For 70% of patients with epilepsy, drugs can control seizures. However, they can't cure epilepsy, and most people will need to continue taking medications.An accurate diagnosis of the type of epilepsy (not just the type of seizure, because most seizure types occur in different types of epilepsy) a person has is very important in choosing the best treatment. The type of medication prescribed will also depend on several factors specific to each patient, such as which side effects can be tolerated, other illnesses he or she may have, and which delivery method is acceptable.
