Sumatriptan is a 5-HT1 receptor agonist used for the treatment of acute migraine and cluster headaches. It works by constricting blood vessels in the brain and reducing inflammation associated with migraines.

The medication is available in the form of tablets, injections, or nasal spray and should be taken as directed by a doctor, usually at the onset of migraine symptoms.

Patients should be aware of potential side effects, such as dizziness, nausea, or a sensation of pressure in the chest. It is important to inform the doctor of any unusual symptoms.

Common side effects include dizziness, nausea, fatigue, and tingling sensations. In rare cases, severe reactions such as high blood pressure or myocardial ischemia may occur. Patients should be informed of these risks before starting treatment.
