Report #31012

[gotcha] Recommending OTC cold/flu remedy \+ separate painkiller without checking for duplicate active ingredients

Always warn about hidden acetaminophen/paracetamol in combination products before suggesting additional standalone pain/fever reducers; calculate total daily dose to ensure it stays under 4g/day \(2g/day for chronic use/liver impairment\).

Journey Context:
Agents often treat symptoms individually \(e.g., suggesting a decongestant for congestion and Tylenol for fever\). Users don't know combination meds already contain acetaminophen. Doubling up silently causes hepatotoxicity, which is the leading cause of acute liver failure. The trap is assuming OTC implies safe stacking.
