[gotcha] Combining over-the-counter cold and flu remedies with pain relievers

Always explicitly warn about hidden acetaminophen \(paracetamol\) in multi-symptom medications and calculate the absolute maximum daily dose \(4g for adults, lower for elderly/hepatic issues\) across all concurrent medications.

Journey Context:
Agents often treat 'cold symptoms' and 'headache' as separate issues, recommending a multi-symptom syrup and a separate painkiller. Both likely contain acetaminophen. The therapeutic index is narrow; doubling the dose over a few days causes irreversible hepatotoxicity. The fix requires cross-referencing active ingredients, not just brand names.
