About the Orange Book

The Orange Book is 35 Years Old!

The publication Approved Drug Products with Therapeutic Equivalence Evaluations (the List, commonly known as the Orange Book) identifies drug products approved on the basis of safety and effectiveness by the Food and Drug Administration (FDA) under the Federal Food, Drug, and Cosmetic Act (the Act). (For more information, see the Orange Book Preface.)

The Approved Drug Products list first appeared as a print publication in October 1980. With the 25th edition (2005), Portable Document Format (PDF) versions of the Annual Edition and the Cumulative Supplement became available.

The Orange Book Search was added to the FDA website October 31, 1997.
