Tribex 100 mg/ml Oral Suspension for Cattle

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.
• Under dosing, which may be due to under estimation 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 triclabendazole has been reported in Fasciola hepatica in cattle.
Therefore, the use of this product should be based on local epidemiological
information about susceptibility of the and recommendations on
how to limit further selection for resistance to anthelmintics.

Special precautions for use in animals
