What is the approved beyond-use time (BUD) for immediate use compounds?

• A. 30 minutes
• B. 1 hour
• C. 4 hours
• D. 24 hours

Answer: (B)

Immediate-use compounds are sterile preparations made for urgent use when a full sterile compounding area isn’t used. Because they’re prepared outside a controlled environment, the safety window is kept very short. The approved beyond-use time is one hour from the start of preparation, and the product must be used within that hour for the specific patient. If it isn’t used in that window, it should be discarded and not stored or reused. This tight 1-hour limit reflects the higher risk of contamination with immediate-use preparations. Other time frames don’t fit this scenario because 30 minutes is not the standard BUD for immediate use, and 4 hours or 24 hours are associated with longer storage in other categories of compounded sterile products, not immediate-use items.
