Weight-based acetaminophen dosing for all ages.
Adults: 500–1000 mg every 4–6 hours, max 4 g/day. Children: 15 mg/kg/dose, max 75 mg/kg/day. Patients < 50 kg: use weight-based dosing even in adults. Hepatotoxicity risk increases above 4 g/day or with chronic alcohol use. Paracetamol is hidden in many combination products – check all medications for total daily intake.
