Sumatriptan, sold under the brand name Imitrex among others, is a medication used to treat migraine headaches and cluster headaches.[1] It is taken orally, intranasally, or by subcutaneous injection.[2] Therapeutic effects generally occur within three hours.[2]

Its primary effect as a serotonin 5-HT1B/5-HT1D receptor agonist[3] can create common side effects such as chest pressure, fatigue, vomiting, tingling, and vertigo. Serious side effects may include serotonin syndrome, heart attacks, strokes, and seizures. With excessive use, medication overuse headaches may occur.[2] It is unclear if use during pregnancy or breastfeeding is safe.[4] The mechanism of action is not entirely clear. It is in the triptan class of medications.[2]

Sumatriptan was patented in 1982 and approved for medical use in 1991.[5] It is on the World Health Organization's List of Essential Medicines.[6] It is available as a generic medication.[1] In 2022, it was the 95th most commonly prescribed medication in the United States, with more than 6 million prescriptions.[7][8] It is also available as the combination product sumatriptan/naproxen.
