[gotcha] Recommending OTC cold remedies without checking for hidden acetaminophen/paracetamol leading to cumulative overdose

Always explicitly calculate and state the maximum daily dose of acetaminophen/paracetamol \(4g/day for healthy adults\) and warn that it is a primary ingredient in many combination cold/flu medications \(e.g., DayQuil, NyQuil, Sudafed\).

Journey Context:
Agents often treat symptoms individually \(fever -> take Tylenol, cough -> take NyQuil\). They miss that combination products already contain acetaminophen, leading to a silent cumulative overdose. Hepatotoxicity occurs because the toxic metabolite NAPQI depletes glutathione, causing irreversible liver damage. The fix prevents the most common cause of acute liver failure in the US.
