ve 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 after sumatriptan nasal solution, 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. |
