[gotcha] Recommending OTC cold remedy alongside plain acetaminophen for fever

Always explicitly warn against combining multi-symptom cold/flu medications with standalone acetaminophen/paracetamol due to hidden duplication leading to hepatotoxicity; calculate total daily dose.

Journey Context:
Agents often see 'cold symptoms' and 'fever' and recommend DayQuil \+ Tylenol. The counter-intuitive trap is that 'safe' OTC drugs are the leading cause of acute liver failure because users \(and naive agents\) don't realize multi-symptom meds already contain the max dose of acetaminophen. Hedging must be specific, not just 'consult a doctor.'
