What is Sumatriptan?
Sumatriptan is the generic version of the brand-name medicine Imigran. Both of these medications are used to treat migraines. Migraine headaches are thought to be caused by the dilation of blood vessels. Sumatriptan constricts these blood vessels which ultimately relieves the migraine symptoms.
How does Sumatriptan work?
The active ingredient in Sumatriptan is sumatriptan, which belongs to a group of medicines called serotonin receptor (5-HT1) agonists. Sumatriptan works by stimulating serotonin, which then reduces inflammation and constricts blood vessels. This alleviates the symptoms of a migraine.
How do you take Sumatriptan?
Always take this medication as it has been prescribed to you by your doctor or pharmacist.
Take one Sumatriptan tablet as soon as you feel a migraine starting. Do not take Sumatriptan tablets preventatively; only take Sumatriptan once migraine symptoms begin.
The standard dose for adults aged 18 - 65 is one 50 mg tablet for a migraine attack. Some patients are prescribed 100 mg. Take this medicine as directed.
