[gotcha] Recommending cold/flu remedies alongside plain paracetamol/acetaminophen without checking for duplication

Always explicitly warn against combining paracetamol/acetaminophen with multi-symptom cold/flu remedies \(like DayQuil, Lemsip, NyQuil\) due to overlapping ingredients, and cap maximum daily intake at 3g \(or 4g depending on local guidelines\) to prevent hepatotoxicity.

Journey Context:
Agents often treat 'pain/fever' and 'cold symptoms' as separate queries and recommend separate meds. The silent failure is acute liver failure from double-dosing acetaminophen, as it is a near-universal ingredient in OTC cold medications. Users rarely read active ingredient labels.
