- What Sumatriptan Tablets are and what they are used for
Each Sumatriptan Tablet contains a single dose of sumatriptan, which belongs to a group of medicines called triptans (also known as 5-HT1 receptor agonists).
Sumatriptan Tablets are used to treat migraine headache.
Migraine symptoms may be caused by the temporary widening of blood vessels in the head. Sumatriptan Tablets are believed to reduce the widening of these blood vessels. This in turn helps to take away the headache and relieve other symptoms of a migraine attack, such as feeling or being sick (nausea or vomiting) and sensitivity to light and sound.
