[gotcha] Recommending a cold remedy alongside a separate painkiller without checking for overlapping active ingredients

Always explicitly warn about Acetaminophen/Paracetamol stacking across OTC medications before suggesting any combination, capping at 4000mg/day for adults.

Journey Context:
Agents often treat symptoms individually \(e.g., recommending a decongestant for a runny nose and a separate painkiller for a headache\). Most multi-symptom OTC cold medications already contain acetaminophen. Suggesting additional Tylenol leads to silent, cumulative hepatotoxicity that the user will not feel until severe liver damage occurs.
