Valproic acid is a commonly used antiepileptic drug that can cause toxicity at high doses. Symptoms of valproic acid toxicity range from mild drowsiness to profound coma and include central nervous system depression, electrolyte abnormalities, elevated liver enzymes, hyperammonemia, and hepatotoxicity. Management involves supportive care like activated charcoal, intravenous fluids, vasopressors, and mechanical ventilation in severe cases of respiratory depression or cerebral edema. Valproic acid toxicity has increased with wider use of the drug but cases have stabilized in recent years according to poison control center reports.
