The product has been formulated for use in horses and donkeys 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.

Special warnings for each target species

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 gastrointestinal nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Special precautions for use in animals;

No special precautions are required.

Special precautions to be taken by the person administering the product;

Do not smoke, eat or drink 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 insert or the label to the physician.

Adverse reactions;

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.

Use during pregnancy, lactation or lay;

Horses and donkeys of all ages, including pregnant mares and breeding stallions, have been treated with no adverse effect.


The product has been used in conjunction with other equine health care products and no interactions have been identified.

Parasite control program; All horses and donkeys should be included in a regular parasite control program, with particular attention being paid to mares, foals and yearlings. Foals should be treated initially at 6 to 8 weeks of age, and routine treatment repeated as appropriate.

The product is highly effective against gastrointestinal, cutaneous and pulmonary nematodes and bots of horses. Regular treatment will reduce the chances of verminous arteritis and colic caused by Strongylus vulgaris. With its broad spectrum, the product is well suited to be the major medication in parasite control programs and the major component in a rotational program.


Mild transitory signs (slowed pupillary light response and depression) have been seen at a dose of 1.8 mg/kg (9 times the recommended dose level). Other signs seen at higher doses include mydriasis, ataxia, tremors, stupor, coma and death. The less severe signs have been transitory. No antidote has been identified; however, symptomatic therapy may be beneficial.

Amounts to be administered and administration route

Administer orally to both horses and donkeys at the recommended dose level of 0.2 mg ivermectin per kilogram of bodyweight. Each syringe delivers 120 mg ivermectin, sufficient to treat 600 kg of bodyweight.

To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked.

Dosing instructions;

Each weight marking on the syringe plunger will deliver sufficient paste to treat 100 kg bodyweight. Unlock the knurled ring by making a 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. Remove the plastic cap from the tip of the nozzle. Make sure the horse’s mouth contains no feed. 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.
