Rizatriptan tablets are a prescription-only medicine designed to treat migraine headaches in adults. Migraines can cause severe pain, nausea, and sensitivity to light or sound, and these tablets help relieve symptoms quickly when taken at the first sign of an attack.
Rizatriptan tablets are used to treat migraines. They contain the active ingredient rizatriptan, which is a type of medicine called a serotonin agonist that blocks the release of serotonin in the brain. Serotonin is a substance that occurs naturally in the brain and is responsible for causing migraines. Migraine is often caused by dilatation of the blood vessels in the head. Rizatriptan works by blocking the release of serotonin, thus causing the blood vessels in the head to narrow, thereby relieving the pain of migraine. Rizatriptan tablets can also help to reduce the duration of a migraine attack.
