Massive Sulfasalazine and Paracetamol Ingestion Causing Acidosis, Hyperglycemia, Coagulopathy, and Methemoglobinemia

Abstract

Case Reports: Reports of acute toxicity following sulfasalazine ingestion are rare. A case of an acute ingestion of sulfasalazine 50 g and paracetamol 50 g resulting in severe lactic acidosis, seizures, coagulopathy, hyperglycemia, ketosis, and methemoglobinemia is reported. Despite the ingestion of a large amount of paracetamol with serum paracetamol 5486 nmol/L (844 mg/L), significant hepatotoxicity did not occur. The patient recovered fully following administration of intravenous N-acetylcysteine, methylene blue, sodium bicarbonate, and supportive therapy.
