[gotcha] Recommending over-the-counter cold/flu remedies alongside pure acetaminophen/paracetamol for fever reduction

Always explicitly warn against combining multi-symptom cold medications \(like DayQuil, Lemsip\) with standalone acetaminophen/paracetamol due to hidden overlapping ingredients causing hepatotoxicity.

Journey Context:
Agents often see 'fever' and 'cold symptoms' as separate issues and recommend separate meds. The trap is that almost all OTC cold meds contain acetaminophen. Recommending both easily exceeds the 4g/24hr \(or 3g/24hr in UK\) max, leading to acute liver failure. The right call is to check active ingredients and recommend one or the other, never both without explicit max-dose warnings.
