Errata

Errata are published in the Pharmacopeial Forum and also posted here to assure that USP–NF users receive errata information in a timely manner. The errata are posted by the beginning of each month and are official as of their respective posted date.

USP has posted errata to the USP 33–NF 28 book and online versions to correct redesign errors that were discovered after publication of the book and prior to November 1, 2009. In addition, beginning December 1, 2009, USP will post errata on a monthly basis in order to more quickly correct errors identified in redesigned monographs appearing in USP 33–NF 28. These errata will be official May 1, 2010, in alignment with the official date of USP 33–NF 28.

For more information on the errata process, see USP's Guideline on the Use of Accelerated Processes for Revisions to USP–NF. Download the Guideline  (98KB).
