For people 17 years of age and older, the starting dose is usually 600 mg daily. For people 6 to 17 years of age, the dose will be calculated based on the person’s body weight.
  • Oxtellar XR is taken by mouth once daily on an empty stomach. Swallow tablets whole with water. Take Oxtellar XR at the same time each day.
  • Do not cut, crush, or chew the tablets.
  • It is not interchangeable with immediate-release oxcarbazepine products, such as Trileptal, without guidance from a healthcare provider.
  • Missing doses may increase seizure risk.
  • Contact your healthcare provider if you have trouble swallowing tablets.
  • Avoid driving or operating machinery until you know how the medication affects you. The most common side effects are dizziness and sleepiness.
