How to Use
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. Afte
r 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 s
umatriptan does not relieve one migraine, it may still relieve the next one.

injections are used to treat vascular headaches such as migraine and cluster headaches. Imitrex ( Sumatriptan ) will not prevent migraines or cluster headaches or reduce the number of attacks. It will
