Mange mites:
Psoroptes bovis
Sarcoptes scabiei var. bovis
Sucking lice:
Linognathus vituli
Haematopinus eurysternus
Solenopotes capillatus
This product may also be used as an aid in the control of biting lice (Damalinia
bovis) Chorioptes bovis, but complete elimination may not
occur.
Persistent Activity
This product given at the recommended dosage of 0.2 mg per kg bodyweight
controls re-infection with Haemonchus placei, Cooperia
Trichostrongylus axei acquired up to 14 days after treatment; Ostertagia
ostertagi and acquired up to 21 days after
treatment and Dictyocaulus viviparus acquired up to 28 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.
The product should be administered only by subcutaneous injection under the loose
skin in front of, or behind the shoulder.
The recommended dosage is 200 μg ivermectin and 2 mg clorsulon per kg
bodyweight corresponding to a single dose of 1 ml per 50 kg bodyweight. Divide
doses greater than 10 ml between two injection sites. 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.
Use of a sterile 17 gauge ½ inch (15 - 20 mm) needle is recommended. Replace
with a fresh sterile needle after every 10-12 animals or sooner if the needle becomes
soiled.
To ensure administration of a correct dose, bodyweight should be determined as
accurately as possible; accuracy of the dosing device should be checked. If animals
are to be treated collectively rather than individually, to avoid under- or over-dosing,
they should be grouped according to their bodyweight and dosed accordingly.

AN: 03561/2023 + 03700/2023
When the temperature of the product is below 5°C, difficulty in administration may be
encountered due to increased viscosity. Warming the product and injection
equipment to about 15°C will greatly increase the ease with which the product can be
injected.
When using the 250 ml and 500 ml pack sizes, use only automatic syringe
equipment.
For the 50 ml pack sizes, use of a multidose syringe is recommended.
Do not use intramuscularly or intravenously.
This product is a low volume product authorised for use in cattle.
The product must not be used in other species as severe adverse reactions,
including fatalities in dogs, may occur. Some dog breeds (Collies, Old English
Sheepdogs and related breeds or crosses) are at particular risk of severe adverse
reactions.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.

AN: 03561/2023 + 03700/2023
Transitory discomfort has been observed in some cattle following subcutaneous
administration. A low incidence of soft tissue swelling at the injection site has been
observed. These reactions disappeared without treatment.
For use only in beef cattle and non-lactating dairy cattle
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
Ostertagia ostertagi and Cooperia species in cattle within the EU. Therefore, the use
of this product should be based on local (regional, farm) epidemiological information
about susceptibility of these helminth species and recommendations on how to limit
further selection for resistance to anthelmintics.

Special precautions for use in animals
This product does not contain any antimicrobial preservative.
Swab septum before removing each dose.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
This product may cause eye and skin irritation.
Avoid contact with skin or eyes.
In case of skin or eye contact, wash exposed area with plenty of clean water. If
symptoms persist, seek medical advice.

and/or pain at the site of injection.
In case of accidental self-injection, seek immediate medical advice and show the
information leaflet or the label to the physician.

Other precautions
Ivermectin is highly toxic to aquatic organisms, dung beetles and sediment dwelling
insects. Long-term effects on dung insects caused by continuous or repeated use
cannot be excluded.
The risk to aquatic ecosystems and dung fauna can be reduced by avoiding too
frequent and repeated use of ivermectin and products of the same anthelmintic class
in cattle, sheep and pigs.
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.
Treated cattle should not have direct access to ponds, streams or ditches for 14 days
after treatment.
None known.
Protect from light.
Keep the container in the outer carton in order to protect from light.
Discard unused material.
None known.
