Ivermectin should be administered at a dosage rate of 200 g per kg bodyweight
(2.5 ml per 10 kg bodyweight). It should be administered orally. It is
recommended that a suitably calibrated dosing gun is used to allow accurate
dosing especially in young animals.
To ensure administration of a correct dose, body weight should be determined as
accurately as possible; accuracy of the dosing device should be checked.
Do not mix with other products.
The product has been formulated specifically for use in sheep. It should not be
used in other species, as adverse reactions, including fatalities in dogs, may
occur.
The product is not for intravenous or intramuscular use.
Some animals may cough slightly immediately after treatment. This is a
temporary occurrence and is of no clinical consequence.
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 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
sheep and goats within the EU and it is common in in sheep
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.
