What might indicate an unstable compounded sterile preparation?

The indication that a compounded sterile preparation is unstable can be effectively assessed by observing for visible particulates, discolorations, or changes in consistency. These signs suggest that the integrity of the preparation has been compromised, potentially impacting its safety, efficacy, and overall quality.

Visible particulates may indicate contamination or degradation of the active ingredients, leading to concerns about potential adverse reactions when administered. Discoloration can signal a chemical change that may affect the potency of the preparation. Changes in consistency could suggest that the formulation has undergone physical changes, making it unsuitable for patient use. Each of these factors plays a crucial role in maintaining the sterility and effectiveness of compounded sterile preparations, which are critical in a clinical setting where patient safety is a priority.

In contrast, a sterile label merely indicates that the preparation has been made according to sterility standards at the time of compounding but does not provide insight into its stability over time. The absence of visible particulates or discoloration can be a positive sign; however, it does not guarantee the preparation's overall stability since some changes might not be visibly detectable. Meeting expiration dates is essential, but a product can still be unstable even if it is within the expiration period, necessitating vigilant assessment for signs of instability.
