What must the transferring pharmacy write on the face of a prescription during a transfer?

In the context of transferring a prescription, the transferring pharmacy must write "Void" on the face of the original prescription. This is essential as it indicates that the original prescription is no longer valid and ensures that the medication cannot be dispensed again from that original document.

The action of marking the prescription as "Void" serves to inform all parties involved, including pharmacy staff and other healthcare providers, that the prescription has been transferred to another pharmacy. This helps maintain clear records and prevents potential confusion regarding the prescription's status.

Using "Transfer," "Cancel," or "Notify" would not accurately convey the status of the original prescription. "Transfer" could imply that the prescription remains valid at the transferring pharmacy, which is not the case once it has been handed over. "Cancel" could suggest that the prescription is entirely nullified without indicating that the prescription was transferred. "Notify" does not provide any clear status or instruction regarding the original prescription. Thus, "Void" is the correct and necessary term to guarantee proper handling and communication of the prescription’s new status after being transferred.
