Rizatriptan is a headache medicine. It is believed to work by narrowing 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. How Taken Rizact
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 rizatriptan 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 rizatriptan tablet whole with a full glass of water. To take rizatriptan orally disintegrating tablets:
- Keep the tablet in its blister pack until you are ready to take the medicine. Open the package and peel back the foil from the tablet blister. Do not push a tablet through the foil or you may damage the tablet.
- Using dry hands, remove the tablet and place it in your mouth. It will begin to dissolve right away.
- Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing.

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 30 mg of rizatriptan 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 rizatriptan 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. Warnings Precautions Rizact
