What is sumatriptan injection?

Sumatriptan is a headache medicine. It is believed to work by narrowing the blood vessels around the brain. Sumatriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.

Sumatriptan injection is used to treat migraine headaches and cluster headaches.
