Table of contents:

Sumatriptan is an antimigraine medication indicated to treat migraines. Sumatriptan belongs to a class of drugs known as triptans, which are selective serotonin receptor agonists (5-HT agonists) that are used to treat migraines. Triptans work by constricting blood vessels in the brain and reducing inflammation, which can help alleviate migraine symptoms.

Sumatriptan is typically used to help alleviate the pain associated with migraines as well as other symptoms such as nausea, vomiting, and sensitivity to light/sound. Prompt treatment with Sumatriptan can often help patients return to their normal routine and may reduce their need for additional pain medications.

Uses and Dosage

Sumatriptan comes in the form of a tablet to take orally with or without a meal or as directed by your doctor. This should be taken at the first signs of migraine. Swallow the whole tablet and drink a glass of water after that. Cutting, chewing, or crushing this drug is not recommended.

The recommended single dose of Sumatriptan for treating a migraine headache is typically between 25 mg to 100 mg to be taken by mouth. After 2 hours, you may repeat the dose if you experienced some relief from the first dose. The dose should not exceed a total of 200 mg in a 24-hour period.
