Indications for use, specifying the target species
The treatment and control of gastrointestinal nematodes, and lungworms and nasal bots of sheep
Gastrointestinal worms (adult and immature):
Haemonchus contortus, Ostertagia circumcincta, Trichostrongylus spp, Cooperia spp, Nematodirus spp including N. battus, Strongyloides papillosus, Oesophagostomum spp, and adult Chabertia ovina.
Inhibited larval stages and benzimidazole resistant strains of H. contortus and Ostertagia circumcincta are also controlled.
Lungworms (adult and immature):
Dictyocaulus filaria
Nasal bot (all larval stages):
Oestrus ovis
Contraindications
The product has been formulated specifically for use in sheep. It should not be used in other species, as adverse reactions, including fatalities in dogs, may occur.
The product is not for intravenous or intramuscular use.
Special Warnings for each target species
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
‚‚‚Underdosing, which may be due to underestimation 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 ivermectin (an avermectin) has been reported in Teladorsagia in sheep and goats within the EU and it is common in Haemonchus 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.
