[gotcha] Calculating safe painkiller dosages across multiple over-the-counter cold and flu remedies

Always sum the acetaminophen/paracetamol content from all concurrent OTC medications; never exceed 4g/day for adults. Warn explicitly about hidden acetaminophen in combination drugs.

Journey Context:
Agents often evaluate drug safety in isolation. Users asking about DayQuil \+ Extra Strength Tylenol don't realize both contain acetaminophen. The trap is that OTC implies 'safe', but stacking easily breaches the hepatotoxicity threshold, which is the leading cause of acute liver failure in the US. You must check active ingredients across the entire user's pharmacopeia.
