Imigran is primarily used to treat acute migraine attacks and is part of a group of medications called serotonin receptor agonists. It works by constricting the blood vessels in the brain that expand during a migraine attack. This medication helps relieve the pain associated with migraines and their annoying symptoms such as nausea, vomiting, and hypersensitivity to light or sound.
Imigran can be effective in treating cluster headaches in some patients and is generally used at the first symptoms of the headache to ensure maximum effectiveness. It is worth noting that it is not a preventive treatment for migraines, but rather is intended to relieve the pain associated with its attacks.
