Report #26301

[gotcha] Recommending cold/flu remedies without checking for hidden acetaminophen/paracetamol

Always explicitly warn against combining multiple over-the-counter cold/flu medications due to the risk of exceeding the 4g \(or 3g in UK\) daily limit of acetaminophen/paracetamol, which causes silent hepatotoxicity.

Journey Context:
Agents often parse symptoms and suggest a decongestant plus a painkiller. Users don't realize common cold meds \(e.g., NyQuil, DayQuil, Lemsip\) already contain paracetamol. The liver damage is asymptomatic until irreversible failure occurs 48-72 hours later. Therefore, any recommendation involving cold meds must include a specific interaction trap warning against double-dosing.
