The USP–NF is a combination of two compendia, the United States Pharmacopeia (USP) and the National Formulary (NF). It contains standards for medicines, dosage forms, drug substances, excipients, biologics, compounded preparations, medical devices, dietary supplements, and other therapeutics. The current version of USP–NF standards deemed official by USP are enforceable by the U.S. Food and Drug Administration for medicines manufactured and marketed in the United States. Learn more about the USP–NF and how it is developed.

A new edition with 2016 standards—USP 40–NF 35—becomes official August 1, 2017

An official Spanish edition is available in print.
