The active ingredient in Maxalt is rizatriptan benzoate.
How does Maxalt work?
Maxalt works by binding with 5-HT1B/1D receptors on blood vessels in the brain. It narrows the blood vessels (constriction) in the brainstem. It also reduces inflammatory substances in the body that can trigger head pain, nausea, sensitivity to light and sound, and other migraine symptoms. Maxalt works best if it is taken as soon as migraine symptoms appear.

If there is no response to the first migraine attack treated with the Maxalt, a physician should reconsider the migraine diagnosis prior to using the medication in any subsequent attacks.
A cardiovascular evaluation should be performed on patients who have never taken a triptan medication but who have multiple cardiovascular risk factors (e.g., increased age, diabetes, hypertension, smoking, obesity, strong family history of CAD) before starting Maxalt. For those with a cardiac history, the first dose of Maxalt should be administered in a medically supervised setting, and an electrocardiogram (ECG) should be performed immediately following the dose.
Maxalt tablets are taken by mouth with water or other liquids. Adults take a 5 mg or 10 mg single dose; repeated doses can be taken separated by least two hours. The maximum adult dose in a 24-hour period is 30 mg. Children from age 6 to 17 weighing less than 88 pounds take a 5 mg single dose; those 88 pounds or more can take 10 mg. The maximum dose for children is a single dose.
A physician will determine the appropriate dose for each patient. If only partial migraine relief is attained or symptoms return quickly, a second dose may be taken 2 hours after the first (except for children).
Keep track of when you have migraine attacks and when you take Maxalt so you can monitor its effectiveness, and communicate with your doctor about how the medication is working for you.
