Intravenous paracetamol toxicity in a malnourished child

We present a case of intravenous (IV) paracetamol overdose in a nutritionally malnourished child during hospital admission. A ten-fold IV paracetamol dosing error ocurred, with delayed recognition and treatment resulting in transient hepatotoxicity, with a peak alanine transaminase (ALT) of 1378 IU/L in a 3-year-old child. Our case suggests that hepatotoxicity may occur for lower doses of IV paracetamol compared to oral ingestion, especially in the malnourished, and that a dose less than 150 mg/kg of IV paracetamol should be used to define treatment following overdose in a child with potential nutritional deficiencies.
