What must a transferring pharmacist write on the face of the prescription when transferring?

When a pharmacist transfers a prescription, they must clearly indicate the transfer process to ensure accurate record-keeping and communication between pharmacies. Writing "Voided" on the face of the original prescription signifies that the prescription has been canceled at the transferring pharmacy and is no longer valid there. This action protects against the risk of multiple fillings and helps maintain accountability for the prescription's status.

In contrast, other options do not serve the same purpose in indicating the transfer status of the prescription. For instance, writing the transfer date does not communicate that the original prescription is no longer valid, while noting the refill date or the patient's name does not address the transfer process itself. The action of marking a prescription as "Voided" is essential in maintaining the integrity of the patient's medication history and the regulatory requirements associated with prescription transfers.
