What is levomilnacipran?

Levomilnacipran is a selective 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.

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
