The 2019 USEF Annual Meeting Registration is now open.


The Equine Drugs and Medications Program has worked to protect the welfare of equine athletes and ensure the balance of competition for nearly 50 years. The program utilizes veterinarians and technicians around the country to collect blood and urine samples from horses competing at USEF events. What makes the Equine Drugs and Medications Program truly unique is the comprehensive nature of our program in maintaining all three important components necessary for successful drug testing: the collection of samples, the analysis of samples, and ongoing research to stay current in the enforcement of medication rules.

Initially, the program was dependent upon an outside laboratory to analyze the random samples collected at competitions across the country. In 1995, the Equine Drug Testing and Research Laboratory (EDTRL) was established by the Equine Drugs and Medications Program and currently conducts all sample analysis for USEF. Additionally, the EDTRL is only one of five laboratories worldwide that is an FEI Reference Laboratory, and the only one in the western hemisphere.

The USEF strongly encourages its members to review the current Drugs and Medications Rule and to be aware of the published recommendations for treating a horse in competition. These recommendations can be found in the Federation’s Drugs and Medications Guidelines pamphlet and are provided as a link on this website. If you have questions not answered in the pamphlet please contact the Equine Drugs and Medications Program.

AAEP Clinical Guidelines for Veterinarians Treating the Non-Racing Performance Horse

The AAEP recommends these “Clinical Guidelines for the Treatment of Non-Racing Performance Horses” to enable its members and the equine industry to provide appropriate care of the horses involved. While veterinary practices may vary depending upon the type of competition, basic tenets concerning diagnosis, treatment and safe and ethical use of medications must be employed. Treatment of equine athletes must be directed toward normalizing their performance and avoiding performance enhancement by illegal or unethical means. While veterinarians are required to follow the regulations governing the discipline in which their patients are competing, participation in the establishment of these rules and regulations can be the most effective way to ensure that they are reasonable, uniform and give due consideration to the health and welfare of the horse.
