Indications for use

For the treatment and control of gastrointestinal nematodes, lungworms, eyeworms, warbles, chorioptic and sarcoptic mange and sucking and biting lice in beef and non-lactating dairy cattle.

The product at the recommended dosage level of 500 μg ivermectin per kg bodyweight effectively controls the following parasites of cattle:




Inhibited L4

Gastrointestinal Roundworms

Ostertagia ostertagi

Haemonchus placei

Trichostrongylus axei

T. colubriformis

Cooperia spp.

Oesophagostomum radiatum

Strongyloides papillosus

Trichuris spp.


Dictyocaulus viviparus

Eye Worms

Thelazia spp.

Warbles (parasitic stages)



Hypoderma bovis

H. lineatum

Mange Mites

Sarcoptes scabiei var. bovis

Chorioptes bovis

Sucking Lice

Linognathus vituli

Haematopinus eurysternus

Solenopotes capillatus

Biting Lice

Damalinia bovis

The product given at the recommended dosage of 500 μg/kg bodyweight, controls infections with Trichostrongylus axei and Cooperia spp. acquired up to 14 days after treatment, Ostertagia ostertagi and Oesophagostomum radiatum acquired up to 21 days after treatment, and Dictyocaulus viviparus (lungworm) acquired up to 28 days after treatment. It also controls horn fly (Haematobia irritans) for up to 35 days after treatment.

To obtain optimal benefit from the persistent activity of the product for grazing animals it is recommended that calves which are set-stocked in their first grazing season should be treated 3, 8 and 13 weeks after the day of turnout. Studies have demonstrated that first-season grazing calves turned out to pasture in late April or May and treated with the product 3, 8 and 13 weeks after turnout can be protected from parasitic gastroenteritis and lungworm disease throughout the grazing season, provided they are set-stocked, all calves are included in the programme and that no untreated cattle are added to the pasture. Treated calves should also be monitored according to good husbandry practices.


The product has been formulated for topical application specifically in cattle. It should not be applied or administered to other species as severe adverse reactions, including fatalities in dogs, may occur. Do not apply to areas of skin which have mange, scabs or other lesions or to areas contaminated with mud or manure.

Special warnings for each target species

Rainfall before or after treatment will not affect the efficacy of the product. Do not apply to areas of skin which may have mange, scabs or other lesions or to areas contaminated with mud or manure. 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 bodyweight, misadministration of the product, or lack of calibration of the dosing device (if any).

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 Cooperia spp. in cattle within the EU. Therefore, the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Special precautions for use in animals

For external use only.

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


May be irritating to human skin and eyes and the user should be careful not to apply it to himself or other persons.

Amounts to be administered and administration route

Dosage: 1 ml per 10 kg bodyweight (based on a recommended dosage level of 500 μg/kg bodyweight).

Administration: The formulation should be applied along the mid-line of the back in a narrow strip between the withers and tailhead. To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of the dosing device should be checked.

Squeeze-Measure-Pour System (250 ml bottle and 1 litre pack)

•Attach the metering cup firmly to the bottle.

•Set the dose by turning the top section of the cup to align the correct bodyweight with the pointer on the knurled cap of the cup. When bodyweight is between markings, use the higher setting.

•Hold the bottle upright and squeeze it to deliver a slight excess of the required dose as indicated by the calibration lines.

•When the pressure is released, the dose automatically adjusts to the correct level. Tilt the bottle and dispense the solution.

•NOTE – FOR 1 LITRE BOTTLE AND 50 ML DIAL-A-DOSE CAP. When the 100 kg (10 ml) or 150 kg (15 ml) dose is required:

-turn cap to 10 ml or 15 ml mark

-squeeze bottle and fill to mark

-turn the pointer to “STOP” before dispensing the dose.

•The STOP position will close the system.

•Important – Keep upright when filling and during storage.

•Close container when not in use.

Below are some recent questions we've received regarding Ivomec Pour-On For Cattle, including answers from our team.

Can it be used in the wet?

F Johnston

I want to use Ivomec pour on with cattle when they are gathered for a TB test, but the forecast is giving rain. Can I still use it even in the rain?

  • Veterinary Advisor

Yes, thats fine. Rainfall before or after treatment will not affect the efficacy of the Ivomec.

Sharon Staple

Is this product the same as eprinex?

  • Veterinary Advisor

EPRINEX is the new endectocide from Merial, developed by the scientists who discovered IVOMEC. It is based on a new molecule, eprinomectin, which gives it greater potency, killing even more species of parasites than ivermectin (Ivomec). This also means that EPRINEX is able to kill more worms for longer than any other pour-on. Other unique properties of the product mean that it is the only endectocide with a zero milk withdrawal period and it can be used in all weathers, including heavy rain.

Use on horses


can I use ivomec pour on on horses

  • Non-Executive Director

This is not licensed or recommended. It has been tested and found not to be very effective unless you increase the dose quite a lot. Under-dosing will encourage the development of resistant strains of parasites. Generally it is not regarded as a good idea and we would not advise this product is used on horses.
