We report a case of poisoning resulting from the use of Chinese proprietary
medicines (CPM) containing anticonvulsants phenytoin, carbamazepine and va
lproate. The manufacturer's information leaflets did not mention any of the
se prescription drugs. As a consequence, the patient was admitted comatose
due to severe phenytoin poisoning. We are not aware of any reported case of
severe poisoning due to CPM adulterated with anticonvulsants and this is p
ossibly the first case.
