What TOPAMAX is used for
The name of your medicine is TOPAMAX. It contains the active ingredient topiramate.
TOPAMAX belongs to a group of medicines known as antiepileptics. TOPAMAX is used for
the treatment of various types of seizures in adults and children, aged 2 years and
over. It can also be used for the prevention of migraines in adults. TOPAMAX is not
used to treat severe migraines that come on suddenly (acute).
It prevents seizures and migraines by acting on the nerves and chemicals in the brain.
Your doctor may prescribe TOPAMAX on its own, or in addition to another medicine for
controlling your seizures or migraines.
Your doctor may have prescribed TOPAMAX for another reason. Ask your doctor if you
have any questions about why this medicine has been prescribed for you.
