Errata are considered to be text erroneously published in the USP–NF or its Supplements that does not accurately reflect the intended requirements as approved by the Council of Experts. Errata are posted here to ensure that USP–NF users receive Errata information in a timely manner. The Errata are posted on the last Friday of every other month and are official on the first day of the following month.
Errata are incorporated into the next available official publication as follows:
- Errata are corrected in each online publication (USP–NF annual edition, first and second Supplements) and include revision symbols to designate changes—
•new text• (ERR 1–Jul–2012).
- Errata are corrected in the annual print publication. Errata are corrected in print Supplements only when a title has been revised. Revision symbols are also included when Errata appear in print.
Errata are posted in a new interactive table below. Users can search for an item by title, or sort the table by column heading. In addition, data can be downloaded in CSV format and printed.
- Errata Official Date refers to the date the Erratum becomes official.
- Source Publication is the latest official publication where the Erratum appears, or upcoming official publication if the Erratum was introduced after the latest official publication.
- Page Number indicates where the item is found within the source print publication.
- Target Errata Print Publication specifies when the Erratum will be corrected in print and will always reflect the next available Book, as Errata corrections only appear in print supplements when a title has been revised.
- Target Online Fix Publication specifies when the Erratum will be corrected online and may be a Book or Supplement.
