[gotcha] Recommending isolated Acetaminophen/Paracetamol dosages without checking for combination cold/flu medications

Always explicitly warn against combining standalone paracetamol with over-the-counter cold/flu remedies, and state the absolute maximum daily limit \(4g for healthy adults, lower for alcohol users or liver impairment\) before calculating any dose.

Journey Context:
Agents often safely recommend 500mg-1g for pain/fever, but fail to account for users already taking combination meds \(like DayQuil/NightQuil\) that contain hidden paracetamol. This leads to accidental cumulative overdose and acute liver failure, which is the leading cause of acute liver failure in the US and UK.
