What critical information is needed when processing a transfer prescription?

When processing a transfer prescription, having the patient's name and the original prescription number is crucial. The patient's name ensures that the medication is accurately associated with the correct individual, preventing potential medication errors. The original prescription number serves as a unique identifier that links the prescription to the specific pharmacy from which it originated. This information allows the receiving pharmacy to retrieve the original details quickly, verify the prescription's validity, and ensure a smooth transfer of the patient's medication history.

While other options may include relevant details, they do not encompass the essential elements needed for a transfer. For instance, while the medication name is important, it alone does not provide the necessary context to link the transfer to the patient's records. Similarly, having the doctor's contact information and medication name or just the medication name and pharmacy location would not complete the necessary process for transferring a prescription accurately. Thus, focusing on both the patient's identity and the specific prescription details is key in ensuring patient safety and continuity of care.
