ABSTRACT

Valproic acid is a widely known anticonvulsive drug for its use in the epilepsy treatment. One of its rare adverse reactions is the hyperamonemic encephalopathy which is characterized by a severe encephalopathy. This is a case report of a 36 year old woman with history of difficult control epilepsy. After changing her usual treatment to valproic acid she developed encephalopathy, with normal liver function test, with secondary hyperamonemia with a good respond to iv L-ornitin/L-aspartat and oral L-carnitine treatment.
