Oxtellar XR is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to control partial-onset seizures in people six years of age and older. Oxtellar XR may be prescribed as monotherapy (a stand-alone drug) or as an adjunctive medication with other antiepileptic drugs. Oxtellar XR is also referred to by its drug name, oxcarbazepine. Oxcarbazepine is also sold under the brand name Trileptal.

Oxtellar XR is an anticonvulsant, or in other words, a drug used to prevents seizures. Oxtellar XR is derived from carbamazepine and is metabolized into eslicarbazepine in the body. It is believed to work in cases of epilepsy by inhibiting nerve signals in the brain.
