Rizatriptan is a medication commonly prescribed to treat acute migraines in adults. It belongs to a class of drugs known as triptans, which work by constricting dilated blood vessels in the brain and alleviating migraine symptoms. Understanding the correct dosage of rizatriptan is essential for its effectiveness and to minimize potential side effects.
