Board Certified Sterile Compounding Pharmacist (BCSCP) Practice Test

For water-containing topical and mucosal liquids, the BUD is not later than how many days?

Not later than 30 days Not later than 60 days Not later than 15 days Not later than 7 days

Correct Answer:

Not later than 30 days

Explanation:

Water-containing topical and mucosal liquids have water in the formulation, which allows microorganisms to grow if the product sits for too long. Because of that risk, the beyond-use date is limited to 30 days, providing a safe, practical window to use the product before microbial growth becomes a concern. Extending beyond 30 days would increase the chance of contamination or infection, while shorter time frames would unnecessarily shorten usable life without added safety benefits. For products without water, or for certain non-aqueous formulations, longer BUDs may apply, but for water-containing topical and mucosal liquids the standard is not later than 30 days.
