What Is Trileptal?
Trileptal, also known by its generic name oxcarbazepine, is a medication that is FDA-approved in the treatment of seizures. There is another brand of oxcarbazepine called Oxtellar XR, which is an extended-release medication as opposed to Trileptal’s immediate-release formulation. This article will focus on Trileptal. Also known as an anticonvulsant or antiepileptic drug, Trileptal helps to suppress excessive rapid firing of the nerves, preventing or treating seizures. Other than seizure control, Trileptal may be used off-label as a treatment for bipolar disorder.1, 2
Can Trileptal be Used to Treat Bipolar Disorder?
Trileptal can be used in the treatment of bipolar disorder, but this is an off-label indication. It is one of many possible medications used for bipolar disorder. This medication is typically used after the first-line options are exhausted or if there are complications that prevent someone from taking those medications. It has been suggested that Trileptal may be useful in controlling acute manic episodes in patients with bipolar disorder, although more data is needed to determine if it is effective for maintenance treatment.3
The difference between FDA-approved and off-label use is that a medication with FDA approval has gone through a formal process to determine that medication is safe and effective for that use. Off-label use is when a medication has not undergone the FDA approval process but may be used as a treatment for some conditions.1, 2
Which Is Better, Lamictal or Trileptal?
Both medications are effective for the reasons they are prescribed. Lamictal is approved as a treatment for seizures and bipolar disorder, unlike Trileptal, which is used off-label for bipolar disorder.4 When treating bipolar disorder, Lamictal can treat both mania and depression but tends to be more effective with depression symptoms. Trileptal is thought to be better suited for mania. 5, 6 The right medication for you depends on your condition as well as personal factors you can discuss with your doctor.
Is Trileptal Similar to Gabapentin?
Trileptal and gabapentin are similar in that they are both anticonvulsants used to treat seizures, but they differ in how gabapentin is used as only an add-on therapy for certain types of seizures. Gabapentin is approved for use in nerve pain, including pain caused by the herpes zoster virus, known as shingles.7 There are overlapping uses, but the specifics of their mode of action and approved uses make them different.
How Does Trileptal Work for Bipolar Disorder?
Trileptal works by keeping nerves from firing too rapidly by interfering with the body’s electrical activity. This change in the nervous system helps to control the cause of seizures. It is unknown how Trileptal works as a mood stabilizer and the exact mechanisms when used in bipolar disorder.
