If a pharmacist is unable to supply the remainder of a partially filled CII prescription within the required time, what must they do?

When a pharmacist is unable to supply the remainder of a partially filled CII prescription within the required timeframe, notifying the prescriber and informing the patient is crucial. This action ensures that the prescriber is aware of the situation and can decide whether to adjust the treatment plan or issue a new prescription if necessary. Additionally, informing the patient maintains transparency and keeps them in the loop about their medication, which is important for patient care and safety.

The requirement to notify the prescriber aligns with regulatory expectations, emphasizing the collaborative role of pharmacists in patient care. Furthermore, notifying the patient allows them to understand why they might not receive their medication in full, which can help in managing their expectations and any potential need for interim solutions for their health management.

Other potential actions, such as dispensing a different medication or immediately reissuing the prescription, do not comply with the regulations surrounding controlled substances, particularly the specific protocols for CII medications. These steps could lead to legal complications or issues with patient safety and care continuity.
