What action must a pharmacist take regarding quantity dispensed when partially filling an opioid?

When a pharmacist partially fills an opioid prescription, it is essential to make a note in the electronic health record. This documentation serves several important purposes. Firstly, it maintains an accurate and accessible record of the quantity dispensed, which is crucial for tracking the prescription's usage and ensuring compliance with regulatory requirements. Thirdly, having this information documented in the electronic health record supports continuity of care and helps to prevent potential medication errors or misuse, ensuring that both the pharmacist and other healthcare providers have a complete view of the patient's medication history.

Documentation in the electronic health record is a best practice that aligns with modern pharmacy operations and reinforces the importance of thorough and up-to-date patient records, particularly with controlled substances like opioids. This enables better patient management and adheres to regulations pertaining to the dispensing and handling of such medications.
