For parenteral administration. Dissolve the content of one sachet of Intromidium (1 g) in 50 ml or 100 ml of sterile water for injection to obtain a 2% (20 mg/ml) or a 1% (10 mg/ml) solution, respectively. Repeated injections are needed at intervals of 10 to 12 weeks or more, depending on the level of fly challenge.
Calves, goats and sheep : treatment : 0.25 - 0.5 mg/kg by deep IM injection.
prevention: 0.5 - 1 mg/kg by deep IM injection.
Camels : 0.5 - 0.75 mg/kg using a 1% solution by very slow IV injection.
Horses : 0.5 mg/kg by deep IM injection.
Dogs : 1 mg/kg by deep IM injection.
Deep IM injection should occur preferably in the middle third of the neck in large animals. Doses exceeding 10 ml should be injected at multiple injection sites on each side of the neck. Make sure that the syringe is completely empty before retracting it from the IM injection site. Afterwards, to prevent leakage of Intromidium into subcutaneous tissues, firm pressure must be applied on the injection site. Sheep and goats are injected deep in their thigh muscles.
