Posology:
1 ml per 10 kg bodyweight (based on a recommended dosage level of 500
mcg ivermectin per kg bodyweight).
Administration:
Pour-on use.
To ensure administration of a correct dose, body weight should be determined
as accurately as possible; accuracy of the dosing device should be checked.
The formulation should be applied along the mid-line of the back in a narrow
strip between the withers and tailhead.
500 ml and 1L VIRBAMEC Pour-On bottles
Both are equipped with a Squeeze-Measure-Pour System.
Attach the metering cup firmly to the bottle.
Set the dose by turning the top section of the cup to align the correct
bodyweight. 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.
Important- Keep upright when filling and during storage.
Close container when not in use and store in an upright position.
2.5 litre backpack and 5 litre backpack
These presentations are equipped with straps and a vented cap.
They should be used in conjunction with an appropriate dosing gun.
Connect the Pour-On applicator to the pack as follows:
•
•
the cap that has the draw-off tubing. Tighten the draw-off cap.
•
Follow manufacturer’s directions for correct use and care of the equipment.

Care should be taken to avoid the following practices because they increase
the risk of the development of resistance and could ultimately result in
ineffective therapy:
•
an extended period of time.
•
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 ivermectin (an avermectin) has been reported in
oncophora in cattle within the EU, in in cattle in developed
countries such as New Zealand and in cattle outside 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.
i. Special precautions for use in animals
Do not apply to areas of skin which have mange scabs or other lesions
or to areas contaminated with mud or manure.
Cattle should not be treated when the hair or hide is wet. Rain falling on
animals less than two hours after dosing may result in reduced efficacy.
However, under such conditions efficacy of VIRBAMEC Pour-On
against infections of in
cattle may be maintained. The influence of extreme weather conditions
on the long-term performance (persistent activity) of VIRBAMEC Pour-
On is not known.
Avermectins may not be well tolerated in all non-target species. 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.

Frequent and repeated use may lead to the development of resistance.
The product is effective in all hypodermosis stages, however, it is very
important to treat on time (at the end of warble fly season). The
elimination of Hypoderma larvae may cause negative reactions on the
host, when they are found in vital areas. Killing Hypoderma lineatum, if
found in perioesophageal tissue, may cause salivation and tympanism.
Killing Hypoderma bovis, if found in the vertebral canal, may cause
unsteadiness or paralysis. Cattle should be treated before or after those
stages of warble flies.
ii. Special precautions to be taken by the person administering the
veterinary medicinal product to animals
VIRBAMEC Pour-On 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, rubber boots and a
waterproof coat when applying the product. Protective clothing should
be washed after use.
If accidental skin contact occurs, 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 or eat while handling the product.
Wash hands after use.
Use only in well ventilated areas or outdoors.
