The Food and Drug Administration has issued Guidance Document #233 (GFI #233) to describe a suggested common format for VFD forms. Drug sponsors are required to provide a VFD form to FDA as part of the VFD drug approval process and make this form available for veterinary use following approval. Veterinarians, however, are not required to use the form provided by the drug sponsor and may create a form of their choosing as long as it contains the required information. GFI #233 also provides guidance concerning the elements that must be included on the VFD and the elements that may be included on the VFD. In addition, GFI #233 provides examples of a suggested VFD format.
