Naratriptan is a prescription medicine used to treat migraine headaches in adults.  Naratriptan belongs to a group of drugs called 5-HT agonists or "triptans".  It is believed to work by causing dilated blood vessels in the brain to narrow.

Naratriptan comes in tablet form and is taken by mouth as soon as a migraine starts.

Common side effects of naratriptan include dizziness, feeling hot or cold, and light sensitivity.
