    18.7mg/g Ivermectin

Administer orally as a single dose rate to horses at the recommended dose level of 0.2mg ivermectin per kilogram of bodyweight. Each syringe delivers 120mg ivermectin, sufficient to treat 600kg of bodyweight.

To ensure administration of a correct dose, body weight should be determined as accurately as possible.

If animals are to be treated collectively rather than individually, they should be grouped according to their bodyweight and dosed accordingly, in order to avoid under- or over-dosing.

This is a single dose product. Discard after use.

Dosing Instructions:

Each weight marking on the syringe plunger will deliver sufficient paste to treat 100kg bodyweight.

Unlock the knurled ring by making ¼ turn and slide the knurled ring up the plunger shaft so that the side nearest the barrel is at the prescribed weight marking. Turn the knurled ring ¼ turn to lock in place. Make sure the horse’s mouth contains no feed. Remove the plastic cap from the tip of the nozzle. Insert the syringe into the horse’s mouth at the interdental space. Advance the plunger as far as it will go, depositing the medication on the base of the tongue. Immediately raise the horse’s head for a few seconds after dosing.

The treatment schedule should be based on the local epidemiological situation.
