[gotcha] Omitting diet interactions when listing drug administration instructions

Always warn about grapefruit/grapefruit juice interactions for statins, calcium channel blockers, and certain psychiatric drugs. It inhibits CYP3A4, causing toxic drug accumulation.

Journey Context:
Patients and agents often view juice as harmless hydration. Grapefruit juice irreversibly blocks intestinal CYP3A4, meaning more of the drug enters the bloodstream rather than being metabolized. A single glass can increase statin blood levels by up to 150%, leading to rhabdomyolysis.
