The expiration regulation for compounded aqueous solutions is that they are typically assigned a maximum expiration date of 14 days when stored at room temperature. This guideline is based on the stability of aqueous solutions that can promote microbial growth and chemical degradation if left at room temperature for extended periods.

Aqueous solutions, which contain water as a solvent, are susceptible to contamination and instability. The 14-day expiration helps mitigate risks associated with these factors, ensuring patient safety and maintaining the integrity of the medication.

The other options do not align with standard compounding guidelines for aqueous solutions. For instance, while some compounded products may indeed last longer than 14 days under specific conditions, and some may align with commercial products, the universally accepted maximum for room temperature storage of aqueous solutions is 14 days.
