[gotcha] Calculating Acetaminophen dosage without checking for polypharmacy in OTC cold remedies

Always explicitly warn about hidden Acetaminophen in combination OTC products \(e.g., NyQuil, DayQuil\) and calculate the cumulative daily dose, capping at 4g/day \(or 3g/day for older adults\) to prevent hepatotoxicity.

Journey Context:
Agents often calculate the dose for the pure Tylenol pill the user mentions, but miss that the user is also taking a cold/flu medication. Acetaminophen is the leading cause of acute liver failure. The fix requires the agent to ask about \*all\* OTC meds before giving a safe dosage range, as users rarely realize cold meds contain it.
