Trileptal is the brand name for Oxcarbazepine, an anticonvulsant (antiepileptic) medication manufactured by Novartis Pharmaceuticals. It is FDA-approved to treat partial (focal) seizures in adults and children aged 4 to 16, either as a standalone treatment or alongside other seizure medications. Doctors also prescribe Trileptal off-label for bipolar disorder, trigeminal neuralgia, and neuropathic pain.
Trileptal works by blocking voltage-sensitive sodium channels in the brain, which reduces high-frequency repetitive neuronal firing that leads to seizures. It also inhibits the release of glutamate, an excitatory neurotransmitter. After you take it, Oxcarbazepine is rapidly converted in your body to its active metabolite called licarbazepine (also known as MHD), which is primarily responsible for the antiseizure effects.

Trileptal (Oxcarbazepine) scores a 70 out of 100 on our findability scale, meaning it has intermittent availability issues. There is no active FDA shortage as of early 2026, but periodic supply disruptions from specific generic manufacturers can make certain strengths or formulations temporarily unavailable at individual pharmacies. If your local pharmacy is out of stock, trying a different pharmacy or using Medfinder to search nearby locations can help you find it faster.
Trileptal is most commonly prescribed by neurologists and epileptologists who specialize in seizure disorders. It can also be prescribed by psychiatrists (for off-label bipolar disorder use), pediatric neurologists, pain management specialists, and primary care or family medicine doctors. Telehealth consultations are also available for Trileptal prescriptions.
No, Trileptal (Oxcarbazepine) is not a controlled substance. It does not have a DEA schedule and does not require special prescribing restrictions. However, it is a prescription-only medication, so you will need a valid prescription from a licensed healthcare provider to obtain it.
Serious but less common side effects include hyponatremia (low sodium levels), severe skin reactions such as Stevens-Johnson syndrome, suicidal thoughts, and blood disorders. Patients of Asian descent should be screened for the HLA-B*1502 allele before starting Trileptal due to the risk of severe skin reactions.
