Sumatriptan is a medication commonly used to treat migraine headaches. It belongs to a class of drugs known as triptans, which work by narrowing blood vessels in the brain and reducing inflammation. This helps alleviate the symptoms of a migraine, such as pain, nausea, and sensitivity to light and sound. Typically taken as a tablet, nasal spray, or injection, sumatriptan is most effective when taken at the first sign of a migraine. While it can provide relief for many, it may not be suitable for everyone, and potential side effects include dizziness, drowsiness, and tingling sensations. Always consult a healthcare professional before use.
