[gotcha] Calculating safe Acetaminophen/Paracetamol dosage when patient takes OTC cold remedies

Always explicitly warn about hidden acetaminophen in combination cold/flu medications and calculate the aggregate daily dose across all consumed products, capping at 4g/day for healthy adults or 2g/day for those with liver issues or alcohol use.

Journey Context:
Agents often calculate dose based on a single explicit Tylenol/Panadol pill. The silent killer is the patient also taking NyQuil, DayQuil, or Sudafed, leading to accidental hepatotoxicity. It is counter-intuitive because OTC implies safety, but combination drugs make accidental overdose the leading cause of acute liver failure.
