What is Almotriptan?

Almotriptan is a headache medicine. It is believed to work by narrowing the 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 common tension headaches or any headache that seems to be different from your usual migraine headaches. Use this medication only if your condition has been confirmed by a doctor as migraine headaches.

Almotriptan may also be used for purposes other than those listed in this medication guide.

Almotriptan Dosage

How should I take Almotriptan?

Take this medication exactly as it was prescribed for you. Never take the medication in larger amounts, or take it for longer than recommended by your doctor. Overuse of migraine headache medicine can actually make your headaches worse. Follow the instructions on your prescription label.

Take almotriptan as soon as you notice headache symptoms, or after an attack has already begun.

Your doctor may want to give your first dose of this medicine in a hospital or clinic setting to see if you have any serious side effects.

Take one almotriptan tablet whole with a full glass of water.

After taking a tablet: If your headache does not completely go away, or goes away and comes back, take a second tablet two (2) hours after the first. Do not take more than two (2) almotriptan tablets in 24 hours. If your symptoms have not improved, contact your doctor before taking any more tablets.

Contact your doctor if you have more than four headaches in one month (30 days).

If you use almotriptan long-term, your doctor may want to check your heart function periodically using an electrocardiograph or ECG (sometimes called an EKG), a machine that measures electrical activity of the heart. This will help your doctor determine if it is still safe for you to use this medication. Do not miss any scheduled visits to your doctor.

Store almotriptan at room temperature away from moisture, heat, and light.

What happens if I overdose on Almotriptan?
