[Haemodialysis, L-carnitine therapy and valproic acid overdose].

We report the case of a severe valproic acid poisoning in a 36-year-old man. In front of a high serum concentration of valproic acid at the admission, haemodialysis was initiated to decrease serum valproic acid concentration. A L-carnitine therapy (50 mg/kg per day) was also started. A cerebral oedema appeared at the third day, but the patient recovered without any sequela.
