EQUIDONE (domperidone) Gel - Veterinarians

December 3, 2010

Dear Equine Veterinarian:

The U.S. Food and Drug Administration (FDA) recently approved EQUIDONE (domperidone) Gel for the prevention of fescue toxicosis in periparturient mares. At-risk mares are treated with EQUIDONE Gel once daily starting 10 to 15 days before their expected foaling dates. They may continue to be treated up to 5 days after foaling. Please see the approval announcement at

EQUIDONE Gel, distributed by Dechra Veterinary Products, is available in the United States as an oral gel. The gel comes in disposable 25 cc syringes that can be used for multiple doses. The strength is 110 mg domperidone per cc of gel. EQUIDONE Gel is the only FDA-approved animal drug that contains domperidone as the active ingredient. Now that EQUIDONE Gel is approved and available for veterinary use in the United States, domperidone should not be imported from other countries or compounded from bulk.

Each FDA-approved animal drug goes through a rigorous evaluation process. Before the drug is approved, it is clinically tested for safety and effectiveness in the target animal species. FDA also thoroughly inspects and evaluates the adequacy of the manufacturing process to make sure the drug’s identity, strength, quality, and purity are preserved. FDA continues to monitor the drug’s quality and safety after it is approved. An animal drug that is compounded from bulk drug ingredients is not FDA-approved. The safety and effectiveness of the compounded drug, as well as the adequacy of the manufacturing process, have not been evaluated.

In prescribing FDA-approved EQIDONE Gel to prevent reproductive problems associated with fescue toxicosis, you are providing your clients and their mares with the only domperidone product shown to be safe and effective in horses. Also, EQUIDONE Gel is the only domperidone product that is manufactured to meet FDA’s strict standards for quality, purity, and potency.

You may have specific patients that require domperidone in strengths or forms that are not offered by EQUIDONE Gel. In these limited cases, domperidone can only be legally compounded by using FDA-approved EQUIDONE Gel as the starting material. Additional requirements and information on legal animal drug compounding are available in Title 21, Code of Federal Regulations, Section 530.13.

At FDA’s Center for Veterinary Medicine (CVM), we are committed to promoting and protecting animal health by ensuring safe and effective drugs are available for animals.
