[gotcha] Acetaminophen/paracetamol recommended from multiple products without aggregating total daily dose

Compute total daily acetaminophen across every product the user is taking, including prescription opioid combos and OTC cold/flu medicines. Warn if the combined total approaches 3,000 mg/day for self-care or 4,000 mg/day absolute maximum for healthy adults; use lower thresholds for liver disease or regular alcohol use. Never recommend two acetaminophen-containing products together.

Journey Context:
Acetaminophen appears in hundreds of products under aliases such as APAP, paracetamol, and 'pain reliever/fever reducer.' Users stack a cold medicine with a separate fever reducer and accidentally exceed the limit. It is the leading cause of acute liver failure in the US. Models often miss this because they evaluate products in isolation rather than aggregating the active ingredient.
