Dose to be administered and administration route
Dosage:
One syringe division of paste per 100 kg body weight (based on a recommended dosage of 200 μg ivermectin per kg body weight).
The syringe containing 6.42 g of paste delivers sufficient paste to treat 600 kg of bodyweight at the recommended dose rate.
The syringe containing 7.49 g of paste delivers sufficient paste to treat 700 kg of bodyweight at the recommended dose rate.
Administration:
The paste is given by oral route.
To ensure administration of a correct dose, body weight should be determined as accurately as possible. The animal’s mouth should be free from food to ensure swallowing. Turn the screw gauge on the syringe plunger to the body weight of the horse. The tip of the syringe barrel should be inserted at the interdental space (the gap between the front and back teeth) and the paste deposited on the base of the tongue. Advance the plunger as far as it will go, depositing the medication on the base of the tongue. Immediately elevate the horse’s head for a few seconds to ensure swallowing.
