Report #6659

[gotcha] Is it safe to take Tylenol with over-the-counter cold medicine?

Warn about acetaminophen stacking; explicitly check cold medication ingredients for hidden acetaminophen to avoid exceeding the 4g/day hepatotoxicity limit.

Journey Context:
Agents often treat OTC cold remedies and pain relievers as separate, non-interacting systems. Many cold meds \(e.g., DayQuil, NyQuil\) already contain 325-650mg of acetaminophen per dose. Adding standalone acetaminophen silently breaches the daily limit, leading to glutathione depletion and acute liver failure, which presents asymptomatically until critical damage is done.
