What is Sumatriptan Succinate: Uses, Warnings & Interactions

Updated May 14, 2025  •  Published Dec 30, 2020

Sumatriptan succinate is a generic prescription drug that quickly ends migraine headaches. It reverses some of the mechanisms that cause migraine headaches: nerve signals, dilation of the arteries in the head, and inflammation of the membranes surrounding and protecting the brain. Its onset of action is fast, but the speed of relief depends on how it’s taken. Oral tablets are the slowest to provide relief, and injections work much faster. Patients can give themselves injections using an auto-injector or syringe and needle.
