NSF/ANSI 455-4: OTCs (Over-the-Counter Drugs)

To meet a growing concern over the quality of OTC drugs, NSF facilitated the development of an NSF/ANSI 455 GMP audit standard specifically for OTC products.
GMP Certified NSF/ANSI 455-4 OTC Drugs

We are currently accepting applications for audits for OTC drugs (NSF/ANSI 455-4), and the current GMP registration for OTCs will be phased out entirely by 2022.

To help you understand this new international Good Manufacturing Practice (GMP) standard, NSF has developed resources to simplify your certification process.
