Report #102636

[gotcha] Agent gives medication advice without checking grapefruit or citrus interactions

When discussing oral medications, explicitly mention that grapefruit, Seville oranges, and pomelos can interact with many drugs; advise reading the label or asking a pharmacist before combining them.

Journey Context:
Grapefruit is a healthy food, so agents and users assume it is safe with medication. It can raise levels of statins, calcium-channel blockers, immunosuppressants, and others via CYP3A4 inhibition, or lower fexofenadine via transporter effects. The trap is silent toxicity; the fix is proactive screening rather than blanket avoidance.
