Naratriptan is a headache medicine that narrows blood vessels around the brain. Naratriptan also reduces substances in the body that can trigger headache pain, sensitivity to light and sound, and other migraine symptoms.
Naratriptan is used to treat migraine headaches. Naratriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Naratriptan should not be used to treat a common tension headache, a headache that causes loss of movement on one side of your body, or any headache that seems to be different from your usual migraine headaches. Use this medicine only if your condition has been confirmed by a doctor as migraine headaches.
Naratriptan may also be used for purposes not listed in this medication guide.

If your symptoms have not improved after taking 2 tablets in 24 hours, contact your doctor before taking any more tablets.
Tell your doctor if you have more than four headaches in one month (30 days).
