What is a precaution to take when prescribing a controlled substance?

Using tamper-proof paper for all prescriptions written for controlled drugs is a critical precaution because it helps prevent fraud and unauthorized alterations to prescriptions. Controlled substances are particularly susceptible to abuse and misuse, making it essential to implement measures that enhance the security of these prescriptions. Tamper-proof paper is designed to be more difficult to duplicate or alter, which can significantly reduce the risk of prescription fraud.

The other options do not provide the same level of protection against misuse. While standard prescription pads can be used for non-controlled substances, they are not secure enough for controlled drugs. Issuing prescriptions verbally increases the potential for misunderstandings and does not maintain a clear, secure record of the prescription, which can be concerning in terms of traceability and accountability. Allowing refills on a case-by-case basis does not directly address the security of the prescription itself and may lead to inappropriate use if not managed carefully. Thus, utilizing tamper-proof paper stands out as an essential practice when prescribing controlled substances.
