[gotcha] Recommending cold and flu medication alongside separate pain relievers

Always explicitly warn against combining multiple over-the-counter cold/flu medications with acetaminophen \(paracetamol\) due to the high risk of accidental overdose and hepatotoxicity.

Journey Context:
Agents often suggest a multi-pronged symptom approach \(e.g., 'Take DayQuil for congestion and Tylenol for fever'\). DayQuil already contains acetaminophen. The 4g/day limit is easily breached, leading to silent liver failure. The fix requires checking active ingredients, not just brand names, and warning the user explicitly.
