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 at the end of each 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 the USP-NF online publication on the same date as the errata table is published. Revision symbols will designate changes: —▲new text▲ (ERR 1–Jul–2018).
  • All Errata are corrected in the next available main print edition.

Errata are posted in the interactive table below. Entries are searchable by title, and each column heading can be sorted. In addition, table entries 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.
  • Errata Post Date specifies when the Erratum first appeared in the online errata table.
  • Target Errata Print Publication specifies when the Erratum will be corrected in a print publication.
