Do not use this medicine for a headache that is different from your usual migraines. Talk to your doctor about what to do for regular headaches.
To relieve your migraine as soon as possible, use this medicine 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 sumatriptan.
Ask your doctor ahead of time about any other medicine you might take if sumatriptan does not work. After you use the other medicine, check with your doctor as soon as possible. Headaches that are not relieved by sumatriptan are sometimes caused by conditions that need other treatment.
If you feel much better after a dose of sumatriptan, but your headache comes back or gets worse after a while, wait at least 2 hours before taking another dose. However, use this medicine only as directed by your doctor. Do not use more of it, and do not use it more often, than directed. Using too much sumatriptan may increase the chance of side effects. Do not take more than 200 mg in 24 hours.
Swallow the tablet whole with water or other liquids. Do not crush, break, or chew it.
You may take the tablet with or without food.

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
