Nonaqueous formulations prepared in a community pharmacy should be labeled with a Beyond-Use Date of no more than how long?

Beyond-use dates tell you how long a compounded preparation remains stable and safe to use. For nonaqueous formulations prepared in a community pharmacy, the maximum BUD is six months. This limit comes from stability data for water-free bases: microbial growth isn’t a big concern without water, but chemical stability and ingredient interactions still cap how long the product can be reliably used. When setting the date, you choose the earlier of six months from compounding or the earliest expiration date of any ingredient used. That’s why six months is the standard maximum.
