Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

For the treatment and control of gastro-intestinal 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
bodyweight effectively controls the following parasites of cattle:
Gastrointestinal roundworms (adult and fourth stage larvae):
Ostertagia ostertagi
(including inhibited stage)
Haemonchus placei
Trichostrongylus axei T. colubriformis Cooperia
Strongyloides papillosus adult
Trichuris spp. adult
Lungworms (adult and fourth stage larvae):
Dictyocaulus viviparus
Eyeworms (adult):
Thelazia spp.

Revised: January 2024
AN: 02662/2023
Warbles (parasitic stages):
Hypoderma bovis
H. lineatum
Mites:
Sarcoptes scabiei var. bovis
Chorioptes bovis
Lice:
Linognathus vituli
Haematopinus eurysternus
Solenopotes capillatus
Damalinia bovis
The product, given at the recommended dosage of 500 micrograms per kg bodyweight,
controls infections with
after treatment,
the first 21 days after treatment and
the first 28 days after treatment. It also controls horn fly (Haematobia irritans) for up to
35 days after treatment.
For pour-on use.
Dosage: 1 ml per 10 kg bodyweight (based on a recommended dosage level of 500
micrograms per kg bodyweight).
Administration: The formulation should be applied along the mid-line of the back in a
narrow strip between the withers and tailhead. The product should be used with
appropriate dosing equipment. To ensure administration of correct dose, body weight
should be determined as accurately as possible; accuracy of the dosing device should
be checked.
Do not use in case of hypersensitivity to the active substance or to 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.
Undesirable effects are not expected when the product is used at the recommended
dose rate.
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 body weight, misadministration
of theproduct, 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. and Ostertagia ostertagi in cattle within the EU.

Revised: January 2024
AN: 02662/2023
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
HIGHLY FLAMMABLE - KEEP AWAY FROM HEAT, SPARKS, OPEN FLAME OR
OTHER SOURCES OF IGNITION.

careful not to apply it to themselves or others.
Operators should wear rubber gloves and boots with a waterproof coat when
applying the product. Protective clothing should be washed after use.

persists, seek medical advice and show the package leaflet or label to the physician.
If accidental eye exposure occurs, flush the eyes immediately with water and get
medical attention.
Wash hands after use.

Other precautions
This product is very toxic to aquatic organisms, sediment dwelling organisms, and dung
insects. Long-term effects on dung insects caused by continuous or repeated use
cannot be excluded.
Treated cattle should not have direct access to ponds, streams or ditches for 14 days
after treatment. The risk to aquatic ecosystems and dung fauna can be reduced by
avoiding too frequent and repeated use of this product and other products of the same
anthelmintic class. Therefore, the repetition of treatment in a pasture during a season
should be performed only in the absence of alternative treatment and on veterinary
advice.

clostridial vaccine.
Flammable - keep away from heat, sparks, open flame or other sources of ignition.
Bottles should remain upright during storage. Cloudiness may result when the product
is stored at temperatures below 0°C. Allowing the product to warm at room temperature
will restore the normal appearance without affecting efficacy.
Meat and offal: 15 days.
Do not use in animals producing milk for human consumption.
Do not use in non-lactating dairy cows including pregnant heifers within 60 days of
calving.
