[gotcha] Recommending over-the-counter cold/flu remedy alongside acetaminophen/paracetamol for fever reduction

Always explicitly warn against combining acetaminophen with multi-symptom cold medications \(e.g., DayQuil, NyQuil, Lemsip\) due to hidden acetaminophen causing hepatotoxicity. Check active ingredients.

Journey Context:
Agents often try to be helpful by suggesting a multi-symptom reliever plus a dedicated fever reducer. This silently doubles the dose. The liver processes acetaminophen via CYP2E1 to NAPQI; glutathione depletion leads to fatal liver necrosis. It is the leading cause of acute liver failure in the US, and the trap is invisible to users who don't read inactive/combination ingredient lists.
