Beef and non-lactating dairy cattle.


4.2 Indications for use, specifying the target species


Enovex Pour-On is indicated for the effective treatment and control of the following gastrointestinal roundworms, lungworms, eyeworms, warbles, chorioptic and sarcoptic mange and sucking and biting lice in beef and non-lactating dairy cattle.


Gastrointestinal roundworms (adults and fourth stage larvae):

Ostertagia ostertagi (including inhibited O ostertagi), Haemonchus placei, Trichostrongylus axei, Trichostrongylus colubriformis, Cooperia spp, Oesophagostomum radiatum, Strongyloides papillosus (adult), Trichuris spp (adult).


Lungworms (adult and fourth stage larvae):

Dictyocaulus viviparus.


Eyeworms (adult):

Thelazia spp


Warbles (parasitic stages):

Hypoderma bovis, Hypoderma lineatum.


Lice:

Linognathus vituli, Haematopinus eurysternus, Solenopotes capillatus, Damalinia bovis.


Mange mites:

Chorioptes bovis, Sarcoptes scabiei var bovis.


Enovex Pour-On given at the recommended dose of 500 micrograms ivermectin per kg bodyweight controls infections with Trichostrongylus axei and Cooperia spp acquired up to 14 days after treatment, Ostertagia ostertagi and Oesophagostomum radiatum acquired up to 21 days after treatment and Dictyocaulus viviparis acquired up to 28 days after treatment.


It also controls horn flies (Haematobia irritans) for up to 35 days after treatment.


4.3 Contraindications


Enovex Pour-on has been formulated for specific use in cattle. It should not be applied or administered to other species, as severe reactions, including fatalities in dogs, may occur.


4.4 Special Warnings for each target species


Do not treat cattle when their hair or hide is wet. Do not treat cattle if rain is expected, as rain within 2 hours of treatment may reduce efficacy. Do not apply to areas of skin which have mange, scabs or other lesions or to areas contaminated with mud or manure.

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:


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 Cooperia onocophora in cattle within the EU, in Teladorsagia in cattle in developed countries such as New Zealand and Haemonochus in cattle 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.


4.5 Special precautions for use


i Special precautions for use in animals

5. pharmacological properties



Pharmacotherapeutic group: Avermectins


ATCvet Code: QP54AA01


Pharmacodynamic properties:


Ivermectin is a 22,23-dihydro derivative of an avermectin (which is a fermentation product produced by Streptomyces avermitilis) and consists of 2 homologues: B1a and B1b. It is a parasiticide with nematocidal, insecticidal and acaricidal activity documented in a wide range of domesticated animals.


Avermectins act to stimulate GABA mediated chloride ion conductance, causing irreversible neuromuscular blockade in nematodes, followed by paralysis and death.
