USP 795 dating: a maximum dating for all water-containing preparations when stability unknown?

• A. True
• B. False
• C. Not specified
• D. It depends

Answer: (A)

The key idea is how USP <795> handles beyond-use dating (BUD) for compounded preparations that contain water when stability data are not available. Water-containing products are more prone to microbial growth and chemical changes, so without stability data to justify a longer shelf life, you protect patient safety by using a default maximum BUD of 14 days. This guideline helps ensure the product remains safe and effective during storage, typically under appropriate refrigerated conditions. If stability data exist, or if the formulation is nonaqueous or has proven longer stability with appropriate preservatives, longer dating can be justified. But when there is no stability information, the 14-day limit is the standard default.
