What It's For & How To Take
Rizatriptan is used to treat the immediate pain of a migraine headache. This medication works by causing your blood vessels in your brain to narrow and decrease swelling. Rizatriptan also decreases the natural chemicals in your body that cause symptoms such as light and sound sensitivity as well as nausea and vomiting.
This medication may help stop a migraine from forming, decrease the need for other pain medications, and help someone get back to their normal activities quicker. Rizatriptan does not prevent future migraines; it only works for the migraine you are currently treating.
Rizatriptan is available in a tablet that you swallow or a tablet that melts in your mouth. When using the tablet that melts in your mouth, open the pouch just before taking the medication. Place the tablet on your tongue and let it dissolve with your saliva. No water is necessary.
Rizatriptan works best when it is taken at the first sign of a migraine. If you are familiar with how your migraine starts, you may take this medication when you first notice it. You do not need to wait for the pain to begin. This medication is not to be taken on a regular basis; it is only taken when needed to treat a migraine headache.
If you do not have any relief of your migraine after you take your first dose of rizatriptan, do not take a second dose until you talk with your doctor. If you experience some relief, but the pain is still there, you may take another dose after 2 hours, unless your doctor told you not to. Your doctor will tell you how many tablets you may take in 24 hours.
If this medication is used too often, your body may develop a tolerance to it, and it may not work as well. If you need to treat more than 4 migraines each month, talk to you doctor about it.
Talk with your doctor to make sure your headaches are caused by a migraine. Rizatriptan should not be used to treat headaches that are not migraine.
