A migraine causes the blood vessels in the brain to expand. It also causes a release of chemicals in the brain that can cause inflammation (swelling and irritation). Sumatriptan works by helping to bring your blood vessels back to their normal size. It also helps prevent your body’s release of these chemicals that cause inflammation.

Sumatriptan oral tablet may cause drowsiness. It may also cause other side effects.
