Originally designed as an antidepressant, Addyi was repurposed for women who have not gone through menopause and have a low sexual desire. Addyi – generic name Flibanserin – can be used in cases where the cause of low sexual desire is not related to medical disorders, mood or psychiatric disorders or as a side effect from other medications or drugs. Addyi is not a sexual performance enhancer nor should it be used to treat relationship problems. Women who have already gone through menopause should not use Addyi, nor is it suitable for use by men. The causes of low sexual desire in cases treatable with Addyi are likely complicated and certainly not well known. Brain neurotransmitter levels (dopamine, serotonin, norepinephrine) likely have a strong influence.
