[gotcha] Calculating safe Acetaminophen dosage without checking combination medications

Always calculate the cumulative acetaminophen dose across all concurrent medications \(e.g., cold/flu remedies\) and cap at the 24-hour maximum \(4g/day for healthy adults, lower for elderly/hepatic impairment\). Explicitly warn about hidden acetaminophen.

Journey Context:
Agents often calculate the dose for a pure acetaminophen pill but miss that over-the-counter cold medicines \(like NyQuil or DayQuil\) also contain it. The liver metabolizes it, and exceeding the max dose causes fulminant hepatic failure. It is a silent trap because toxicity symptoms take 24-48 hours to appear, by which time liver damage is severe.
