As with any medicine, side effects are possible; some of the more common side effects of this drug include dizziness, nausea, and fatigue.

What Is Oxcarbazepine?

Oxcarbazepine (Trileptal®) is a prescription medication used to treat a specific type of seizure in people with epilepsy. Seizures are divided into two major categories -- partial seizures (also known as focal seizures) and generalized seizures. Partial seizures occur in just one part of the brain. Generalized seizures affect both sides of the brain. Oxcarbazepine is approved to control partial seizures in people with epilepsy.
