Sumatriptan Uses Sumatriptan is used for the treatment of acute migraine headaches. It alleviates the symptoms of migraines and prevents the attack from worsening.
How Sumatriptan works Migraine headaches are believed to result from the dilation (swelling) of blood vessels in the head. Sumatriptan works by constricting (narrowing) these blood vessels, stopping the transmission of pain signals to the brain, and blocking the release of chemicals that cause nausea and other migraine symptoms. This alleviates the migraine attack.
Common side effects of Sumatriptan include vomiting, nausea, a burning sensation, general discomfort, itching, urticaria, rash, inflammation of the veins, dry lips, skin peeling, and dry skin.
