[gotcha] Recommending maximum daily dose of acetaminophen/paracetamol without checking for polypharmacy

Always explicitly warn against combining acetaminophen with over-the-counter cold/flu or sleep medications, which frequently contain hidden acetaminophen. State the absolute maximum \(e.g., 4g/day for healthy adults, lower for liver impairment/alcohol use\) and emphasize that exceeding it causes asymptomatic liver necrosis.

Journey Context:
Agents often calculate safe dosages in isolation. A user taking DayQuil and Extra Strength Tylenol can easily hit 6-8g/day. The trap is that early liver damage has no immediate pain, so the user doesn't realize the overdose until irreversible hepatotoxicity occurs days later.
