Oxcarbazepine is capable of treating and relieving epilepsy symptoms, but it does not provide a cure. Epilepsy is a neurological disease caused by brain nerve disorders or abnormal discharges, and has a high chance of recurrence, so it usually requires continuous medication control and cannot be cured by a single drug. Oxcarbazepine is usually used for epilepsy complex partial seizures and generalized tonic clonic seizures, and can also be used as an adjunctive therapeutic drug for refractory epilepsy; it can also be used for trigeminal neuralgia that is intolerant to or ineffective in the treatment of carbamazepine; and it also has a certain degree of efficacy for affective psychotic disorders. During the use of oxcarbazepine, it may cause adverse reactions, such as dizziness, headache, diplopia. Ataxia can occur after an overdose of the drug. Blurred vision, nausea, drowsiness, rhinitis, flu-like syndrome, dyspepsia, skin rashes and coordination disorders occur in a small number of patients after use, and it is recommended to stop the drug immediately. For the treatment of epilepsy, it is generally recommended to choose medication according to the cause and symptoms of the seizure as prescribed by the doctor, and to have regular checkups.
