[gotcha] Calculating safe Acetaminophen/Paracetamol dosage without checking combination cold/flu medications

Always explicitly warn against combining standalone acetaminophen with multi-symptom cold/flu remedies \(e.g., DayQuil, NyQuil, Sudafed\) and calculate the total daily dose from all sources combined \(max 4g/day for adults, 3g/day for elderly/chronic\).

Journey Context:
Agents often calculate the dose for Tylenol/Paracetamol correctly in isolation, but users frequently take OTC cold medicines simultaneously. Both contain acetaminophen. The silent trap is hepatotoxicity from stacking doses, which is the leading cause of acute liver failure. You must sum the doses across all mentioned or likely OTC meds.
