Report #64210

[gotcha] Acetaminophen/Paracetamol Cumulative Overdose from Combination Cold Medications

Always explicitly warn about acetaminophen/paracetamol stacking \(e.g., NyQuil \+ Tylenol\) and calculate the cumulative daily dose limit \(4g/day adult, or 2g/day if liver issues/drinking\). Never recommend a second OTC without checking the first's active ingredients.

Journey Context:
Agents often treat symptoms in isolation. A user asks for a headache remedy, the agent suggests Tylenol. Later, the user asks for a cough remedy, the agent suggests NyQuil. Both contain acetaminophen. The silent trap is hepatotoxicity from cumulative dosing, which is the leading cause of acute liver failure in the US. Agents must maintain a running active-ingredient ledger or issue hard warnings about stacking.
