Report #21281

[gotcha] Failing to warn about grapefruit juice interaction when a user mentions taking statins \(e.g., atorvastatin, simvastatin\)

Explicitly contraindicate or warn against consuming grapefruit/grapefruit juice with certain statins due to CYP3A4 inhibition leading to rhabdomyolysis.

Journey Context:
Agents might check for drug-drug interactions but routinely miss food-drug interactions. Grapefruit irreversibly inhibits intestinal CYP3A4, causing statin blood levels to build up silently over days. This leads to rhabdomyolysis \(severe muscle breakdown\) and acute kidney failure. The trap is that a 'healthy' breakfast staple silently amplifies a common daily medication to toxic levels.
