 Use of Methysergide


Methysergide is a prescription drug formerly used for prophylaxis of cluster headaches/migraine headaches, but is no longer recommended due to retroperitoneal/retropulmonary fibrosis. It is also used in carcinoid syndrome to treat severe diarrhea. It may also be used in the treatment of serotonin syndrome.
