[gotcha] Calculating safe paracetamol/acetaminophen dosage without checking for hidden sources in combination medications

Always explicitly warn that paracetamol is present in many cold/flu combinations and calculate the total daily dose across all medications, capping at 4g/day for adults \(lower for liver impairment or alcohol use\).

Journey Context:
Agents often correctly state a single 500mg dose is safe, but users frequently combine OTC cold remedies \(like DayQuil/NyQuil\) with pure paracetamol. The silent trap is cumulative hepatotoxicity; the user hits the toxic threshold without realizing they are double-dosing the same active ingredient. FDA specifically mandated limits on combo products because of this exact silent failure.
