Which of the following is NOT a requirement for a controlled prescription?

For a controlled prescription, there are several specific requirements outlined under both federal and Arkansas state law to ensure proper identification and accountability in the dispensing of controlled substances. The requirement that is not mandated pertains to the payment method, which is not a necessary aspect of the prescription itself.

Controlled prescriptions must include details such as the practitioner's full name along with their DEA registration number, which serves as verification of the authority to prescribe controlled substances. The patient's full name and address are also required to clearly identify who is receiving the medication, as well as to assist in tracking prescriptions and managing public health concerns. Additionally, the quantity prescribed is critical, as it indicates how much of the controlled substance is deemed appropriate for the patient's treatment.

Since the payment method is not included in the legal specifications for what constitutes a valid controlled prescription, it does not belong to the list of required components. Therefore, recognizing that C, or the method of payment, is not a necessary inclusion underscores a key aspect of understanding the regulations surrounding controlled substances.
