Abstract

Valproic acid is increasingly used in the treatment of epilepsy, and also prescribed for bipolar affective disorders, schizoaffective disorders, schizophrenia and migraine prophylaxis. Valproic acid intoxication with suicide attempt is a relatively common clinical problem that can result in coma, respiratory depression, pancytopenia, hemodynamic instability and death. The drug's relatively low molecular weight, small volume of distribution and saturable protein-binding render it potentially amenable to exracorporeal removal (hemodialysis, hemoperfusion or hemofiltration ), but published experience is scarce. We describe a case report involving valproic acid intoxication with ingestion of ethanol, who was successfully treated with charcoal hemoperfusion. With this treatment the half-life of valproic acid was reduced with rapid lowering of valproic acid levels and clinical improvement. Based on our experience in this patient and a review of previously reported cases, charcoal hemoperfusion should be considered for serious valproic acid intoxication because free as well as bound drug fractions are eliminated via this technique.
