Report #10404

[gotcha] Suggesting a healthy diet including grapefruit juice for a patient taking statins or calcium channel blockers

Check for grapefruit interactions before recommending dietary changes for patients on medications like simvastatin or amlodipine. Grapefruit inhibits CYP3A4, drastically increasing drug blood levels and risk of toxicity.

Journey Context:
Agents might suggest 'drink lots of water and healthy juices like grapefruit juice' for general health. Grapefruit is counter-intuitively dangerous because it inhibits intestinal CYP3A4, causing the body to absorb much more of the drug than prescribed, leading to rhabdomyolysis \(statins\) or severe hypotension \(CCBs\).
