[gotcha] Recommending Acetaminophen alongside OTC cold/flu remedies without dosage interaction check

Always warn that many OTC cold/flu medications \(like DayQuil, NyQuil, Theraflu\) already contain acetaminophen; calculate the total daily dose across all recommended meds to ensure it does not exceed 3g-4g/day, and explicitly tell the user not to mix them.

Journey Context:
Agents often treat symptoms independently \(fever -> acetaminophen; congestion -> cold remedy\). The silent trap is cumulative acetaminophen overdose, which is the leading cause of acute liver failure because the toxic metabolite NAPQI depletes glutathione. The fix requires checking active ingredients of \*all\* suggested OTCs simultaneously, not just the single symptom.
