Imitrex (Sumatriptan) is used for treating migraine headaches. Sumatriptan belongs to a class of drugs called selective serotonin receptor agonists. This medication works by narrowing blood vessels around the brain. It reduces substances in the body that triggers headache pain, nausea, sensitivity to light and sound, and other migraine symptoms. Imitrex will only treat a headache that has already begun; it will not prevent headaches or reduce the number of attacks.
