Fliban 100 mg is a medication primarily used to treat hypoactive sexual desire disorder (HSDD) in premenopausal women. The active ingredient in Fliban 100 mg is flibanserin, which is sometimes referred to as the "female Viagra." However, unlike Viagra, which works by increasing blood flow to the genitals, Flibanserin works by affecting neurotransmitters in the brain to increase sexual desire.
