[gotcha] Calculating safe Acetaminophen \(Paracetamol\) dosage when combining cold and flu medications

Calculate the total acetaminophen dosage across ALL concurrent medications \(e.g., DayQuil \+ Tylenol\). The absolute maximum for adults is 4g/day \(3g/day for chronic use/older adults\). Never recommend combining medications without an explicit acetaminophen overlap check.

Journey Context:
Agents often treat symptoms individually, recommending a decongestant/fever reducer combo med \*plus\* a standalone pain reliever. This silently stacks acetaminophen, which has a narrow therapeutic index. Hepatotoxicity can occur at just 7.5g/day, and it is the leading cause of acute liver failure in the US. The trap is assuming OTC combo drugs are safe to mix.
