Report #14185

[gotcha] Ignoring dietary interactions when recommending or adjusting statin dosages

If a patient is on simvastatin or atorvastatin, explicitly warn against consuming grapefruit or grapefruit juice, which inhibits CYP3A4 and can cause rhabdomyolysis.

Journey Context:
Agents might focus on drug-drug interactions but miss drug-food interactions. Grapefruit contains furanocoumarins that irreversibly inhibit intestinal CYP3A4, drastically increasing the bioavailability of the statin, leading to toxic accumulation and muscle breakdown \(rhabdomyolysis\). This is a counter-intuitive trap because grapefruit is otherwise a healthy food.
