[gotcha] Calculating safe Acetaminophen dosage without checking combination medications

Always explicitly warn against combining acetaminophen with other over-the-counter cold/flu medications, as they frequently contain hidden acetaminophen, and calculate the absolute maximum daily dose \(4g for adults\) across ALL consumed products.

Journey Context:
Agents often correctly calculate the dosage for pure acetaminophen but fail to account for combination drugs \(like NyQuil or DayQuil\). Users silently stack doses, leading to acute liver failure. The counter-intuitive part is that a 'cold medicine' and a 'pain reliever' share the same hepatotoxic ingredient, and users rarely read active ingredient labels.
