The reference site for Sumatriptan

Sumatriptan is a medication used for the treatment of migraine and cluster headaches.

WHAT IS Sumatriptan?

Sumatriptan is an antimigraine medicine. Migraine headaches are believed to result from dilatation of the blood vessels in the head. Sumatriptan causes constriction of the blood vessels, thus relieving migraine headache.

This medicine is usually used for people whose headaches are not relieved by acetaminophen, aspirin, or other pain relievers.

Despite that sumatriptan is highly effective in relieving migraines, it unfortunately does not prevent or reduce the number of attacks.

FDA Information

Sumatriptan was approved by the FDA in 1993.

Sumatriptan was the first triptan available and, in the United States and most developed countries, is available only by medical prescription. In the United Kingdom, sumatriptan is available over the counter under the name of Imigran Recovery®. It is sold in packs of two 50mg tablets for approximately £7.99.

Larger pack sizes, the nasal spray, and the liquid preparation for injection are still only available by prescription.

Please visit the official site of the FDA for further information.

Why is this medication prescribed?

Sumatriptan is used to relieve migraines and its associated nausea and light sensitivity.

Migraine headaches are believed to result from dilatation of the blood vessels in the head. Sumatriptan causes constriction of the blood vessels, thus relieving migraine headache.

Despite that this medication is very effective in relieving migraines, it does not prevent or reduce the number of migraine attacks.

Sumatriptan is usually used for people whose headaches are not relieved by acetaminophen, aspirin, or other pain relievers.

Other uses for this medicine

This drug may also be used for certain other types of headaches.

However, it is important that you talk to your doctor before using this drug about the possible risks for your particular condition.

Dosage and using this medicine

Do not use sumatriptan for a headache that is different from your usual migraines. Instead, consult 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 will not probably 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. Nevertheless, 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, only use this medicine as directed by your doctor. Never use more of it, or increase the dosage, than that directed by your doctor. 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. Despite this, 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.

Adults – 25, 50 or 100 mg as a single dose. If you get some relief, or if the migraine comes back after being relieved, another dose may be taken two hours after the last dose. Do not take more than 200 mg in any 24-hour period. If you are taking the tablets after using an injection, you may take single doses of up to 100 mg a day with two hours between doses. Do not take more than 200 mg in a 24-hour period.
