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.
Dosing Instructions
To ensure administration of a correct dose, body weight should be determined
as accurately as possible; accuracy of the dosing device should be checked.
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.
Parasite control program:
Veterinary advice should be given on appropriate dosing programs and stock
management to achieve adequate parasite control.

This product has been formulated specifically for use in horses only. Dogs and
cats may be adversely affected by the concentration of ivermectin in this
product if they are allowed to ingest spilled paste or have access to used
syringes.

Some horses carrying heavy infection of Onchocerca microfilariae have
experienced oedema and pruritus following dosing, assumed to be the result of
death of large numbers of microfilariae. These signs resolve within a few days
but symptomatic treatment may be advisable.

Care should be taken to avoid the following practices because they increase the
risk of development of resistance and could ultimately result in ineffective
therapy:
- Too frequent and repeated use of anthelmintics from the same class,
over an extended period of time.
- Underdosing, which may be due to underestimation of body weight,
misadministration of the product, or lack of calibration of the dosing
device.
Suspected clinical cases of resistance to anthelmintics should be further
investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test).
Where the results of the test (s) strongly suggest resistance to a particular
anthelmintic, an anthelmintic belonging to another pharmacological class and
having a different mode of action should be used.
Resistance to macrocyclic lactones (which includes ivermectin) has been
reported in Parascaris equorum in horses in a number of countries within the
EU. Therefore, the use of this product should be based on local (regional, farm)
epidemiological information about susceptibility of gastro-intestinal nematodes
and recommendations on how to limit further selection for resistance to
anthelmintics.

No special precautions are required.
Special precautions to be taken by the person administering the product
to animals
Do not smoke, drink or eat while handling the product.
Wash hands after use. This product may cause skin and eye irritation.
Therefore, the user should avoid contact of the product with the skin and the
eyes. In the case of contact, rinse immediately with plenty of water.
In the case of accidental ingestion or eye irritation after contact seek medical
advice immediately and show the package leaflet or the label to the physician.
