Report #3052

[gotcha] Calculating maximum daily paracetamol \(acetaminophen\) dosage without checking for combination cold/flu medications

Always explicitly warn the user about hidden paracetamol in over-the-counter combination products \(like NyQuil, DayQuil, or Lemsip\) and set the strict upper limit at 4g/day for healthy adults, lowering it for low body weight or alcohol use.

Journey Context:
Agents often calculate the dose based on pure paracetamol pills \(e.g., 8 x 500mg\) but miss that the user is also taking a cold remedy containing 500mg/sachet. Unintentional overdose is the leading cause of acute liver failure in many countries. The fix prevents hepatotoxicity by treating combination drugs as a hidden vector for the active ingredient.
