The following guidelines are provided to reduce the occurrence of inadvertent positives arising from the presence of prohibited substances within Out of Competition blood and urine specimens.

The trainer, assistant trainer or stable employee is responsible for accurately and legibly recording ALL preparations containing a prohibited substance (medication) and/or any veterinary treatment administered to any horse under their care in an approved Veterinary Treatment Register (VTR). The VTR must be kept up to date at all times.

As per Rule 10.5.14, the trainer may be guilty of an offence should the VTR entries be illegible, incomplete, or inaccurate.

Preparations (medications) which should be recorded:
All controlled substances (Schedule 7 & 8) administered by a veterinarian; all prescription only medicines (Schedule 3 to 6) prescribed and/or dispensed by a veterinarian including those used “extra-label”; all over the counter (OTC) medicines (Schedule 1 & 2) including topical ointments; all injectable veterinary medicines (all stock remedies including DMSO, vitamins and antibiotics) not already referred to above; all veterinary and other medicines containing other scheduled and unscheduled prohibited substances (all compounded medications including ammonium chloride); all alkalinising agents (bicarbonate of soda), commercial supplements, injectable salts, herbal or homeopathic preparations and all vaccinations registered for use in horses.

Veterinary treatments which should be recorded:
Extracorporeal shock wave therapy (ESWT); acupuncture (including laser treatment);
chiropractic treatment; the use of any electrical stimulation device (including transcutaneous electrical nerve stimulation (TENS)); magnetic field therapy; ultrasound; any form of oxygen therapy, including hyperbaric oxygen therapy and the taking of a blood sample.

The following details should be recorded:
  • date of administration
  • name of the prescribing veterinarian (if applicable)
  • name of the horse
  • name of the preparation (medication) or treatment administered
  • amount (dose) of medication given (if applicable)
  • route of administration (oral, topical, intravenous, intramuscular, subcutaneous or intraarticular)
  • duration of treatment (if a bottle or course of medication is prescribed and dispensed)
  • reason for administration (diagnosis e.g. lameness)
  • name and signature of the person/s administering the medication or treatment
All VTR entries should be made on the same day of administration or treatment. Therefore, the trainer MUST record the daily administration of medications which have been previously prescribed and dispensed by a veterinarian for several days to a month (such as Acepromazine or Furosemide).

When a horse is admitted to a veterinary hospital where the attending veterinarian does not have a VTR, the hospital discharge form and the account should be kept by the trainer in their VTR, as an approved treatment record.

Should a veterinarian use their “own VTR” to record treatments and/or veterinary procedures performed on a horse, it is the trainer’s responsibility to keep the yellow slip for their records and hand it over to the NHA when requested to do so. This is of particular importance during Out of Competition Specimen Collection where all treatment records relating to the horses selected will be requested by the licensed officials present.

The VTR should always be made available for inspection by any licensed official and once full, it should be returned to the NHA at which time, a new VTR will be issued. A VTR can be collected by the NHA at any time, and then a new one issued. The trainer shall be guilty of an offence in terms of the Rules if they fail to keep a completed VTR up to date (same day updated), in the manner prescribed or to make it available for inspection when requested to do so.


As per legislation and the Rules of the NHA, all Schedule 3 medication and higher as well as all compounded medication, MUST be prescribed by a veterinarian and appropriately labelled. This includes personal medications kept at stable yards which have been prescribed by a medical health practitioner and dispensed by a pharmacist.
Notwithstanding the manufacturers’ label, a further label should be applied indicating the following:
  • name or the name of each active ingredient of the medicine
  • name of the owner/trainer to whom such medicine is supplied to (sold to)
  • name of the horse to which such medicine is to be administered
  • directions for the use of such medicine (dose, route, and frequency of administration)
  • name and business address of the dispensing veterinarian or pharmacist
  • date of dispensing
  • Veterinary Treatment Register (VTR) page number
Note: It is illegal for any person to use expired medicines for treatment under any conditions (even for welfare cases). All expired medication should be immediately removed from the stable yard and returned to the dispensing veterinarian or pharmacy where it was obtained for safe disposal.
