Thank you for posting your query.

Epilepsy is a disease, requiring long-term medications. Seizures may recur, even while on medications. As your doctor said, the chances are higher with fever, lack of sleep, etc.

After changing the dose, it may take 5-7 days for the drug effect to optimize.

Please get back if you require any additional information.

Best wishes,
