Proper Use

Do not use this medicine for a headache that is different from your usual migraines. Instead, check with your doctor.

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. Using sumatriptan during the aura probably will not prevent the headache from occurring. However, even if you do not use sumatriptan until your migraine has been present for several hours, the medicine will still work.

Lying down in a quiet, dark room for a while after you use this medicine may help relieve your migraine.

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.

You may take the tablet with or without food. Swallow the tablet whole with water or other liquids. Do not break, crush, or chew it.

This medicine comes with a patient information leaflet. Read and follow the instructions carefully. Ask your doctor if you have any questions.

Dosing

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.

  • For oral dosage form (tablets):
    • For migraine headaches:
      • Adults—25, 50, or 100 milligrams (mg) as a single dose. If you get some relief, or if the migraine comes back after being relieved, another dose may be taken 2 hours after the last dose. Do not take more than 200 mg in any 24-hour period.
      • Children—Use and dose must be determined by your doctor.

Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Description

Sumatriptan is used to treat acute migraine attacks in adults. It does not prevent migraine attacks nor treat certain types of migraine headaches (e.g., hemiplegic or basilar type).

Many people find that their headaches go away completely after they take sumatriptan. 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. Sumatriptan often relieves other symptoms that occur together with a migraine headache, such as nausea, vomiting, sensitivity to light, and sensitivity to sound.

Sumatriptan is not an ordinary pain reliever. It will not relieve any kind of pain other than migraine headaches. This medicine is usually used for people whose headaches are not relieved by acetaminophen, aspirin, or other pain relievers.

Sumatriptan has caused 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.

This medicine is available only with your doctor’s prescription.
