What Is Nizatidine?

Almotriptan is a headache medicine that narrows blood vessels around the brain. Almotriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.
Almotriptan is used to treat migraine headaches in adults and in adolescents who are at least 12 years old. Almotriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Almotriptan 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.
