Revision Bulletins

Revision Bulletins are posted by the first of each month. Each Revision Bulletin includes the reason for the change, the complete Monograph or General Chapter, and the official publication in which the Revision Bulletin will be incorporated. Revision Bulletins are transferred to the Accelerated Revision History section when the standard is published and becomes official in the next USP–NF book or Supplement. 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. See the chart below for specific posting and official dates.
