From:
$10.08
Sumatriptan is a prescription serotonin receptor agonist (triptan) used to treat acute migraine attacks and cluster headaches. It works by narrowing blood vessels around the brain and reducing the release of inflammatory substances that trigger migraine pain, nausea, and sensitivity to light or sound. Imitrex does not prevent migraines, but is used to relieve symptoms once a migraine begins.
