Sumatriptan is a medication used to treat migraines and cluster headaches. It works by narrowing the blood vessels in the brain, which reduces the symptoms associated with these types of headaches, such as throbbing pain, nausea, and sensitivity to light and sound.
It is available as a tablet, injection, or nasal spray and is taken as soon as possible after the onset of symptoms for best results. It is important to note that Sumatriptan is not a preventative medication and should not be taken on a regular basis.
As with all medications, there may be some side effects, such as dizziness, nausea, and drowsiness, but these are usually mild and temporary. If you experience any severe side effects or have concerns about taking Sumatriptan, talk to your doctor or pharmacist.

Each Sumatriptan Tablet contains a single dose of sumatriptan, which belongs to a group of medicines called triptans (also known as 5-HT1 receptor agonists).

• Short-lived/temporary muscle spasms of the jaw affecting jaw movement.
