## What is rizatriptan?

Rizatriptan is a headache medicine that narrows the blood vessels around the brain. Rizatriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.

Rizatriptan is used to treat migraine headaches. Rizatriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.

Rizatriptan should not be used to treat a common tension headache, or a headache that causes loss of movement on one side of your body. Use rizatriptan only if your condition has been confirmed by a doctor as migraine headaches.

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

## Warnings

You should not use this medicine 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 rizatriptan within 24 hours before or after using another migraine headache medicine.

Do not use this medicine if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

## How should I use rizatriptan?

Take rizatriptan as soon as you notice headache symptoms. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

You may receive your first dose in a hospital or clinic setting to quickly treat any serious side effects.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Take the regular tablet whole with a full glass of water.

Remove an orally disintegrating tablet from the package only when you are ready to take the medicine. Place the tablet in your mouth and allow it to dissolve, without chewing. Swallow several times as the tablet dissolves.

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

After taking a tablet (for children ages 6 to 17): If your headache does not completely go away, or goes away and comes back, contact your doctor before taking any more tablets.

Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks.

Call your doctor if your symptoms do not improve, or if you have more than 4 headaches in one month (30 days).

Rizatriptan can raise blood pressure to dangerous levels. Your blood pressure may need to be checked often while you are using rizatriptan. If you use rizatriptan long-term, your heart function may need to be checked using an electrocardiograph or ECG (sometimes called an EKG).

Store at room temperature away from moisture and heat.
