WHAT TOPIRAMATE SANDOZ IS USED FOR
Topiramate Sandoz is used to treat various types of epilepsy in adults and children over 2 years of age, and to prevent migraines in adults.
Topiramate Sandoz contains the active ingredient topiramate.
Topiramate belongs to a group of medicines called anti-convulsants. It prevents seizures and migraines by acting on the nerves and chemicals in the brain.
Your doctor may prescribe Topiramate Sandoz on its own, or in addition to another medicine for controlling your seizures or migraines.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.

How much to take
The doses shown below are the usual recommended doses. However, your doctor may tell you to take higher or lower doses. Your doctor will start with a low dose and slowly increase the dose to the lowest amount needed to control your epilepsy.
At the start of treatment Topiramate Sandoz may be taken once a day, preferably at night. After the dose is increased, it is taken twice a day.
You should continue taking Topiramate Sandoz until your doctor tells you to stop. Before stopping, it is recommended that the dose be reduced gradually.
