here are times where you will be provided with BUD dates. When you do not have access to the BUD dates, you will have to determine that date yourself. What is the appropriate BUD date for a water containing oral formulation? Not later than 14 days Not later than 30 days

Beyond Use Date (BUD) is the date after which a compounded sterile preparation may not be stored or transported. This time is calculated from the date of compounding, and it is different from expiration date. This is because the BUDs are assigned with a different approach from those applied to assigning expiration dates to manufactured drug products. Also, compounded preparations are intended for administration following short-term storage. So, the BUD is the date after which a compounded preparation shall not be used. A reliable BUD is established to ensure that the preparation has an accepted quality and purity at least until the labeled BUD.

BUD is calculated by:

Type of container in which it is packaged
How long the medication will be taken
Type of drug
How fast is the drug degradated
Storage conditions
Dosage of the medication
Nature of the drug and its degradation mechanism
Potential for microbial proliferation in the preparation

For Nonaqueous Formulation, the BUD is not later than 6 months or the time remaining until the earliest expiration date of any API (Active pharmaceutical ingredient), whichever is earlier.

For Water-Containing Oral Formulation, the BUD is not later than 14 days when it is stored at controlled cold temperatures.

For Dermal and Mucosal Liquid, Semisolid Formulations/Water-Containing Topical, the BUD is not later than 30 days.
