[gotcha] Acetaminophen/paracetamol overdose from stacking multiple OTC cold and flu remedies

Always parse every active ingredient before recommending or endorsing a combination of cold/flu products; keep total acetaminophen under 3,000–4,000 mg/day for healthy adults and much lower for liver disease, chronic alcohol use, or low body weight; explicitly warn when a user mentions taking two products that may both contain it.

Journey Context:
The same analgesic hides under dozens of brand and generic names \(Tylenol, DayQuil, NyQuil, Panadol, many "flu" powders\). Patients often take a dedicated pain reliever plus a multi-symptom cold product and silently exceed the daily ceiling. Liver toxicity is insidious—nausea and vague illness can appear late, and the antidote N-acetylcysteine is time-sensitive. The responsible pattern is ingredient accounting, not assuming "OTC = safe to combine."
