Why is it necessary to perform an override pull for a medication that hasn't been verified by the pharmacy?

Performing an override pull for a medication that hasn't been verified by the pharmacy is necessary because unverified medications don’t appear on the patient profile in the automated dispensing system. This absence from the patient profile suggests that the medication has not undergone the necessary verification process to ensure its accuracy, appropriateness, and safety for a specific patient. Therefore, to maintain patient safety and ensure proper medication administration, the override pull allows for immediate access to needed medications, although it emphasizes the importance of subsequent verification by pharmacy staff to confirm that the medication is suitable for the patient.

The other options do not accurately represent the key purpose of the override pull or the implications of unverified medications. For instance, while dosage discrepancies may arise, unverified medications are not specifically linked to lacking a dosage. Similarly, the risk of expiration isn't universally applicable to unverified medications, nor do they inherently carry a higher risk of side effects solely based on their verification status. The primary concern remains their visibility within the patient's profile in the dispensing system.
