Which date applies to all Compounded Sterile Products (CSPs)?

• A. Expiration date
• B. Beyond use date
• C. Production date
• D. Quality assurance date

Answer: (B)

The Beyond Use Date (BUD) is the key date that applies to all Compounded Sterile Products (CSPs). This date is critical as it indicates the time frame within which the CSP is expected to maintain its required sterility and stability, ensuring that it is safe to use. The BUD is determined based on several factors, including the solvents used, storage conditions, and the specific type of compound being prepared. Properly adhering to the BUD helps prevent the potential degradation of the product or the growth of microorganisms, which can threaten patient safety.

In contrast, while an expiration date might apply to commercial products, it does not generalize to all CSPs. The production date simply marks when the CSP was made and is not a measure of its viability or safety. Quality assurance dates may be specific to internal processes of a facility and do not universally apply to CSPs themselves.
