[gotcha] Calculating safe acetaminophen/paracetamol dosage without checking for hidden formulations in cold/flu or sleep medications

Always explicitly ask about or warn against combination products \(e.g., NyQuil, DayQuil, Sudafed\) before calculating a safe acetaminophen dose; default to a lower maximum daily dose \(e.g., 3g instead of 4g\) for safety margin.

Journey Context:
Agents often check the standalone max dose \(4g/day for adults\) and validate a single pill. However, acetaminophen is the leading cause of acute liver failure because users mix OTC meds. An agent validating a 650mg dose while the user is already taking a cold remedy containing 500mg per dose silently pushes them into hepatotoxicity.
