What Sumatriptan is and what it is used for

Sumatriptan is used in acute treatment of migraine attacks with or without aura. The symptoms of
migraine may be caused by a temporary swelling of blood vessels in your head. This type of medicine
works by reducing this swelling. These are one of a group of medicines called 5HT1 receptor agonists
that are used to treat migraine.
Sumatriptan cannot prevent a migraine attack.
