In compounding, what does BUD stand for and what does it define?

• A. Beyond-Use Dating
• B. Best Use Date
• C. Bio-Util Date
• D. Benevolent-Use Date

Answer: (A)

Beyond-Use Dating describes the period after a preparation is made during which it is considered safe and effective to use. It defines the exact date or time limit beyond which a compounded product should not be used, based on stability data, the formulation, and how it will be stored (such as at room temperature, refrigerated, or frozen). This is different from the expiration date on manufactured drugs or raw ingredients, which reflects their own shelf life under labeled conditions. When stability information is available, it can support a longer BUD within guidelines; if not, a conservative, shorter BUD is chosen to protect patient safety.
