Rizact is used for treating migraine headaches with or without aura (eg, flashing lights, wavy lines, dark spots). It should not be used to prevent migraines or to treat cluster headaches. It works by narrowing dilated blood vessels in the brain, relieving migraine headaches.
Use rizatriptan as directed by your doctor. Take rizatriptan by mouth with or without food. Take rizatriptan with plenty of fluid.
It is best to take a dose of rizatriptan as soon as you notice symptoms of a migraine attack. If your symptoms do not improve after the first dose, do not take a second dose for the same attack. Contact your doctor.
Take exactly as prescribed by your doctor. If your symptoms do not improve after the first dose, do not take a second dose for the same attack. Contact your doctor.
Do not take more than the amount prescribed by your doctor in a 24-hour period. If you miss a dose of rizatriptan and you still have a headache, follow your doctor’s dosing instructions. Contact your doctor right away if you are unsure of what to do if you miss a dose. Do not take rizatriptan more often than prescribed. Do not take 2 doses at once.
Store at 15-30°C. Keep out of the reach of children and away from pets.

you are allergic to any ingredient in rizatriptan; you have a history of ischemic heart disease (eg, angina, a heart attack), coronary artery disease (CAD), other moderate to severe heart problems, brain blood vessel disease (eg, a stroke, a transient ischemic attack), or other blood vessel disease (eg, Raynaud syndrome, ischemic bowel disease); you have uncontrolled high blood pressure; you have certain types of migraine headache (hemiplegic, basilar); you are taking or have taken a monoamine oxidase inhibitor (MAOI) (eg, phenelzine) within the past 14 days; you have used certain other migraine medicines within the past 24 hours.
