What is Imitrex?
Imitrex (sumatriptan) is a headache medicine that narrows blood vessels around the brain. Imitrex also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.
Imitrex is used to treat migraine headaches. Imitrex will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Imitrex should not be used to treat a common tension headache, a headache that causes loss of movement on one side of your body, or any headache that seems to be different from your usual migraine headaches. Use this medication only if your condition has been confirmed by a doctor as migraine headaches.
