Do not drink alcohol. Dangerous side effects or increased seizures may occur.
Avoid becoming overheated or dehydrated in hot weather. Topiramate can increase body temperature and decrease sweating, leading to life-threatening dehydration (especially in children).
Avoid the use of a ketogenic or "ketosis" diet (high in fat, low in carbohydrates) while you are taking topiramate.
Topiramate may cause blurred vision or impair your thinking or reactions. Avoid driving or operating machinery until you know how  topiramate will affect you.
Also avoid activities that could be dangerous if you have an unexpected seizure, such as swimming or climbing in high places.
