Sumatriptan is a prescription medication that is used to treat migraines which are commonly described as a moderate to severe throbbing pain on one side of the head. As well as relieving headache pain, it has proven to be effective when tackling other symptoms of migraines which can include nausea, vomiting and sensitivity to sound and light. Some migraines also come with an aura which sufferers describe as a being bright lights, blind spots or zigzags in their vision.
Sumatriptan belongs to a class of drugs known as triptans, also known as 5-HT1 receptor agonists. The triptans bind to receptors and reduce the swelling of blood vessels in the brain which is thought to be the trigger for a migraine.
