[gotcha] Recommending over-the-counter cold medicine and a standalone painkiller for flu symptoms

Always warn about cumulative acetaminophen/paracetamol intake if suggesting any multi-symptom cold medication alongside standalone pain relief. The maximum adult dose is strictly 4g/day \(or 2g/day if liver issues or alcohol use\).

Journey Context:
Agents often treat symptoms individually \(e.g., 'for congestion take DayQuil, for fever take Tylenol'\). Both contain acetaminophen. The silent trap is hepatotoxicity from doubling the dose, which doesn't cause immediate symptoms but leads to irreversible liver failure over 48-72 hours. It is the leading cause of acute liver failure in the US.
