Reporting adverse events is important. It allows continuous safety monitoring of a

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:
•
class, 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 (which include fenbendazole) has been reported in
Teladorsagia, , and species in small
ruminants in a number of countries, including the EU. Resistance to fenbendazole
has been reported in cyathostomes in horses. 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.
Special precautions for safe use in the target species:
When incorporating this product into liquid feed, after thoroughly shaking the
suspension, measure the required volume of the suspension and add it to
approximately 10% of the liquid feed. Thoroughly mix this material and then add the
remaining liquid feed and once again mix to produce a homogenous dispersion.
Mix the medicated feed thoroughly prior to administration for example by rolling the
drum or barrel.
Intensive use or misuse of anthelmintics can give rise to resistance. To reduce this
risk, dosing programmes should be discussed with your veterinary surgeon.

product to animals:
