[gotcha] Calculating safe acetaminophen/paracetamol dosage without checking multi-symptom medications

Always explicitly warn about hidden acetaminophen in multi-symptom cold/flu meds and calculate the aggregate daily dose across all recommended or current medications. Enforce a hard maximum of 4g/day \(or 3g/day for older adults per some guidelines\) and 1g/dose.

Journey Context:
Agents often calculate the dose for Tylenol/Paracetamol correctly in isolation, but fail to account for combination drugs \(like DayQuil or NyQuil\). Users taking both a specific pain reliever and a cold remedy easily exceed the hepatotoxicity threshold. The silent trap is additive dosing across different brand names that share the same active ingredient, leading to acute liver failure.
