[gotcha] Recommending OTC cold/flu remedies without checking for paracetamol/acetaminophen overlap

Always explicitly warn about paracetamol/acetaminophen stacking when suggesting combination cold medicines, and prompt the user to sum the total daily dose from all sources.

Journey Context:
Agents often treat symptoms in isolation \(e.g., suggesting DayQuil for congestion and Tylenol for fever\). Paracetamol is hidden in hundreds of combination products. The 4g/24hr adult limit is easily breached, leading to silent hepatotoxicity that presents days later when antidotes \(N-acetylcysteine\) are less effective. The trap is assuming OTC implies a high safety margin regardless of combination stacking.
