young adults, treated with antidepressants may experience worsening of depression or the emergence of suicidal ideation and behavior. Close monitoring for clinical worsening, suicidality, or unusual changes in behavior is essential, especially during initial months of therapy and after dose changes.
• Serotonin Syndrome: There is a potential for life-threatening serotonin syndrome, particularly with concomitant use of other serotonergic drugs. Symptoms include mental status changes, autonomic instability, neuromuscular aberrations, and gastrointestinal symptoms.
• Abnormal Bleeding: SSRIs may increase the risk of bleeding events. Patients should be cautioned about this risk, especially when taking Sarafem concomitantly with aspirin, NSAIDs, warfarin, or other anticoagulants.
• Activation of Mania/Hypomania: Sarafem may precipitate a manic episode in patients with bipolar disorder. Patients should be screened for bipolar disorder before initiation, as treating such patients with an antidepressant alone can increase this risk.
• Seizures: Sarafem should be introduced with caution in patients with a history of seizures.
• Discontinuation Syndrome: Abrupt discontinuation can lead to symptoms such as dizziness, sensory disturbances, anxiety, irritability, agitation, insomnia, and lethargy. A gradual dose reduction is recommended when discontinuing therapy.
• Pregnancy and Nursing: Use during pregnancy and nursing should only be considered if the potential benefit justifies the potential risk to the fetus or infant. A physician must be consulted.

Contraindications

Sarafem is contraindicated in the following scenarios:

• Patients taking monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping an MAOI due to the risk of serious, sometimes fatal, drug interactions. Similarly, an MAOI should not be started within 5 weeks of discontinuing Sarafem.
• Patients taking pimozide or thioridazine.
• Patients with a known hypersensitivity to fluoxetine hydrochloride or any of the inactive ingredients in the formulation.

Possible side effect

Like all medications, Sarafem can cause side effects, though not everyone experiences them. Common side effects are often transient and may include:

• Headache, nervousness, insomnia, drowsiness, fatigue
• Nausea, diarrhea, dry mouth, dyspepsia
• Sweating, rash
• Asthenia (weakness)
• Sexual dysfunction (e.g., anorgasmia, decreased libido)

Less common but more serious side effects require immediate medical attention. These include:

• Signs of an allergic reaction (hives, difficulty breathing, swelling of face/tongue/throat)
• Signs of serotonin syndrome (agitation, hallucinations, fever, fast heart rate, muscle stiffness, nausea/vomiting/diarrhea, loss of coordination)
• Easy bruising or unusual bleeding
• Worsening depression, suicidal thoughts, unusual behavior
• Seizures (convulsions)
• Vision changes, eye pain or swelling
• Manic episodes (racing thoughts, increased energy, reckless behavior, extreme happiness)

Drug interaction

Sarafem has a significant potential for drug interactions due to its potent inhibition of the CYP2D6 liver enzyme system. It is crucial to inform your physician of all medications you are taking, including prescription, over-the-counter, vitamins, and herbal products.

• MAO Inhibitors (Isocarboxazid, Linezolid, Methylene Blue, Phenelzine, Rasagiline, Selegiline, Tranylcypromine): Contraindicated. Risk of serious, potentially fatal serotonin syndrome.
• Other Serotonergic Drugs (Tramadol, Triptans, TCAs, Fentanyl, Lithium, Tryptophan, St. John’s Wort): Increased risk of serotonin syndrome.
• Drugs Metabolized by CYP2D6 (Tricyclic Antidepressants, Antipsychotics like Risperidone and Thioridazine, Type 1C Antiarrhythmics): Sarafem may significantly increase the plasma concentrations of these drugs, increasing the risk of adverse effects. Thioridazine and pimozide are contraindicated.
• Anticoagulants (Warfarin) and NSAIDs (Ibuprofen, Naproxen): Increased risk of bleeding.
• Drugs Highly Protein-Bound (Warfarin, Digoxin): Sarafem may displace other drugs from protein binding sites, potentially increasing their activity.

Missed dose

• If a dose is missed, it should be taken as soon as it is remembered.
• However, if it is almost time for the next scheduled dose, the missed dose should be skipped, and the regular dosing schedule resumed.
• Do not take a double dose to make up for a missed one, as this increases the risk of side effects.

Overdose

In case of overdose, contact a poison control center or emergency room immediately. Symptoms of overdose may include:

• Nausea and vomiting
• Agitation, restlessness, delirium
• Seizures
• Drowsiness, coma
• Tachycardia (fast heart rate) and other cardiac arrhythmias
• Other signs of serotonin syndrome There is no specific antidote for Sarafem overdose. Treatment consists of providing supportive care and managing symptoms. Gastric lavage and administration of activated charcoal may be considered.

Storage

• Store Sarafem capsules at room temperature, between 20°C to 25°C (68°F to 77°F).
• Keep the medication in its original container, tightly closed, and out of reach of children and pets.
• Protect from light and moisture.
• Do not store in the bathroom or other damp places.
• Safely dispose of any expired or unused medication. Do not flush down the toilet. Consult a pharmacist on proper disposal methods.

Reviews

• “As a practicing gynecologist for over 20 years, introducing Sarafem for appropriate patients with severe, prospectively-confirmed PMDD has been transformative. The luteal-phase dosing option is particularly appreciated by my patients, offering efficacy with a reduced side effect burden compared to continuous SSRI use.” – Board-Certified OB/GYN, Northeast US
• “The targeted mechanism of Sarafem addresses the core serotonergic dysfunction we see in PMDD. In my clinical trials unit, we observed a statistically significant and clinically meaningful reduction in both the emotional and physical symptom clusters on the DRSP scale compared to placebo. It remains a cornerstone of our non-hormonal treatment algorithm.” – Principal Investigator, Clinical Research
• “From a psychiatric perspective, the importance of patient selection cannot be overstated. Sarafem is not for simple PMS. For the subset of women meeting strict DSM-5 criteria for PMDD, it is one of the most effective evidence-based tools we have to restore function and quality of life during the luteal phase.” – Reproductive Psychiatrist, Academic Medical Center
