Common Name: rizatriptan
How does Maxalt work?Rizatriptan is used to treat migraine headaches. The pain of migraine headaches is thought to be caused by dilated blood vessels inside the head. Rizatriptan belongs to a class of drugs known as 5-hydroxytryptamine agonists that relieve migraine headaches by constricting these blood vessels. Rizatriptan is most effective if taken at the first sign of a migraine headache. The tablets are not effective for other types of headache. Relief from the pain associated with migraine occurs quickly, with maximum pain relief occurring about two hours after taking the medication. Your doctor may choose to use this medication for other conditions not listed here. If you're unsure why you are taking this medication, contact your doctor.
How should I use Maxalt?The recommended initial adult dose of rizatriptan is 5 mg. In some cases, an initial 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 two 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, do not take rizatriptan; call your doctor. Rizatriptan is not to be used for headache prevention. For the wafer form of rizatriptan (Maxalt-RPD®), it is not necessary to take the wafer with water. The wafer is packaged in a blister with an outer aluminum pouch. Do not remove the wafer from the package until you are ready to use it. When you are ready, peel open the blister pack with dry hands and place the wafer on your tongue. Allow the wafer to dissolve on your tongue, and swallow. Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without talking to your doctor. Always take rizatriptan exactly as prescribed by your doctor.
