Errata

Errata, formerly published in the Pharmacopeial Forum (PF), are posted here to assure 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.

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