Contents of the pack and other information
1. What Sumatriptan is and what it is used for
Each Sumatriptan film-coated tablet contains a single dose of sumatriptan, which belongs to a group of
medicines called triptans (also known as 5-HT1 receptor agonists).
Sumatriptan is used to treat migraine headache.
Migraine symptoms may be caused by the temporary widening of blood vessels in the head. Sumatriptan is
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.
