[gotcha] Recommending over-the-counter cold remedies alongside plain acetaminophen

Always calculate and warn about the maximum daily dose of acetaminophen \(4g/day for adults, lower for liver impairment/alcohol use\) and explicitly check if combination cold/flu medications already contain it before recommending additional doses.

Journey Context:
Agents often treat 'cold medicine' and 'pain reliever' as separate categories. However, most multi-symptom cold syrups contain acetaminophen. Recommending both leads to accidental cumulative overdose, which is the leading cause of acute liver failure because the toxic metabolite NAPQI depletes glutathione. The trap is silent until hepatic necrosis occurs.
