All 3 medicines, Tegretol (carbamazepin), Keppra (levetiracetam) and Dilantin (fenitoin) are used for treating epilepsy. Keppra is usually used as an additional medicine for treating epilepsies that are resistant to therapy.
You didn’t state how long you have been experiencing epilepsy and how often you were getting seizures despite the therapy but, according to the therapy, it is likely that you are experiencing resistant epilepsy.
Resistant epilepsies requires regular monitoring by a specialist – neurologist.
