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:
Gastrointestinal Roundworms (Adult, L4 and Inhibited L4)
Ostertagia ostertagi
Gastrointestinal Roundworms (Adult and L4)
Haemonchus placei
Trichostrongylus axei
T. colubriformis

Dictyocaulus viviparus
Eye Worms (Adult)
Thelazia spp.
Warbles (parasitic stages)
Hypoderma bovis
H. lineatum
Mange Mites
Sarcoptes scabiei var. bovis
Chorioptes bovis
Linognathus vituli
Haematopinus eurysternus
Solenopotes capillatus
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.
The timing of treatment should be based on epidemiological factors and should be customised for each individual farm. A dosing program should be established by a qualified professional person.
Do not use in animals with known hypersensitivity to the active ingredient or any of the excipients.
The product has been formulated for topical application specifically in cattle. Do not apply or administer 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. 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 and other similar macrocyclic lactone products 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 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 nitrile rubber gloves and boots with a waterproof coat when applying the product. Wash all protective clothing after use.
If accidental skin contact occurs, wash the affected area immediately with soap and water. If irritation persists, seek medical advice and show the package leaflet or label to the doctor. If accidental eye exposure occurs, flush the eyes immediately with plenty of water and get medical attention.
Do not smoke or eat while handling the product. Wash hands after use. Use only in well-ventilated areas or outdoors.
Adverse reactions
Undesirable effects are not expected when the product is used at the recommended dose rate.
Use during pregnancy, lactation or lay
The product can be administered to beef cows at any stage of pregnancy or lactation provided that the milk is not intended for human consumption. It will not affect the fertility of cows and bulls and can be given to all ages of animals including young calves. Please also refer to ‘Special warnings for each target species’.
Not known. May be used concurrently with foot and mouth disease vaccine or clostridial vaccine.
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.
Dosing cup with Measure-Squeeze-Pour System (250 ml bottle and 1 litre pack)
The 250 ml pack contains one 25 ml dosing cup and one dip tube. The 1 litre pack contains one 60 ml dosing cup and one dip tube. Insert the dip tube into base of the dosing cup. Leave the "slotted end" of the dip tube exposed in the bottom of the bottle. Unscrew bottle cap from the top of the bottle. Screw the dosing cup onto the top of the bottle.
Measure: To select the correct dose rate, rotate the adjuster cap at the top of the cup in either direction to position the dose indicator to the weight of the animal you want to treat. When body weight is between markings, use the higher setting.
Squeeze the bottle gently to fill the dosing cup to the required dose. Release your grip and any excess will return to the bottle.
Pour: Apply the full dose by tipping and pouring along the back line of the animal until the dosing cup is empty. The dosing cup should not remain attached to the bottle when not in use. Detach the dosing cup after each use and replace the bottle cap.
