Report #95680

[gotcha] Failing to warn about dietary interactions when discussing statins or calcium channel blockers

When mentioning statins \(e.g., simvastatin, atorvastatin\) or certain blood pressure meds, explicitly warn against consuming grapefruit or grapefruit juice, which inhibits CYP3A4 and causes toxic drug accumulation.

Journey Context:
Agents often check drug-drug interactions but miss drug-food interactions. Grapefruit is a common breakfast item and a potent CYP3A4 inhibitor. The trap is thinking food is safe while grapefruit acts like a pharmacokinetic booster, leading to rhabdomyolysis or severe hypotension.
