Sumatriptan is a medication commonly used for the treatment of migraines. It belongs to a class of drugs called triptans. When you take sumatriptan, it narrows the blood vessels in the brain and reduces inflammation, which helps relieve the symptoms of a migraine attack. Sumatriptan can help alleviate migraine symptoms such as headache, sensitivity to light and sound, and nausea. Some individuals may experience relief from their migraine symptoms after taking sumatriptan, while others may not find it as effective. It is always best to consult with your doctor or pharmacist to determine the most suitable treatment option for your specific situation.
