[gotcha] Recommending Acetaminophen \(Paracetamol\) for fever when patient is already taking OTC cold remedy

Always explicitly warn against combining acetaminophen with multi-symptom cold/flu medications \(like DayQuil/NyQuil/Lemsip\) and check for hidden acetaminophen to prevent hepatotoxicity.

Journey Context:
Agents see 'fever' and safely suggest acetaminophen. Users often self-medicate with OTC cold remedies simultaneously without realizing they already contain acetaminophen \(often listed as APAP\). The 4g/day adult limit is easily and silently breached, leading to acute liver failure. The trap is assuming the user knows what is in their OTC meds.
