Zerofen Worm Drench 10% w/v Oral Suspension for Sheep and Cattle

Care should be taken to avoid the following practices becaue they increase
the risk of development of resistance and could ultimately result in ineffective
therapy:
•
over 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 benzimidazoles has been reported in
Haemonchus, Cooper and Trichostrongylus
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 for
anthelmintics.
