What is electronic prescribing (eRx)?

Electronic prescribing, often referred to as eRx, is defined as the process of sending prescriptions electronically to pharmacies. This method leverages digital technology to facilitate the transmission of prescription information directly from the prescriber’s electronic health record (EHR) system to the pharmacy, eliminating the need for paper prescriptions.

This process enhances efficiency, reduces the possibility of prescription errors associated with handwritten instructions, and allows for real-time access to medication management. Furthermore, eRx systems can integrate features such as checking a patient’s medication history and allergies, which supports safer prescribing practices.

The other options describe outdated or less efficient methods of managing prescriptions, such as using paper prescriptions or faxing them, which do not offer the same level of convenience, accuracy, and accountability that electronic prescribing does. Therefore, understanding eRx is crucial for optimizing prescription workflows and improving patient care in modern healthcare environments.
