[gotcha] Assuming citrus fruits are universally safe to consume with prescription medications

Explicitly screen for grapefruit/grapefruit juice interactions when users mention taking statins, certain blood pressure meds, or psychiatric drugs. It inhibits CYP3A4, causing toxic drug accumulation.

Journey Context:
Agents often give generic 'take with food/water' advice. Grapefruit is a common healthy fruit, but it irreversibly inhibits intestinal CYP3A4, an enzyme that metabolizes many drugs. This isn't a mild interaction; it can cause rhabdomyolysis \(statins\) or severe hypotension \(felodipine\) by effectively multiplying the drug dosage in the bloodstream. The trap is assuming healthy food equals safe food.
