Revision Bulletins

Revision Bulletins are published in USP–NF Online by the first of each month. Each Revision Bulletin includes a notice that provides the reason for the change and the official date. Monograph names listed before April 1, 2021 contain a combined notice and documentary standard; postings after April 1, 2021 provide separate links for the notice and for the standard content. For more information on the Revision Bulletins and the Accelerated Revision process, see USP's Guideline on the Use of Accelerated Processes for Revisions to USP–NF and FCC. Archived Revision Bulletins can be found here.
