What must appear on a prescription for controlled substances according to Kentucky law?

In Kentucky, the law mandates that a prescription for controlled substances must contain only one prescription per blank. This regulation is in place to ensure clarity and prevent confusion regarding the medication being prescribed. Having a single prescription on one blank simplifies the process for both the prescribing physician and the pharmacist, reducing the risk of errors and ensuring compliance with state and federal regulations regarding controlled substances.

The requirement for one prescription per blank supports proper record-keeping as well. It aligns with best practices in pharmacy to facilitate accurate dispensing and tracking of controlled substances, which are subject to stricter regulations due to their potential for abuse and dependence.

The other options, such as the idea of having two prescriptions on one blank, contradict this guideline and would create ambiguity in dispensing. A watermark indicating security may be a feature of official prescription pads to prevent fraud but is not specifically mandated to be present on every prescription for controlled substances. Similarly, while an expiration date can be important, it is not a specific requirement in Kentucky law for the prescription itself. Thus, the emphasis on having only one prescription per blank stands as the critical requirement under Kentucky law for prescriptions for controlled substances.
