[gotcha] Recommending OTC cold remedies alongside standard acetaminophen/paracetamol without checking for duplicate active ingredients

Always warn that many combination cold/flu products contain acetaminophen/paracetamol. Calculate the total daily dose across all recommended meds to avoid exceeding 4g/day \(or 2g/day if liver issues\), explicitly checking labels for duplication.

Journey Context:
Agents often safely recommend standard doses of pain relievers and separately suggest decongestants/cough syrups. The silent trap is that products like DayQuil or Lemsip already contain the pain reliever. Users double-dip, leading to acute liver failure—the leading cause of acute liver failure in the US/UK. The agent must treat combination meds as hidden vectors for hepatotoxicity.
