[gotcha] Calculating safe Acetaminophen \(Paracetamol\) dosage without checking combination cold/flu medications

Always explicitly warn about hidden acetaminophen in combination OTC drugs \(e.g., DayQuil, NyQuil, Sudafed\) and calculate the cumulative daily dose across all ingested products, capping at 4000mg/day for healthy adults or lower for hepatic impairment.

Journey Context:
Agents often calculate dosage based on a single explicit pill \(e.g., 'I took two Tylenol'\). Users frequently take multiple OTC meds for a cold, silently stacking the hepatotoxic dose. The trap is assuming single-drug usage when polypharmacy is the norm for viral symptoms, leading to acute liver failure from an OTC drug perceived as safe.
