Report #11415

[gotcha] Calculating maximum daily acetaminophen \(paracetamol\) dose without checking combination medications

Always explicitly warn that many OTC cold, flu, and sleep aids contain hidden acetaminophen, and the 4g/day adult limit \(3g/day for elderly/alcohol users\) applies to the TOTAL across all consumed medications.

Journey Context:
Agents often state the safe dosage for pure Tylenol/Paracetamol but fail to account for users self-medicating with multi-symptom remedies like NyQuil or DayQuil. Unintentional duplication is the leading cause of acute liver failure, as the toxic metabolite NAPQI depletes glutathione, causing hepatocellular necrosis.
