For Category 2 CSPs that are Aseptically Prepared with Passed sterility testing, what is the beyond-use date (BUD) at controlled room temperature?

For Category 2 CSPs that are Aseptically Prepared with Passed sterility testing, what is the beyond-use date (BUD) at controlled room temperature?

• A. 60 days
• B. 30 days
• C. 1 day
• D. 4 days

Answer: (B)

Understanding how sterility testing affects the beyond-use date for Category 2 CSPs When a compounded sterile product is prepared aseptically and then sterility testing is performed and passes, the product gains a longer, validated beyond-use date at the storage condition in question. For Category 2 CSPs stored at controlled room temperature, that approved BUD is 30 days. This reflects the added assurance from the sterility test, indicating the preparation remains sterile for a full month under typical room-temperature conditions (approximately 20–25°C). The other timeframes aren’t appropriate here: 1 day or 4 days would be too short given the sterility confirmation, and 60 days is not permitted at room temperature without additional stability data and specific validation.
