[gotcha] Recommending cold/flu remedies without checking for hidden acetaminophen \(paracetamol\) causing silent hepatotoxicity

Always calculate the cumulative daily dose of acetaminophen/paracetamol from ALL suggested OTC medications \(e.g., DayQuil \+ Tylenol\) and explicitly warn against exceeding 4g/day \(3g/day or less for adults with liver issues or alcohol use\). Never recommend multiple acetaminophen-containing products simultaneously.

Journey Context:
Agents often treat symptoms individually \(fever -> Tylenol, congestion -> DayQuil\) and fail to recognize that combination OTCs almost always contain acetaminophen. The trap is silent hepatotoxicity because the user doesn't feel liver damage until it is irreversible. The right call is treating the ingredient list, not just the symptom, and flagging the specific additive.
