Target species


Indications for use, specifying the target species

In cattle: For the treatment of infections with the following parasites

Gastro-intestinal worms -

Haemonchus placei (adult andL4)

Ostertagia ostertagi(adult and L4, including inhibited larvae)

Trichostrongylus axei (adult and L4)

Trichostrongylus colubriformis (adult and L4)

Cooperia punctata (adult only)

Cooperia oncophora(adult only)

Strongyloides papillosus (adult only)

Oesophagostomum radiatum,(adult and L4)

Lungworm (adult and L4) – Dictyocaulus viviparus.

Warbles (parasitic stages) – Hypoderma bovis, Hypoderma lineatum.

Mange mites – Sarcoptes scabiei var. bovis. The product may also be used to reduce infection of the mange miteChorioptes bovis, but complete elimination may not occur.

Sucking and biting lice – Linognathus vituli, Haematopinus eurysternus, Bovicola (Damalinia) bovis.

The product has persistent activity against infections acquired with Trichostrongylus axeiand Cooperia spp.up to 14 days after treatment, but only in the case of group treatment; Ostertagia ostertagiand Oesophagostomum radiatumup to 21 days after treatment; Dictyocaulus viviparusup to 28 days after treatment. It also has persistent activity against horn flies (Haematobia irritans) for up to 28 days after treatment; partial efficacy against Haematobia irritansmay last for up to 35 days post application.


Do not use in cases of known hypersensitivity to the active ingredient.

The product has been formulated for topical application specifically for cattle. It should not be administered to other species as severe adverse reactions including fatalities in dogs, may occur

Special warnings for each target species

Do not treat cattle when their hide is wet.

Do not treat cattle if rain is expected, as rain within 2 hours of treatment may reduce efficacy.

Do not apply to areas of skin which 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:

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 ivermectin hasbeen reported in Ostertagia ostertagiin cattle. Therefore, the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of this helminth species and recommendations on how to limit further selection for resistance to anthelmintics

Special precautions for use

Special precautions for use in animals

To avoid secondary reactions due to the death of Hypodermalarvae in the oesophagus or in the spine, it is recommended to administer the product at the end of warble fly activity and before the larvae reach their resting sites

Cases of intolerance with fatal outcome are reported in dogs, especially Collies, old English Sheepdogs and related breeds or crosses, and also in turtles/tortoises. Do not allow these species to come in contact with this product.

It is recommended to treat all animals within a herd or group.

The shedding of nematode eggs can continue for some time after treatment.

Close container after use.

Special precautions to be taken by the person administering the veterinary medicinal 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.

Operators should wear rubber gloves, boots, goggles and a waterproof coat when applying the product. Protective clothing should be washed after use.

As absorption through skin can occur, in the event of accidental skin contact, wash the affected area immediately with soap and water.

If accidental eye exposure occurs, flush the eyes immediately with water and get medical attention.

Do not smoke, eat or drink while handling the product.

Wash hands after use.

Use only in well ventilated areas or outdoors.

HIGHLY INFLAMMABLE, keep away from heat, sparks, open flame or other sources of ignition.

Adverse reactions (frequency and seriousness)

None known

Use during pregnancy, lactation or lay

Studies in laboratory animals have shown neither embryotoxic nor teratogenic effects with ivermectin.

Can be used during pregnancy and lactation provided that the milk is not intended for human consumption.

Please also see section 4.11

Interaction with other medicinal products and other forms of interaction

Do not combine ivermectin treatment with vaccination against lungworms. If vaccinated animals are to be treated, treatment should not be carried out within a period of 28 days before or after vaccination.

Amounts to be administered and administration route

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.


1ml per 10kg body weight (based on a recommended dosage level of 500 micrograms per kg body weight).


For topical application.

The formulation should be applied along the mid-line of the back in a narrow strip between the withers and tailhead.

The 250 ml and 1.0 litre packs must be used with appropriate dosing equipment.

Instructions for using the dispensing chamber:

Take dip tube and insert end into base of measuring cap with slotted end going to the bottom of the container.

Remove shipping cap from container.

Screw measuring cap onto container.

Select the correct dose rate by rotating the adjuster cap in either direction to position the dose indicator to the appropriate dose.

Gently squeeze the bottle to fill to level (any excess will return to the bottle) and then tip and apply to animal along backline.

Overdose (symptoms, emergency procedures, antidotes), if necessary

No signs of toxicity appeared in trials up to 3 times the recommended dose rate.

Clinical symptoms of ivermectin toxicity include ataxia and depression.

No antidote has been identified. In case of overdose, symptomatic treatment should be given.

Withdrawal periods

Meat and offal: 31 days.

Milk: Not permitted for use in lactating cattle producing milk for human consumption. Do not use in non-lactating dairy cows, including pregnant dairy heifers, within 60 days of calving.


ATCVet Code: QP54AA01

Pharmacotherapeutic group: endectocides, avermectins

Pharmacodynamic properties

Ivermectin is a mixture of two compounds belonging to the avermectin family, which are a macrocyclic lactone group of endectocides. Avermectin is a microbial metabolite of the soil organism Streptomyces avermilitis.

It is generally accepted that ivermectin exerts its action in two main ways, interference with neurotransmission and opening chloride ion channels. The effect of ivermectin on the parasitic CNS is considered to operate through glutamate-mediated chloride channels.Compounds of this class may also interact with other ligand-gated chloride channels, such as those gated by the neurotransmitter gamma-aminobutyric acid (GABA).

The opening of pre-synaptic chloride ion channels results in an efflux of chloride ions and depolarisation of the nerve terminal. These effects interfere with normal neurotransmission between nerves and muscles, resulting in parasite paralysis and eventual death.

Pharmacokinetic particulars

After administration of the product, the ivermectin is absorbed through the skin into the circulation of the treated animal. The maximum concentration in plasma occurs around 70 hours after application. Peak concentrations of about 7 ng/ml are obtained.

The residual antiparasitic effect of ivermectin is due to its persistence, which in turn is due in part to its long intrinsic half-life (t1/2β of approximately 210 hours), in part to its relatively high plasma protein binding (80% in cattle; binding remains relatively constant over time) and in part to the nature and type of the ivermectin formulation.

Elimination is in the faeces (via biliary excretion). Over 60% of the dose is excreted after 3 days.
