Confusion as to what liniments can be used in USEF Rated shows have brought the organization to release this press announcement:
The classification of these substances as Forbidden is neither a new policy nor a recent development. Some of the ingredients in the above listed liniments have been Forbidden substances for more than 20 years. These substances, and products containing them, are classified as Forbidden because of their potential actions on various body systems when administered intravenously, intramuscularly, subcutaneously, or orally.
However, when used topically and as recommended by their manufacturers, these products have not been associated with a positive by the Federation. As a practical matter, provided the products containing these substances are administered only topically and as recommended by the manufacturer, there is no need for restricting their use during competitions under USEF rules. However, if these substances are used inappropriately e.g., in a manner other than topically, this could result in a positive finding in the blood or urine of the horse, which would be a potential violation of the rules.
One exception is the substance capsaicin and closely related analogues (ex. Capsicum Oleoresin as found in Equi-Block®.) There were four drug violations associated with the detection of capsaicin in the blood following topical administration at the 2008 Olympic Games. Neither of these substances or other capsaicin derivatives should be used topically in any poultice or liniment within the 7 days preceding competition. It is important to note that many preparations produced for the equine market routinely have their formulations changed without any published notice. It is for this reason that the USEF Equine Drugs and Medications Program typically does not comment on products by name, but requests lists of ingredients. It would be irresponsible for the USEF to list name brand products as Forbidden or Permitted as there is no control or notification of changes in their ingredients.
