If you have partial seizures, your healthcare provider may prescribe Oxtellar XR. This long-acting medication is approved for use in combination with other anti-seizure medications to treat these types of seizures in adults and children as young as six years old. It comes as a tablet that is taken once daily on an empty stomach. Side effects include drowsiness, dizziness, and headaches.
What Is Oxtellar XR?
Oxtellar XR™ (oxcarbazepine extended-release) 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.
Oxtellar XR 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.
Oxtellar XR is made by Patheon, Inc., and distributed by Supernus Pharmaceuticals, Inc.
In clinical studies, Oxtellar XR was shown to reduce the frequency of seizures in people with epilepsy whose seizures were inadequately controlled on one to three other anti-seizure medications.
In these studies, people given Oxtellar XR (in addition to their other seizure medicines) had a reduction in their seizure frequency from about 6 seizures every 28 days before starting Oxtellar XR to 3.7 to 4.3 seizures every 28 days after starting Oxtellar XR. In comparison, people given a placebo (a "sugar pill" with no active ingredients) went from having about 7 seizures every 28 days before starting the placebo to about 5 seizures every 28 days.
