What is levomilnacipran?
Levomilnacipran is a serotonin and norepinephrine reuptake inhibitor antidepressant (SNRI).
Levomilnacipran is used to treat major depressive disorder.
A similar medicine called milnacipran (Savella) is used to treat a chronic pain disorder called fibromyalgia. Levomilnacipran (Fetzima) should not be used to treat fibromyalgia.
Levomilnacipran may also be used for purposes not listed in this medication guide.

Tell your doctor if you also use stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with levomilnacipran could cause a serious condition called serotonin syndrome.
