Both of these are Anti Epileptic (anti seizure ) drugs.Although anti-epileptic drugs can control seizures, they cannot cure epilepsy. This is why they need to be taken every day to help stop seizures from happening. It is important not to attempt to reduce or withdraw medication without specialist advice.A number of factors have to be considered, including whether there is a physical cause for your epilepsy and how long it took for your seizures to be controlled. If it is decided to come off medication, it is usual for this to be a very gradual process as abrupt withdrawal can, in itself, trigger a seizure. Some types of epilepsy, such as Juvenile Myoclonic Epilepsy, respond well to anti-epileptic drugs, but the majority of people with this type of epilepsy need to take medication for life. This is because there is a high instance of seizures recurring when drugs are stopped. </s>
