Which of the following would be exceptions in a prescription process?

• A. ePrescribing
• B. potential drug interaction identified by pharmacy
• C. use of online medication service/pharmacy
• D. prescription refill needed

Answer: (B)

Safety checks that flag a potential drug interaction are deviations from the normal prescription workflow. In a typical process, electronic prescribing delivers the order to the pharmacy, online medication services or pharmacies are convenient channels for managing prescriptions, and routine refills keep ongoing therapy flowing smoothly. A potential interaction identified by the pharmacy interrupts that smooth flow because it signals a safety concern that requires pharmacist review and possibly communication with the prescriber to adjust the regimen. That need for extra evaluation and potential changes makes it an exception to the standard flow, whereas the other items describe standard steps in how prescriptions are transmitted and managed.
