Plain-language guide

Sumatriptan, explained by our clinical team

What it is

Sumatriptan was the first triptan and remains the most prescribed. It narrows swollen blood vessels in the head and blocks pain signals, usually relieving a migraine within two hours.

It comes as tablets for most people, a nasal spray for those who get nauseous, and a self-injection for the fastest relief or for cluster headaches.

FDA-approved uses

Acute migraine with or without aura
Acute cluster headache (injection)

Our doctors prescribe for approved uses. Any other use is a decision made only by your doctor, for you, after evaluation.

How it is taken

Taken at the first sign of migraine; a second dose may be taken after two hours if needed, within the daily maximum. It is not for prevention.

What to expect

Relief in 30 minutes to two hours. Tingling, flushing, tightness in the chest or throat, and drowsiness are common and usually brief.

Who should not take it

Coronary artery disease, prior stroke or uncontrolled high blood pressure
Hemiplegic or basilar migraine
Use within 24 hours of another triptan or ergot
Use with MAO inhibitors

Questions we hear

How many days a month can I use it?

Generally fewer than 10 to avoid medication-overuse headache; frequent migraines need a preventive plan.

Tablet or spray?

Spray works faster and bypasses nausea; tablets are simplest.

Is it safe in pregnancy?

Discuss with your doctor; data are reassuring but individual.
