How does this medication work? What will it do for me?
Sumatriptan belongs to a class of medications known as 5-hydroxytryptamine agonists (also called "triptans"). It is used to treat migraine headaches with or without aura (warning signs that occur prior to the onset of a migraine). The pain of migraine headaches is thought to be caused by dilated blood vessels inside the head. Sumatriptan relieves migraine headaches by constricting these blood vessels.
Sumatriptan is not recommended for other types of headache or for headache prevention.
In most people, sumatriptan eliminates or reduces the symptoms of migraine, including headache, nausea, vomiting, and sensitivity to light and sound. Significant relief of migraine pain is usually experienced by about 10 to 15 minutes after using the injection, 15 minutes after using the nasal spray, and about 30 minutes after taking the oral tablets.

How should I use this medication?
The recommended adult dose of the tablets ranges from 25 mg to 100 mg. The most common dose is 50 mg.
If the headache returns, or if there is partial but not total relief, the dose may be repeated after 2 hours. If a dose has not helped your headache at all, do not take a second dose without first consulting a doctor. No more than 200 mg should be taken during any 24-hour period.
Swallow the tablet whole with water. Do not crush, chew, or split the tablets. The DF tablets have been formulated to disintegrate and release medication into the stomach so that it is absorbed into the bloodstream.
It is important to take this medication exactly as prescribed by your doctor.
