Presentation Description

With the implementation of the new NAPRA sterile compounding guidelines across Canada, many pharmacies and pharmacy departments are faced with managing shorter beyond-use dates. This creates additional work, increases wastage, and can ultimately reduce patient access to certain compounded treatments. We’ll explore why these shorter beyond-use date limits were put in place and discuss strategies to overcome the challenge.
