Rizatriptan is used to treat the symptoms of migraine headaches (severe, throbbing headaches that sometimes are accompanied by nausea and sensitivity to sound and light). Rizatriptan is in a class of medications called selective serotonin receptor agonists. It works by narrowing blood vessels in the brain, stopping pain signals from being sent to the brain, and blocking the release of certain natural substances that cause pain, nausea, and other symptoms of migraine. Rizatriptan does not prevent migraine attacks or reduce the number of headaches you have.
Rizatriptan comes as a tablet and an orally disintegrating tablet to take by mouth. It is usually taken at the first sign of a migraine headache. If your symptoms improve after you take rizatriptan but return after 2 hours or longer, you may take a second tablet. However, if your symptoms do not improve after you take rizatriptan, do not take a second tablet before calling your doctor. Your doctor will tell you the maximum number of tablets you may take in a 24-hour period. Follow the directions on the package or prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take rizatriptan exactly as directed. Do not take more or less of it or take it more often than directed by the package label or prescribed by your doctor.
You may take your first dose of rizatriptan in a doctor's office or other medical facility where you can be monitored for serious reactions.

No water is needed to swallow disintegrating tablets. Do not open the foil packaging or remove the orally disintegrating tablet until just before your are ready to take it.
Call your doctor if your headaches do not get better or occur more frequently after taking rizatriptan.
If you take rizatriptan more often or for longer than the recommended period of time, your headaches may get worse or may occur more frequently. You should not take rizatriptan or any other headache medication for more than 10 days per month. Call your doctor if you need to take rizatriptan to treat more than four headaches in a 1-month period.
