Sumatriptan is a type of medication known as a serotonin agonist. It is prescribed to treat migraines headache symptoms with or without aura and cluster headaches. Symptoms of migraine headaches may include severe, throbbing pain accompanied by sensitivity to light and sound and sometimes nausea. It is available as an oral tablet both brand and generic names. It often comes as an injectable solution, nasal spray or nasal powder.
Migraine is a recurring type of headache that causes severe pain often on one side of the head. It’s a neurological condition with multiple symptoms such as nausea, difficulty speaking, vomiting, sensitivity to light and sound and numbness or tingling. Headache is only one symptom of migraine which can range in severity and may last anywhere from a few hours to several days. The exact cause of migraine is unknown but it appears that migraine headaches may be caused by changes in the body’s level of a chemical known as serotonin. This chemical plays an important role in the body. When the level of serotonin is high, the blood vessel shrinks and when it falls the blood vessels swell. The swelling of the blood vessel is what causes the pain.
Sumatriptan is an inexpensive drug approved by the Food and Drug Administration since 1991 to treat acute migraine headaches in adults. It acts on the serotonin receptors in the blood vessels in the brain. This blocks the pain pathway and prevents the blood vessels from narrowing thus relieving migraine symptoms.
How to Use It
Sumatriptan is available in 50mg and 100mg tablets for you to take by mouth. The typical recommended dose is 25mg to 100mg and the maximum recommended dose is 200mg within 24 hours.
