FDA has republished a 3/2021 guidance, *Covid-19 Container Closure System and Component Changes: Glass Vials and Stoppers*, with a note that the [document](https://www.fda.gov/media/167925/download?ref=fdaweb.com) is intended to remain in effect until 8/7/2024 unless superseded by a revised final guidance before that date. The guidance collated recommendations for appropriate reporting category and the content of postapproval change submissions across numerous agency guidances. It has recommendations for holders of approved NDAs, BLAs, and ANDAs about the reporting and implementation of some common changes to container closure system components consisting of glass vials and stoppers for approved sterile drug products administered parenterally.
