Chanaverm 7.5% Oral Solution

The product may be given to young, pregnant and lactating animals, but due
regard must always be paid to the animals physical condition and the presence of
inter-current disease. When a dosing gun is used to administer the product, care
should be taken to avoid the occurrence of dosing gun pharyngitis.
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:
•
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 levamisole has been reported in Teladorsagia, Cooperia and
Trichostrongylus species in sheep. There are reports of resistance in
Haemonchus in sheep in various parts of the world other than the EU. Resistance
to levamisole has been reported in Teladorsagia species in cattle in New Zealand.
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.
