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.
