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:
•
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
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.
