Sumatriptan

Sumatriptan

What is sumatriptan?

Sumatriptan oral tablet is a prescription drug that's available as the brand-name drug Imitrex. It's also available as a generic drug. Generic drugs usually cost less. In some cases, they may not be available in every strength or form as the brand-name version.

Sumatriptan also comes in a nasal spray, an injectable solution, or a nasal powder.

How it works

Sumatriptan belongs to a class of drugs called serotonin-1 receptor agonists. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

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.
