Beyond-Use Dating

Meaning

Beyond-Use Dating, or BUD, represents the specific date and time after which a compounded pharmaceutical preparation should no longer be used, consumed, or stored. This date is assigned by the compounding pharmacist based on the preparation’s chemical stability, the risk of microbial contamination, and the nature of the ingredients. It is a critical quality control measure distinct from the expiration date of commercially manufactured drugs, ensuring the ongoing therapeutic integrity of personalized hormonal treatments.
