Guidance & Regulations

Laws, Regulations, and Guidances; FDA's Center for Veterinary Medicine


The Food, Drug, and Cosmetic Act (FD&C Act) gives FDA and its centers, including the Center for Veterinary Medicine (CVM), their legal authority.  The FD&C Act has been amended over the years by other acts that specifically address CVM’s authority, including: 

Laws Relevant to FDA/CVM


FDA issues regulations to implement laws for state and local governments, industry, other organizations, and the general public.  Though they are not laws, regulations have the weight of law.  FDA follows the procedures required by the Administrative Procedure Act when issuing regulations. FDA regulations can be found in Title 21 of the Code of Federal Regulations (CFR).  

FDA Regulations

Guidance Documents

Guidances describe FDA’s current thinking on a topic.  These documents provide additional detail or perspective on matters described in laws and/or regulations, thereby giving stakeholders a better understanding of the Agency’s expectations.  Guidance is not legally binding on the public or the Agency.  

  • Compliance Policy Guides (CPGs) are guidance documents that provide guidance to the field offices regarding compliance policy and other regulatory action.
  • FDA follows the procedures required by its "Good Guidance Practices" regulation to issue FDA guidance.

MOU are intended to improve consumer protection through more effective use of collective resources and to eliminate duplication of activities.
