For Category 3 CSPs that are Terminally sterilized + Sterility tested + Passed all applicable tests for Category 3 CSPs, what is the BUD at room temperature?

For Category 3 CSPs that are Terminally sterilized + Sterility tested + Passed all applicable tests for Category 3 CSPs, what is the BUD at room temperature?

• A. 120 days
• B. 60 days
• C. 180 days
• D. 90 days

Answer: (D)

The main idea is how beyond-use dating is set based on sterility assurance. If a Category 3 CSP has been terminally sterilized and then sterility tested—with all applicable tests passed—it has the strongest sterility guarantee among these products. That combination justifies extending the room-temperature BUD to 90 days. Terminal sterilization destroys any microorganisms in the final product, and sterility testing (when it shows no contamination) provides confidence that the product remains sterile through its stated storage period. Because of this validated sterility, a 90-day shelf life at room temperature is appropriate. If these validations weren’t complete or the tests hadn’t all passed, the BUD would be shorter, which is why the other durations aren’t applicable here.
