Used primarily to treat hypoactive sexual desire disorder (HSDD) in premenopausal women, flibanserin works by modulating neurotransmitters in the brain, particularly serotonin, to help restore sexual desire. It is taken daily and is intended for those experiencing distress over low libido, where the issue is not caused by underlying medical or psychological conditions. Unlike on-demand treatments, flibanserin requires consistent use to maintain effects. Due to potential side effects like dizziness, fatigue, and hypotension—especially when combined with alcohol—its use is carefully regulated and typically considered after other non-pharmacological approaches have been explored.
