Imitrex is a prescription drug used for the treatment of migraine headaches once they start. The drug does not help prevent migraines. A migraine occurs when some of the blood vessels in the head become dilated. This medication works by narrowing these blood vessels, helping return them to their normal state. Tingling, dizziness, and chest discomfort are a few common side effects of this drug. Imitrex -- which comes in a tablet form, a nasal spray, and an injection -- should be taken only during a migraine, not on a regular basis.
