[gotcha] Recommending the maximum daily dose of paracetamol/acetaminophen \(4g/day\) for mild fever reduction

Use the lowest effective dose for fever; do not default to the maximum 1000mg per dose or 4g daily limit, especially in frail, fasting, or elderly patients where the threshold for hepatotoxicity is lower.

Journey Context:
Agents often map 'severe' to 'max dose'. However, paracetamol's therapeutic index is narrow, and hepatotoxicity is the leading cause of acute liver failure. Lower doses \(500-650mg\) are often sufficient for fever and provide a wider safety margin against accidental double-dosing with combination cold medicines.
