Many people find that their headaches go away completely after they take rizatriptan.
Other people find that their headaches are much less painful, and that they are able to go back to their normal activities even though their headaches are not completely gone. Rizatriptan is not an ordinary pain reliever. It should not be used to relieve any kind of pain other than migraine headaches. Rizatriptan may cause serious side effects in some people, especially people who have heart or blood vessel disease. Be sure that you discuss with your doctor the risks of using this medicine as well as the good that it can do.
