Flibanserin: A detailed review of the "Female Viagra" for Libido
Flibanserin (brand names Addyi, Fliban, etc.) is a medication often mistakenly referred to as "Female Viagra." However, its mechanism of action is fundamentally different from male erection drugs. Flibanserin is the world's firstdrug approved by the FDA (U.S. Food and Drug Administration) specifically for the treatment of Hypoactive Sexual Desire Disorder (HSDD) in premenopausal women.
What is Flibanserin and its purpose?
Flibanserin is a medication indicated for the treatment of HSDD (also known as low libido), which is characterized by a persistent or recurrent absence of sexual thoughts, fantasies, and desire, causing personal distress or interpersonal difficulties for the woman.
1. Indication and Target Audience
The drug is indicated exclusively for treating this condition in women for whom:
-
The low libido is not caused by medical conditions (e.g., hormonal imbalance), psychiatric disorders (depression), or relationship problems.
-
The low libido causes stress and dissatisfaction.
2. Key Difference from Sildenafil (Viagra)
-
Viagra (Sildenafil): This is a vascular drug (a PDE5 inhibitor). It increases blood flow to the genitals, improving physical arousal (lubrication, sensitivity). It does not affect desire.
-
Flibanserin (Fliban): This is a neuromodulator. It acts on brain chemistry, attempting to restore sexual desire(libido) itself.
Detailed mechanism of action of Flibanserin
Flibanserin is not an instant stimulant or aphrodisiac. It works by restoring the balance of neurotransmitters (chemical messengers) in the brain that regulate sexual desire:
-
Decreases Serotonin (Inhibition): It acts as an agonist at the 5-HT1A receptor and an antagonist at the 5-HT2A receptor. This leads to a decrease in the level of serotonin, which often "suppresses" sexual desire.
-
Increases Dopamine and Norepinephrine (Excitation): Simultaneously, the drug increases the levels of dopamine and norepinephrine – neurotransmitters responsible for motivation, pleasure, and arousal.
Key takeaway: Flibanserin is NOT an "on-demand" pill. You cannot take it an hour before sex and get results. It is a course-based medication.
Instructions for use: Course-based intake
To achieve a therapeutic effect, Flibanserin requires accumulation in the body.
-
Dosage: 100 mg (one tablet).
-
Frequency of Intake: Strictly once daily, at bedtime.
-
Why at bedtime? Taking the drug during the day can cause severe dizziness, drowsiness, and hypotension (drop in blood pressure). Taking it at night minimizes these risks.
-
Course: The effect develops gradually. The first improvements may be seen after 3-4 weeks. The maximum effect is achieved after 6-8 weeks of daily intake. If there is no effect after 8 weeks, intake should be discontinued.
Critical contraindications and risks
Flibanserin has very strict limitations due to the risk of serious side effects.
-
ALCOHOL: ABSOLUTELY FORBIDDEN! Concomitant use of Flibanserin and alcohol (even in small amounts) can cause severe hypotension (dangerous drop in blood pressure) and syncope (fainting).
-
Drug Interactions: Forbidden to take with:
-
Potent CYP3A4 Inhibitors: (Ketoconazole, Itraconazole, Erythromycin, Grapefruit juice). They sharply increase the concentration of Flibanserin, increasing the risk of fainting.
-
MAO Inhibitors (MAOIs): Risk of serotonin syndrome.
-
Other CNS depressants (sleeping pills, tranquilizers).
-
-
Liver Disease: Contraindicated in any form of hepatic impairment.
Side effects of Flibanserin
The most common side effects (especially with daytime dosing):
-
Dizziness.
-
Drowsiness, fatigue.
-
Nausea.
-
Dry mouth.
-
Fainting (syncope) – especially when combined with alcohol.
Professional advice on using
-
This is not Viagra: Flibanserin treats desire (libido). If you have desire but lack physical arousal (dryness, low sensitivity), you need Sildenafil-based drugs (Lovegra) or Tadalafil-based drugs (Tadadel FM).
-
Doctor consultation is necessary: Before taking, a consultation with a gynecologist and/or sexologist is required to rule out other causes of low libido (depression, hormonal imbalance, relationship issues).
-
Patience: The drug's effect develops slowly. Do not expect results in the first week.

-
How long does Flibanserin last? It is a course-based drug. It works 24/7 while you are taking it by maintaining a neurochemical balance.
-
Can I take Flibanserin if I drink a glass of wine? No. Even one glass of wine combined with Flibanserin can cause fainting.
