Flibanserin
Summary
Flibanserin is used to treat hypoactive sexual desire disorder (HSDD) in premenopausal women. This is a condition characterized by low sexual desire that causes distress or interpersonal difficulty.
Flibanserin alters the activity of serotonin and other natural substances in the brain to increase sexual desire. It acts as a serotonin receptor 1A agonist and serotonin receptor 2A antagonist.
The usual daily dose for Flibanserin in adults is 100 mg taken once daily at bedtime. It can be taken with or without food.
Common side effects of Flibanserin include dizziness, sleepiness, nausea, and fatigue. Serious adverse effects include severe low blood pressure and fainting, especially when combined with alcohol or certain medications.
Flibanserin should not be used with alcohol, moderate or strong CYP3A4 inhibitors, or in patients with liver problems. It can cause severe low blood pressure and fainting, especially when combined with alcohol or certain medications. It's also not recommended during breastfeeding due to potential serious adverse reactions in a breastfed infant.
