Which requirement is NOT needed when dispensing a C2 prescription?

The requirement regarding obtaining the patient's social security number is not needed when dispensing a prescription for a controlled substance classified as Schedule II (C2). While various patient identification details may be collected for different purposes, such as insurance verification or record-keeping, a social security number is not mandated by federal law or regulations for the dispensing of C2 prescriptions.

In contrast, signatures of the prescriber, the prescriber’s DEA number, and the date of the prescription are all essential components of a valid C2 prescription order. The prescriber’s signature ensures that the prescription is authorized, the DEA number confirms that the prescriber is legally permitted to prescribe controlled substances, and the date is crucial for maintaining accurate records and ensuring that the prescription is filled within the legal time frame. Therefore, these elements are necessary to comply with pharmacy law and ensure patient safety and regulatory compliance.
