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.
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.
For the prevention of tetanus, in horse and foals, no less than 1500IU (1mL) should be given. Give subcutaneously after clipping the hair and disinfecting the skin.
Store at 2°-8°C (refrigerate)
