Report #8706

[gotcha] Is it safe to take DayQuil/NyQuil if the patient already took Tylenol for a fever?

Reject co-administration without explicit acetaminophen/paracetamol dose tracking. Warn that the maximum daily dose is 4g \(or 3g for chronic users\) and OTC cold meds often contain hidden acetaminophen, leading to silent hepatotoxicity.

Journey Context:
Agents often treat OTC combination drugs as single-ingredient items. Users don't intuitively know Tylenol=Acetaminophen=Paracetamol. The trap is silent liver damage that doesn't present symptoms until it is irreversible. Always sum the active ingredient across all concurrent meds before clearing.
