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 almotriptan only if your condition has been confirmed by a doctor as migraine headaches.

Almotriptan may also be used for purposes not listed in this medication guide.

You should not use almotriptan if you have uncontrolled high blood pressure, heart problems, a history of heart attack or stroke, or circulation problems that cause a lack of blood supply within the body.

Do not take almotriptan within 24 hours before or after using another migraine headache medicine.

Stop using almotriptan and get emergency medical help if you have: chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating, and a light-headed feeling.

Your doctor may want to give your first dose of almotriptan in a hospital or clinic setting to quickly treat any serious side effects that occur.

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Take almotriptan as soon as you notice migraine symptoms.

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

Call your doctor if your headache does not go away at all after taking the first almotriptan tablet.

Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse.

Contact your doctor if you have more than four headaches in one month (30 days). Tell your doctor if this medicine seems to stop working as well in treating your migraine attacks.

If you use almotriptan long-term, your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG). This will help your doctor determine if it is still safe for you to take almotriptan.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
