Antiepileptic drugs such as sodium valproate, lamotrigine, and levetiracetam do not affect hepatic enzyme activity and can be combined with chemotherapy drugs. Likewise, during the administration of antiepileptic drugs, it is important to regularly review the blood routine and liver and kidney functions, and check the blood drug concentration if necessary. On the one hand, monitor the effect of antiepileptic drugs and chemotherapy drugs, and on the other hand, monitor the side effects of drugs. Only in this way can the drugs give full play to both prevent tumor recurrence and antiepilepsy, and also minimize the side effects of the drugs.
