Medication Rules

Complying with the medication rules can be a complex and, at times, stressful process for competitors as well as Veterinarians. In the following sections there is information on the rules for USEF sanctioned events which are less restrictive than for those entering in FEI sanctioned events.

USEF Rules - Medications

The following is a summary of the information from the 2012 medication rules issued by the USEF and is meant to provide guidance prior to competitions. Medication Information for USEF Competitions (PDF ~ 59.38Kb)

FEI Rules - Influenza Vaccination

Equine Influenza

Please see the summary provided below regarding Equine Influenza Vaccination requirements; full details can be found in the latest version of the FEI Veterinary Regulations.

Since 1 January 2005, all horses competing in FEI competitions require an influenza vaccination within six months + 21 days of the competition (No Flu vaccine to be administered within 21 days of an FEI competition).

  1. All horses intending to participate in FEI competition must have at least received:
  • a primary course of two vaccinations, given between 21 and 92 days apart
  • a third dose (the first booster) must be given within 6 months and 21 days after the date of administration of the second primary dose.
  • at least annual boosters given subsequently (i.e. within 365 days of the last dose)

2. If the horse is scheduled to take part in an FEI competition, the last booster must have been given within 6 calendar months + 21 days of arrival at the FEI event. (The 21-day window has been provided to enable vaccination requirements to fit in with the competition schedule.)

  1. No vaccination within 7 days of arrival at the FEI event

NOTE: any horses certified as correctly vaccinated under the FEI equine influenza vaccination rule prior to 1 January 2005 are not required to start a primary course again, provided they have complied with the previous primary course requirements and annual re-vaccinations. The requirement for a booster vaccination within 6 calendar months + 21 days of the day of arrival at the FEI event is effective.

AQHA Rules - Medications

The medication rules regarding the NSAID list, use of steroids and Robaxin (Methocarbamol )from the USEF rules are identicall. The exceptions are the four medications listed below:

Acetazolamide

May only be administered to horses documented through DNA testing to be positive (N/H or H/H) for HYPP (Hyperkalemic Periodic Paralysis). While these rules do not contain a maximum allowable plasma concentration level for Acetazolamide, laboratory detection of levels of Acetazolamide that are not consistent with administration in accordance with the following Guidelines may result in prosecution of a rule violation.

Guidelines: When acetazolamide is administered, the dose should be accurately calculated according to the actual weight of the animal. Each 24 hours, not more than 3 milligrams per pound of body weight should be administered. For a 1000 pound animal, the maximum daily dose is 3 grams.

Lasix - Furosemide

When used must be administered intravenously at least four hours prior to competition.

Isoxsuprine

Guidelines: When administered, the dose should be accurately calculated according to the actual weight of the animal. Each 24 hours, not more than 1.6 milligrams per pound of body weight should be administered (usually divided in two equal doses given 12 hours apart). For a 1,000 pound animal, the maximum daily dose is 1,600 milligrams, which equals 80 20-milligram tablets. No part of a dose should be administered during the four hours prior to competing. Any medicated feed should be consumed and/or removed at least four hours prior to competing.

Local Anesthetics - Lidocaine or Mepivicaine

May only be used under actual observation of event management (or designated representative) and/or the official show veterinarian, either of which must sign the medication report form, to aid in the surgical repair of minor skin lacerations which, by their very nature, would not prevent the horse from competing following surgery. Medication report form must be filed with show management as required in section 2 above.
