Report #21252

[gotcha] Recommending cold/flu remedies without checking for hidden acetaminophen \(paracetamol\) leading to hepatotoxicity

Always explicitly warn about the maximum daily dose \(4g/24h for healthy adults, lower for elderly/hepatic impairment\) and cross-check if the user is taking combination products \(e.g., DayQuil, NyQuil, Theraflu\) that contain acetaminophen before suggesting standalone acetaminophen.

Journey Context:
Agents often correctly state the safe single-dose limit for acetaminophen but fail to account for patients taking multiple over-the-counter combination meds. Acetaminophen is the leading cause of acute liver failure in the US because it is silently included in hundreds of common cold remedies. Users accidentally double-dose, leading to delayed, asymptomatic hepatotoxicity that becomes lethal if untreated.
