Under LOW RISK conditions, how long can preparations stored at controlled room temperature without sterility testing be stored?

• A. 48 hours
• B. 24 hours
• C. 72 hours
• D. 96 hours

Answer: (A)

Beyond-use dating for compounded sterile preparations depends on the risk level of the preparation and the storage condition. For a low-risk CSP stored at controlled room temperature, the time you can keep it without performing sterility testing is 48 hours. This reflects a balance: the low risk reduces contamination chances, but room temperature allows microorganisms to grow more quickly, so the window is limited. If you were to refrigerate, the valid window would be longer (around two weeks), and freezing could extend it even further. The other durations listed (24, 72, or 96 hours) exceed the recommended 48-hour limit for this scenario.
