How does this medication work? What will it do for me?
Rizatriptan belongs to a class of medications known as 5-hydroxytryptamine agonists (also called triptans). It is used to treat migraine headaches with or without aura (warning signs that occur prior to the onset of a migraine headache). The pain of migraine headaches is thought to be caused by dilated blood vessels inside the head. Rizatriptan relieves migraine headaches by constricting these blood vessels.
Rizatriptan is most effective if taken at the first sign of a migraine headache. It is not recommended for other types of headache or for headache prevention. Relief from the pain associated with migraine may occur as quickly as within 30 minutes, with maximum pain relief occurring about 2 hours after taking the medication.

How should I use this medication?
The recommended adult starting dose of rizatriptan is 5 mg. In some cases, a starting dose of 10 mg may be used. The dose should be taken at the first sign of migraine headache pain. If the migraine headache comes back after being relieved, another dose (5 mg to 10 mg) may be taken no sooner than 2 hours after the first dose was taken.
The maximum recommended single dose is 10 mg. No more than 20 mg of rizatriptan should be taken in any 24-hour period. If your headache pain is different from your usual migraines, call your doctor and do not take rizatriptan. Rizatriptan is not to be used for headache prevention.
It is important to take this medication exactly as prescribed by your doctor.
For the wafer form of rizatriptan, it is not necessary to take the wafer with water. The wafer is packaged in a blister with an outer aluminum pouch.
