AMA Style: The Basics for Pharmacy Writing: USP-NF

The USP-NF is a two-book compilation (the United States Pharmacopeia and the National Formulary) of 4 volumes and AMA doesn’t provide an example for this in the Manual of Style, so we must improvise!

Note:  In order to access the USP-NF online, you must create a free Access Point account with your UWaterloo email address.  Instructions can be found on this page.

Title. Title of specific monograph or chapter.  In: USP-NF Online. Place of publication: Publisher. Updated date. Accessed date. URL to the monograph or chapter (No period after the URL)
