Equivac® TAT is 1500IU/mL tetanus antitoxin that is prepared by immunising horses against the toxin produced by Clostridium tetani and then refining the serum to produce the antitoxin.

Approved Uses

Equivac® TAT is used in the prevention and treatment of tetanus in horses and can also be used in dogs, sheep, cattle and pigs. The minimum required dose should protect the animal if it is administered within hours of an injury occurring. For prolonged protection, however, a horse should be actively immunised using Equivac® T or Equivac® 2 in 1 on a regular basis.

Indication Short term protection against and treatment of tetanus in horses, cattle, sheep, goats, pigs and dogs. See product literature for further details.It is recommended that horses be actively immunised for permanent protection whenever and wherever there is a risk of tetanus. This may be achieved by using Equivac T (tetanus toxoid) or Equivac 2 in 1.
Actions The injection of a relatively small dose of antitoxin, such as the minimal doses recommended for prevention, if given within a few hours of the injury, should provide effective protection over the usual danger period. The period of protection will be prolonged with increased dosage of antitoxin.
Precautions Sterilise all injection apparatus by boiling before use. Maintain cleanliness at all times. Keep needles sharp and clean; replace frequently. Use needles of appropriate gauge and length. Avoid injection of animals during wet weather or under dusty conditions as far as possible. Make injections on the middle of the neck.Take care to avoid accidental self-injection.First Aid If poisoning occurs, contact a doctor or Poisons Information Centre. Phone Australia 131 126.
Dosage and Administration Before the antitoxin is injected, the proposed site of inoculation on the animal's skin may be cleaned by swabbing with cotton wool soaked in a suitable antiseptic solution, such as methylated spirits.Tetanus prevention. The injection is given subcutaneously. Horses, foals. Not less than 1500 U. The most convenient site in horses for injection is the centre of the side of the neck. Adult cattle. Not less than 1500 U. Calves. Not less than 500 U. Sheep. Not less than 500 U. Lambs. Not less than 100 U. Goats. Not less than 500 U. Pigs. Not less than 500 U. Piglets. Not less than 100 U. Dogs. Not less than 250 U.Lambs and piglets receiving 100 U at marking will be protected during the ensuing danger period.Combined active-passive immunisation. Simultaneous injection of Equivac TAT and Equivac T results in both immediate and lasting protection. Inject Equivac TAT on one side of the body and Equivac T on the other using a separate syringe and needle for each. Repeat the dose of Equivac T four weeks later. If the dose of Equivac TAT given is as recommended above, there will be no interference with the development of active immunity.Tetanus treatment. Antitoxin is less effective in the treatment of tetanus than it is in prevention. It must be emphasised that treatment is more likely to be successful if the antitoxin is administered early in the course of the disease. The suggested minimum therapeutic dose for horses and foals is 10,000 to 20,000 units. Give the antitoxin for treatment slowly by the intravenous route.
