What does the term 'beyond-use date' refer to?

The term 'beyond-use date' specifically refers to the last date a compounded sterile preparation (CSP) can be used or administered. This date is critical in ensuring patient safety, as it indicates the time beyond which the sterility and stability of the compounded preparation cannot be guaranteed. Beyond-use dates are established based on the risk level of the preparation, the storage conditions, and the type of ingredients used.

Understanding the significance of the beyond-use date is essential for healthcare professionals involved in the preparation and administration of sterile medications, as using a CSP beyond this date increases the risk of contamination or degradation, potentially leading to ineffective treatment or harm to patients.
