Isoniazid toxicity presenting as seizures and metabolic acidosis.
The presenting signs and symptoms of isoniazid toxicity are discussed, with a review of the complications and management of this metabolic encephalopathy with B6 pyridoxine. This study supports previous studies in finding that ingestion of more than 80 mg/kg body weight produces severe central nervous system symptoms that are rapidly reversed with intravenous administration of pyridoxine.
