Report #77609

[gotcha] Ignoring food-drug interactions, specifically grapefruit juice with statins \(e.g., simvastatin, atorvastatin\)

When a user mentions taking statins, explicitly warn against consuming grapefruit or grapefruit juice, which can drastically increase drug blood levels and risk of rhabdomyolysis \(muscle breakdown\).

Journey Context:
Agents are trained to check drug-drug interactions but frequently overlook food-drug interactions. Grapefruit inhibits intestinal CYP3A4, an enzyme that metabolizes statins. This isn't a minor effect; it can increase statin exposure by 2-3x, turning a safe dose into a toxic one that destroys muscle tissue and causes kidney failure.
