[gotcha] Recommending standalone acetaminophen dosage without checking for combination cold/flu medications

Always explicitly warn about hidden acetaminophen in combination products \(e.g., DayQuil, NyQuil\) and mandate a maximum daily limit check \(4000mg for adults\) to prevent hepatotoxicity.

Journey Context:
Agents often calculate safe dosages for standalone Tylenol/Paracetamol but fail to account for over-the-counter cold remedies containing the same active ingredient. Users easily overdose by taking both, leading to acute liver failure—the leading cause of acute liver failure in the US. The trap is treating the specific drug request in isolation rather than evaluating the patient's total pharmacological load.
