Product Description

The product is indicated for use as an anti-inflammatory and anti-allergic agent in horses, cattle, dogs and cats, and for the treatment of primary ketosis in cattle.

The product can also be used to induce parturition in cattle. 


Dosage & Administration

Shake vial before use. Dexafort should be administered by intramuscular injection.

For the treatment of inflammatory or allergic conditions the following average doses are advised. However the advised dose used should be determined by the severity of the signs and the length of time for which they have been present.

Horses, cattle - 1 ml/50 kg

Dog, cat - 0.5 ml/10 kg  

For the treatment of primary ketosis in cattle (acetonaemia)

A dose of 5-10 ml dependent on the size of the cow.

  • Since blood sugar levels rise rapidly following injection of the product, through the action of dexamethasone sodium phosphate and raised levels are maintained for several days, the product is particularly useful in cases that present late and there is seldom a need to repeat the dose.
  • In the case of cows in poor bodily condition, to avoid prolonged stimulation of gluconeogenesis at the expense of body fat reserves, use a product containing only the quick-acting ester.

For the induction of parturition

  • The product may be used to induce parturition in cattle in the last trimester and before day 260 of pregnancy.
  • Where this is required e.g. in the cases of trauma to the cow or possibly because the date of calving is not known a single dose of 10 ml followed 6-12 days later by an injection of a short acting corticosteroid such as dexamethasone sodium phosphate alone is recommended.
  • In the majority of cases parturition will be induced within 3 days of the second injection. 




  • Meat - 63 days
  • Milk - 144 hours


  • Not to be used in horses intended for human consumption.
  • Treated horses may never be slaughtered for human consumption.
  • The horse must have been declared as not intended for human consumption under national horse passport legislation.
