What Is Oxcarbazepine Extended-Release?

Oxcarbazepine extended-release (Oxtellar XR™) is a prescription medication approved to treat partial seizures in adults and children as young as six years old. Partial seizures are seizures that occur in one part of the brain. This medication is used in combination with other anti-seizure medicines.
Oxcarbazepine extended-release contains the same active ingredient as Trileptal® (oxcarbazepine), but in a long-acting form. Because it is long-acting, it needs to be taken only once a day.
