Addyi (Flibanserin) belongs to the class of medications called central nervous system agents. It is used to treat a condition called hypoactive sexual desire disorder (HSDD). Addyi (Flibanserin) is intended for use by women who have not yet experienced Menopause and who have had a low sexual desire 75 to 100 per cent of the time, for a minimum of 6 months, and this low sexual desire is causing distress or problems with intimate relationships.

The exact way that Addyi (Flibanserin) works is not known. It is believed to affect the levels of dopamine and serotonin in the brain. These chemicals are involved in sexual interest and desire. Addyi (Flibanserin) does not improve sexual performance.
