What is the dosage and how should it be used?

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.

For nasal dosage form (nasal solution):

For migraine headaches:
Adults - 5 milligrams (mg) or 10 mg (1 or 2 sprays into each nostril), or 20 mg (1 spray into one nostril). If the pain is not relieved, another spray (5 mg, 10 mg, or 20 mg) should not be used for the same migraine attack. Another spray (5 mg, 10 mg, or 20 mg) may be used for a migraine that occurs at a later time as long as it has been at least two hours since the last spray. Do not use more than 40 mg in a twenty-four-hour period (one day).

Children - use and dose must be determined by your doctor.

For oral dosage form (tablets):

For migraine headaches:
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.

Children - use and dose must be determined by your doctor.

For parenteral dosage form (injection):

For migraine or cluster headaches:
Adults - one 6 mg injection. One more 6-mg dose may be injected, if necessary, if the migraine comes back after initial relief. However, the second injection should not be given any sooner than one hour after the first one. Do not use more than two 6 mg injections in a 24-hour period (one day). However, some people may be directed to use no more than two 6 mg doses in a 48-hour period (two days).
