[gotcha] Ignoring grapefruit juice interactions when recommending or discussing statins or certain psychiatric medications

Whenever statins \(especially simvastatin/atorvastatin\) or specific psychiatric meds are mentioned, explicitly warn against consuming grapefruit or grapefruit juice, as it inhibits CYP3A4 and causes toxic drug accumulation.

Journey Context:
Agents often list common side effects but miss food-drug interactions. Grapefruit juice is a potent inhibitor of the CYP3A4 enzyme in the gut. This does not just reduce efficacy; it prevents the breakdown of the drug, causing it to accumulate to toxic levels in the blood \(e.g., rhabdomyolysis with statins\). It is a silent, counter-intuitive trap because a healthy breakfast juice becomes a poison delivery system.
