Current Animal Drug Shortages

(Medically Necessary Veterinary Products)


When drug shortages involve medically necessary veterinary products, it is FDA’s policy to help prevent or alleviate them. FDA works with drug manufacturers in the U.S. and, when necessary, other countries, to find ways to resolve these shortages. FDA does not have the authority to require a company to make any product, even if it is medically necessary.

A Medically Necessary Veterinary Product (MNVP) is a product that: (1) is used to treat or prevent a serious animal disease or condition or is needed to ensure the availability of safe food products of animal origin, and (2) no other available source of that product or adequate alternative drug substitute exists. Owner inconvenience and non-therapeutic uses are inappropriate reasons for classifying a product as an MNVP.
