How many times may C3-C5 prescriptions be transferred?

The correct answer is that C3-C5 prescriptions may be transferred only once. This is rooted in federal regulations regarding the transfer of controlled substances. Specifically, for Schedule III, IV, and V drugs, the law permits a one-time transfer between pharmacies unless the pharmacies share a real-time online database, in which case they may transfer prescription information as needed.

The rationale behind the one-time transfer rule is to discourage multiple transfers that can potentially lead to misuse or diversion of controlled substances. This regulation aims to enhance security and tracking while maintaining a balance between accessibility for patients and safety measures to prevent abuse of these medications.

Other options suggest a higher number of transfers, which does not align with the constraints set forth by federal law on the transfer of controlled substance prescriptions. The allowance for a single transfer serves as an important guideline within the context of pharmacy practice and management of controlled substances.
