What must the receiving pharmacy notify the patient regarding the prescription from the previous pharmacy?

The correct choice highlights the necessity for clear communication between the receiving pharmacy and the patient regarding the status of their prescription when it is transferred from another pharmacy. When a prescription is transferred, the previous prescription effectively becomes void, as a new prescription record is created by the receiving pharmacy. This is crucial for ensuring that the patient's medication management is accurate and to avoid any potential confusion or misuse of old prescriptions that may not reflect the patient's current medication needs or any recent changes in therapy.

By informing the patient that the previous prescription is now void, it maintains transparency in the pharmaceutical process and helps to ensure patient safety. This allows the patient to understand that they should rely on the new prescription provided at the receiving pharmacy and not attempt to fill the earlier prescription, which may no longer be appropriate or valid.

The other options are not suitable as they do not comply with the established protocols of prescription transfers, which prioritize patient safety and accuracy. For instance, stating that the prescription is still valid could lead to misuse or confusion regarding which medication the patient should be using. Similarly, implying that nothing needs to be communicated or that the patient should contact the previous pharmacy does not uphold the responsibility of the receiving pharmacy to inform the patient of critical changes regarding their prescription status.
