In the U.S.-
Sumatriptan (soo-ma-TRIP-tan) is used to treat severe migraine headaches. 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 injection is also used to treat cluster headaches.
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.
Sumatriptan is available only with your doctor's prescription, in the following dosage forms:
Before Using This Medicine
In deciding to use a medicine, the risks of using the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For sumatriptan, the following should be considered:
Allergies- Tell your doctor if you have ever had any unusual or allergic reaction to sumatriptan. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Pregnancy- Sumatriptan has not been studied in pregnant women. However, in some animal studies, sumatriptan caused harmful effects to the fetus. These unwanted effects usually occurred when sumatriptan was given in amounts that were large enough to cause harmful effects in the mother.
Breast-feeding- Sumatriptan passes into human breast milk. Breast-feeding mothers should discuss the risks and benefits of this medicine with their doctors.
Children- Studies on this medicine have been done only in patients 18 years of age or older, and there is no specific information comparing use of sumatriptan in children with use in other age groups.
Older adults- This medicine has been tested in a limited number of patients between 60 and 65 years of age. It did not cause different side effects or problems in these patients than it did in younger adults. However, there is no specific information comparing use of sumatriptan in patients older than 65 years of age with use in younger adults.
Other medicines- Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine, especially other prescription medicine for migraine headaches, or if you smoke tobacco.
When you are taking sumatriptan, it is especially important that your health care professional know if you are taking the following:
Other medical problems- The presence of other medical problems may affect the use of sumatriptan. Make sure you tell your doctor if you have any other medical problems, especially:
Proper Use of This Medicine
Do not use sumatriptan for a headache that is different from your usual migraines . Instead, check with your doctor.
To relieve your migraine as soon as possible, use sumatriptan 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 are not much better in 1 or 2 hours after an injection of sumatriptan, or in 2 to 4 hours after a tablet is taken, do not use any more of this medicine for the same migraine . A migraine that is not relieved by the first dose of sumatriptan probably will not be relieved by a second dose, either. Ask your doctor ahead of time about other medicine to be taken if sumatriptan does not work. After taking 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. However, even if sumatriptan does not relieve one migraine, it may still relieve the next one.
If you feel much better after a dose of sumatriptan, but your headache comes back or gets worse after a while, you may use more sumatriptan. 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.
Your doctor may direct you to take another medicine to help prevent headaches. It is important that you follow your doctor's directions, even if your headaches continue to occur . Headache-preventing medicines may take several weeks to start working. Even after they do start working, your headaches may not go away completely. However, your headaches should occur less often, and they should be less severe and easier to relieve. This can reduce the amount of sumatriptan or pain relievers that you need. If you do not notice any improvement after several weeks of headache-preventing treatment, check with your doctor.

The dose of sumatriptan 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 sumatriptan. If your dose is different, do not change it unless your doctor tells you to do so.

Precautions While Using This Medicine
Check with your doctor if you have used sumatriptan for three headaches, and have not had good relief. Also, check with your doctor if your migraine headaches are worse, or if they are occurring more often, than before you started using sumatriptan.
Drinking alcoholic beverages can make headaches worse or cause new headaches to occur. People who suffer from severe headaches should probably avoid alcoholic beverages, especially during a headache.
Some people feel drowsy or dizzy during or after a migraine, or after taking sumatriptan to relieve a migraine. As long as you are feeling drowsy or dizzy, do not drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert .
Side Effects of This Medicine
Along with its needed effects, a medicine may cause some unwanted effects. Most side effects of sumatriptan are milder and occur less often with the tablets than with the injection. Although not all of these side effects may occur, if they do occur they may need medical attention.
Stop using this medicine and check with your doctor immediately if any of the following side effects occur :
Check with your doctor right away if any of the following side effects continue for more than 1 hour . Even if they go away in less than 1 hour, check with your doctor before using any more sumatriptan if any of the following side effects occur :
Also check with your doctor as soon as possible if any of the following side effects occur:
Other side effects may occur that usually do not need medical attention. Some of the following effects, such as nausea, vomiting, drowsiness, dizziness, and general feeling of illness or tiredness, often occur during or after a migraine, even when sumatriptan has not been used. Most of the side effects caused by sumatriptan go away within a short time (less than 1 hour after an injection or 2 hours after a tablet). However, check with your doctor if any of the following side effects continue or are bothersome:
Other side effects not listed above may also occur in some patients. If you notice any other effects, check with your doctor.
