About Authorized Generics

Choosing Winthrop US Authorized Generics ensures your patients get the same product they would from the brand name products of Sanofi.


The Truth Behind Authorized Generics

The term “authorized generic” drug is used to describe an approved brand name drug that is marketed without the brand name on its label. Other than the fact that it does not have the brand name on its label, it is the exact same drug product as the branded product.

Unlike some other generics, Winthrop US products use the same manufacturing process originally developed for the brand name. They are identical to Sanofi products in molecular weight distribution, quality control parameters, inactive ingredients and other key factors.
