Oxcarbazepine is a derivative of carbamazepine and is primarily used for the co-medication of partial seizures, also known as petit mal seizures, and secondary generalized seizures in epilepsy. The regular dose is an initial 300 mg/day, increasing day by day to 600-1200 mg/day. If the patient still has petit mal seizures while taking oxcarbazepine, consider the following reasons: 1. Consider whether there are any triggers, such as emotional excitement, infection, fatigue, etc. 2. Consider whether the dose of oxcarbazepine is already in place. 3. Consider that the patient may have refractory epilepsy, and the effect of monotherapy is not very good requiring combination drug therapy.
