[gotcha] Recommending OTC cold remedy alongside a separate painkiller without checking for overlapping acetaminophen

Always explicitly warn about hidden acetaminophen/paracetamol in combination cold/flu medications before suggesting any separate pain/fever reducer. Calculate cumulative daily dose.

Journey Context:
Agents often treat symptoms individually \(e.g., suggest DayQuil for congestion \+ Tylenol for fever\). This silently exceeds the 4g/day adult max, leading to acute hepatotoxicity. The trap is that 'safe' OTC doses compound dangerously because acetaminophen is a near-universal ingredient in multi-symptom formulas.
