What is a requirement for an electronic prescription?

An electronic prescription must be dated and signed using an electronic signature on the day it is issued. This requirement ensures that the prescription is authentic and represents the prescriber's intent at that specific point in time. The use of an electronic signature not only maintains the security and integrity of the prescription but also facilitates the electronic transmission of the prescription to pharmacies, which is a critical aspect of modern medication management. This approach helps streamline the filling process, reduces errors from handwriting, and promotes efficiency in the healthcare delivery system.

In contrast, the other options do not align with the regulatory framework for electronic prescriptions. For instance, printing and signing a prescription contradicts the very nature of an electronic prescription, while requirements regarding timeframes and witness signatures are not applicable in the context of electronic prescriptions as defined by current standards.
