Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. Using too much rizatriptan may increase the chance of side effects.
Do not use this medicine for a headache that is not a migraine headache. Talk to your doctor about what to do for regular headaches.
To relieve your migraine as soon as possible, use rizatriptan as soon as the headache pain begins. Even if you get warning signals of a coming migraine (an aura), you should wait until the headache pain starts before using rizatriptan.
Lying down in a quiet, dark room for a while after you use this medicine may help relieve your migraine.
Ask your doctor ahead of time about any other medicine you may take if rizatriptan does not work. After you take the other medicine, check with your doctor as soon as possible. Headaches that are not relieved by rizatriptan are sometimes caused by conditions that need other treatment.
If you feel much better after a dose of rizatriptan, but your headache comes back or gets worse after a while, adults may use one additional dose of rizatriptan 2 hours after the first dose. Do not use more than 2 doses in any 24-hour period. Do not use this medicine for more than 10 days in any 30-day period, unless your doctor tells you to.
Swallow the tablet whole with a glass of water. Do not crush, break, or chew it.
Keep the orally disintegrating tablet in the blister pack inside the outer foil pouch until you are ready to take the medicine. Make sure your hands are dry and peel open the blister to remove the tablet. Place the tablet on your tongue and let it dissolve. You do not need to drink water to swallow the dissolved tablet.
