What is the Beyond Use Date for water-containing topical/dermal and mucosal formulations?

The correct answer for the Beyond Use Date (BUD) for water-containing topical/dermal and mucosal formulations is 30 days. This guideline is established to ensure that these formulations are safe and effective for use, as the presence of water can promote microbial growth, which may decrease the efficacy of the product or lead to potential contamination.

Water-containing formulations are more susceptible to stability issues compared to those without water because they provide a medium for bacteria and fungi. Therefore, a BUD of 30 days is considered appropriate, balancing the need for the product to remain safe while allowing for use within a reasonable timeframe.

Understanding the importance of BUD helps pharmacy technicians ensure patient safety and the effectiveness of compounded medications, especially in cases where the composition includes ingredients that could be unstable or risk contamination over time.
