For immediate use compounded sterile preparations (CSP), how quickly must they be administered?

The requirement for immediate use compounded sterile preparations (CSP) dictates that these preparations must be administered within 1 hour of their preparation. This regulation is in place to minimize the risk of contamination and ensure patient safety, as the longer a sterile preparation is held before administration, the greater the potential for microbial growth and degradation of the compounded product.

Immediate use CSPs are specifically intended for situations where the patient needs the medication right away and do not have time for a more extensive preparation process. These preparations are generally created in an emergency setting or for procedures that require immediate medication delivery. Hence, the 1-hour time frame is set as a safeguard to ensure that the sterile integrity of the preparation is upheld during this window, thereby reducing the chances of infection and ensuring the efficacy of the treatment administered.

Other options reflect longer time frames than what is deemed acceptable for immediate use, as any delay beyond 1 hour could compromise the safety and efficacy of the compounded sterile preparation, making them unsuitable for patient use.
