FDA Orange Book

The FDA Orange Book, officially called the Approved Drug Products with Therapeutic Equivalence Evaluations, is a reference guide that lists FDA-approved prescription drugs. It provides information about whether drugs are interchangeable, meaning a generic version can be substituted for the brand-name product without affecting safety or effectiveness. The book helps healthcare providers and pharmacies identify approved medications, understand their approval status, and determine bioequivalence, ensuring patients receive safe and effective treatment options.
