What should pharmacy (A) do when the patient chooses to fill a prescription at pharmacy (B) instead?

In situations where a patient decides to fill a prescription at a different pharmacy, the best course of action is to recognize that the original pharmacy, in this case pharmacy (A), cannot directly transfer the prescription to pharmacy (B) without certain protocols being followed. The options involving calling or faxing the prescription imply that pharmacy (A) could facilitate a transfer, which is not typically permitted without proper authorization or clearance based on state and federal regulations.

Providing a copy of the prescription to the patient is also a problematic action because a pharmacy can only provide a copy under specific circumstances, such as if the prescription has been filled or if there's been an explicit request for a copy for personal use, but it does not constitute transferring the prescription for fulfillment at another pharmacy.

Ultimately, if the patient chooses to go elsewhere, the appropriate action for pharmacy (A) is to inform the patient that they may take their prescription to pharmacy (B) and allow them to manage the transfer process. This ensures compliance with legal regulations governing prescription transfers and patient confidentiality. Thus, "None of the above" is aligned with the proper adherence to pharmaceutical laws and the ethical treatment of patient prescriptions.
