Dosage Forms and Strengths of Flibanserin

Tablet: 100 mg

How to Take Flibanserin: Administration Instructions

Flibanserin should be taken once daily at bedtime to minimize the risk of side effects such as dizziness or low blood pressure. It is important to avoid alcohol while using this medication, as combining the two can significantly increase the risk of severe low blood pressure and fainting. If you miss a dose, skip it and take your next dose at the usual time. Do not double your dose to make up for a missed one.

Flibanserin Side Effects and Adverse Reactions

As with any medication, Flibanserin may cause side effects. These can range from mild to serious and include the following:

1. Dizziness: This is a common side effect, particularly when standing up quickly.
2. Low Blood Pressure (Hypotension): The risk increases if Flibanserin is taken with alcohol.
3. Fatigue: Some individuals may feel unusually tired or weak.
4. Nausea: Stomach discomfort or nausea may occur in some patients.
5. Fainting (Syncope): Although rare, fainting can occur, especially when Flibanserin is combined with alcohol or medications that lower blood pressure.

Contraindications for Flibanserin

A contraindication refers to a specific condition or circumstance in which a medication should not be used because it may cause harm. Understanding these contraindications is crucial before beginning any new treatment. Below are the key contraindications for Flibanserin, a medication used to treat female sexual dysfunction.

Alcohol use: Flibanserin must not be taken with alcohol, as this combination can lead to dangerously low blood pressure (hypotension) and fainting (syncope). The interaction significantly increases these risks, making it unsafe to consume alcohol while using this medication.

Liver impairment: Flibanserin is contraindicated for individuals with liver dysfunction. A compromised liver may be unable to process the medication effectively, which can result in heightened side effects or toxic levels of the drug in the body.

Use of certain medications: Flibanserin should not be taken alongside drugs that strongly inhibit the enzyme CYP3A4. These medications can cause Flibanserin levels in the body to rise to unsafe levels, increasing the likelihood of severe side effects. Examples include certain antifungal agents, antibiotics, and medications used to treat HIV (see Drug to Drug Interactions below).

Drug to Drug Interactions with Flibanserin

Flibanserin can interact with other medications, which may either amplify its side effects or reduce its effectiveness as a treatment for low sexual desire. Below are some medications known to interact with Flibanserin:

1. Ketoconazole (Nizoral): This antifungal medication can significantly increase Flibanserin levels in the body, raising the risk of adverse effects.
2. Ritonavir (Norvir): A potent CYP3A4 inhibitor used in HIV treatment, Ritonavir can cause dangerously high concentrations of Flibanserin in the bloodstream.
3. Clarithromycin (Biaxin): This antibiotic can elevate Flibanserin levels, increasing the likelihood of side effects such as low blood pressure and fainting.
4. Verapamil (Calan, Verelan): A medication used to treat heart conditions, Verapamil can interact with Flibanserin, heightening the risk of adverse reactions.

Flibanserin and Pregnancy

Is it safe to take Flibanserin during pregnancy?

Currently, there is limited research on the safety of Flibanserin during pregnancy. As a precaution, its use is generally not recommended for pregnant individuals. If you are pregnant or planning to become pregnant, it is important to consult your healthcare provider to discuss safer alternatives. For tailored advice on managing female sexual dysfunction during pregnancy, consider scheduling a telemedicine consultation with one of our providers.

Flibanserin while Breastfeeding

Is it safe to take Flibanserin while breastfeeding?

There is not enough information to determine whether Flibanserin passes into breast milk or if it could affect a nursing infant. Due to this uncertainty, it is generally advised to avoid using Flibanserin while breastfeeding. If you are considering this medication while nursing, consult your healthcare provider to carefully weigh the potential risks and benefits. You may also book a telemedicine appointment with one of our providers for expert guidance on treatment options for hypoactive sexual desire disorder.

Estimated Cost of Flibanserin Medication

The cost of a 30-day supply of Flibanserin (100 mg tablets, taken once daily) without insurance typically ranges between $400 and $500. However, using a GoodRx coupon can significantly reduce this expense to approximately $30 to $50 for the same supply. Keep in mind that prices may vary depending on the pharmacy and your location.

Possible Alternatives to Flibanserin

If Flibanserin is not the right option for you, there are other treatments and lifestyle changes that may address the conditions it is prescribed for. It is essential to consult your healthcare provider before making any changes to your treatment plan. You can also connect with one of our telemedicine providers to explore these alternatives.

Alternatives for Hypoactive Sexual Desire Disorder (HSDD)

Other potential options include counseling, lifestyle adjustments such as stress management, or medications like bremelanotide (Vyleesi).

Options for Sexual Dysfunction

Improving underlying physical or psychological factors, such as stress or relationship challenges, can often alleviate symptoms. Hormone therapy or alternative medications may also be effective solutions.

Treatments for Female Sexual Arousal Disorder

Therapies such as counseling, pelvic floor exercises, or hormone therapy may help. Discuss these options with your healthcare provider to determine the most suitable approach for your needs.

Managing Depression

For depression, treatments like antidepressants (e.g., SSRIs such as sertraline or fluoxetine) or therapy may be more appropriate and effective.

Addressing Anxiety

Managing anxiety may involve cognitive-behavioral therapy (CBT), mindfulness techniques, or medications such as benzodiazepines or SSRIs. Your healthcare provider can help identify the best approach for you.

Stress Management Techniques

Incorporating stress management strategies like meditation, regular physical activity, and therapy can improve overall well-being and reduce stress-related symptoms.

Resolving Relationship Issues

Couples therapy or individual counseling can help address relationship challenges that may be affecting sexual desire or intimacy.

Hormonal Imbalance Solutions

For hormonal imbalances, treatments such as hormone replacement therapy (HRT) or lifestyle changes, including a nutritious diet and consistent exercise, may help restore balance.

Managing Menopause Symptoms

To alleviate menopause-related symptoms like low libido, options include hormone replacement therapy (HRT), lifestyle modifications, or non-hormonal medications. Consult your healthcare provider to determine the best course of action.

Other Treatments for Sexual Desire Disorder

Depending on the underlying cause, other medications, therapy, or lifestyle adjustments may be effective in managing sexual desire disorders. Your healthcare provider can guide you in exploring these options.
