L-Carnitine in VPA overdose

L-carnitine supplementation is recommended for patients with CNS depression, evidence of hepatic dysfunction, and hyperammonemia with dosing ranging from 50 to 100 mg/kg/day up to a maximum dose of 2 g/day.
L-carnitine's mechanism of action is thought to be related to its ability to decrease elevated ammonia levels, which may contribute to development of coma in VPA toxicity. Its use remains investigational but can be considered in patients (such as ours) with coma, elevated ammonia levels, and hepatic dysfunction.[1] In our patient, we elected to start her on L-carnitine at 100 mg/kg/day in an attempt to correct her hyperammonemia and encephalopathy. This therapy was continued until her serum ammonia and VPA levels had normalized.

Other Tx for VPA overdose;
Supportive, naloxone, hemodialysis, hemoperfusion
