When transferring a prescription between two pharmacists, which method is allowed?

When transferring a prescription between two pharmacists, oral communication is the allowed method in Wisconsin. This is because direct oral communication between pharmacists allows for immediate verification and clarification of any details related to the prescription transfer.

Options B, C, and D are incorrect because in Wisconsin, faxing a prescription without further verification, using email without further verification, or leaving a written note for the receiving pharmacist are not considered appropriate methods for transferring prescriptions between pharmacists. These methods do not allow for real-time verification and may lead to miscommunication or errors in the transfer process.
