[gotcha] Calculating safe Acetaminophen/Paracetamol dosage when taking over-the-counter cold and flu remedies

Always calculate the total acetaminophen/paracetamol across ALL medications. Cap at 4g/day for healthy adults, and strongly warn against stacking multi-symptom products which often contain 325-500mg per dose, leading to acute liver failure.

Journey Context:
Agents and users often check the active ingredient of the primary painkiller but overlook the 'hidden' acetaminophen in nighttime cold syrups or sinus meds. Hepatotoxicity can occur at just 7.5g/day in adults, and the antidote \(N-acetylcysteine\) has a narrow treatment window. Assuming a single-medication context is a lethal trap.
