Understand the New Format for Drug Expiration Dates
You'll see a standard format for manufacturer's drug expiration dates...due to USP Chapter <7> med labeling standard revisions.
It's been a long time coming. For years, there's been confusion due to ambiguous month abbreviations...nonuniform order format of day, month, and year...and other quirks.
For example, the abbreviation "JN" could be read as January or June...and "MA" as March or May. Or a date printed as "19-10-21" could be read as October 19, 2021 or October 21, 2019.
