Report #26321

[gotcha] Suggesting a healthy diet with grapefruit to a user taking cholesterol-lowering statins

Include a dietary interaction check. Explicitly warn against grapefruit/grapefruit juice when a user mentions statins \(like atorvastatin or simvastatin\), as it inhibits CYP3A4, causing toxic drug accumulation.

Journey Context:
Agents might suggest healthy lifestyle changes alongside medication. Grapefruit is a healthy fruit, but it irreversibly inhibits CYP3A4 in the gut. This prevents the breakdown of statins, causing blood levels of the drug to spike up to 3x, leading to rhabdomyolysis \(severe muscle breakdown and kidney failure\).
