Treatment of infestations by the following parasites sensitive to eprinomectin:
Gastrointestinal roundworms (adults and L4 larvae): Ostertagia ostertagi (including inhibited L4 larvae), Ostertagia lyrata (only adults), Haemonchus placei, Trichostrongylus axei, Trichostrongylus colubriformis, Cooperia sp. (including inhibited L4), Cooperia oncophora, Cooperia punctata, Cooperia pectinata, Cooperia surnabada, Bunostomum phlebotomum, Nematodirus helvetianus, Oesophagostomum radiatum, Oesophagostomum sp. (only adults), Trichuris discolor (only adults);
Lungworms: Dictyocaulus viviparus (adults and L4);
Warbles (parasitic stages): Hypoderma bovis, Hypoderma lineatum;
Mange mites: Chorioptes bovis, Sarcoptes scabiei var. Bovis;
Sucking lice: Linognathus vituli, Haematopinus eurysternus, Solenopotes capillatus;
Biting lice: Damalinia bovis;
Flies: Haematobia irritans.
The product protects the animals against reinfestations with:
- Nematodirus helvetianus for 14 days.
- Trichostrongylus axei and Haemonchus placei for 21 days.
- Dictyocaulus viviparus,,Cooperia oncophora, Cooperia punctata, Cooperia surnabada, Oesophagostomum radiatum and Ostertagia ostertagi for 28 days.
Contra-indications
This product is formulated only for topical application to beef and dairy cattle, including lactating dairy cattle. Do not use in other animal species.
Do not administer orally or by injection.
Do not use in case of resistance to the active ingredient.
Do not use in animals with known hypersensitivity to the active ingredient or to any of the excipients.
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 bodyweight, 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.
To date no resistance to eprinomectin (a macrocyclic lactone) has been reported in cattle within the EU. However resistance to other macrocyclic lactones has been reported in parasite species in cattle within the EU. Therefore, 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 use
i) Special precautions for use in animals
For external use only.
To avoid adverse reactions due to the death of warble larvae in the oesophagus or backbone, it is recommended to administer the product after the end of the swarming of the warbles and before the larvae reach their sites in the body; consult a veterinary surgeon to know the appropriate treatment period.
Not to be used in other species; avermectins can cause fatalities in dogs, especially Collies, Old English Sheepdogs and related breeds and crosses, and also in turtles/tortoises.
For effective use, the product should not be applied to areas of the backline covered with mud or manure. The product should be applied only on healthy skin.
ii) Special precautions to be taken by the person administering the veterinary medicinal product to animals
Avoid direct contact with the skin or eyes.
Wear rubber gloves and protective clothing when applying the product.
If accidental skin contact occurs, wash the affected area immediately with soap and water. If accidental eye exposure occurs, flush eyes immediately with water.
Wash hands after use.
Do not smoke, eat or drink while handling the product.
Should clothing become contaminated, remove as soon as possible and wash before re-use. In the event of ingestion, wash out mouth with water and seek medical advice.
People with known hypersensitivity to the active substance or to any of the excipients should avoid contact with the veterinary medicinal product.
iii) Other precautions
Eprinomectin is very toxic to dung fauna and aquatic organisms and may accumulate in sediments. Eprinomectin is persistent in soils.
The risk to aquatic ecosystems and dung fauna can be reduced by avoiding too frequent and repeated use of eprinomectin (and products of the same anthelmintic class) in cattle.
The risk to aquatic ecosystems will be further reduced by keeping treated cattle away from water bodies for three weeks after treatment.
Adverse reactions
Transient licking reactions, skin tremor at the administration site, minor local reactions such as the occurrence of dandruff and skin scales at the administration site have sometimes been observed.
Use during pregnancy, lactation or lay
Laboratory studies (rat, rabbit) have not produced any evidence of a teratogenic or embryotoxic effects due to the use of eprinomectin at therapeutic doses. The safety of the veterinary medicinal product in cattle has been established during pregnancy and lactation and in reproductive bulls. Can be used during pregnancy and lactation as well as in reproductive bulls.
Interactions
Since eprinomectin binds strongly to plasmatic proteins, this should be taken into account if it is used in association with other molecules having the same characteristics.
Amounts to be administered and administration route
Pour-on use.
To be administered topically in one single treatment at the dose rate of 500 μg eprinomectin per kg bodyweight equivalent to 1 ml per 10 kg bodyweight.
Apply the pour-on solution along the mid-line of the back in a narrow strip between the withers and tail head.
To ensure administration of a correct dose, bodyweight should be determined as accurately as possible and accuracy of the dosing device should be checked. If animals are to be treated collectively rather than individually, they should be grouped according to their bodyweight and dosed accordingly, in order to avoid under- and overdosing.
All the animals belonging to the same group should be treated at the same time.
FlexiBag (2.5 litre, 4.5 litre and 8 litre flexible pouch)
Connect an appropriate dosing gun to the FlexiBag as follows.
1 to 4. Connect one side of the tube to the coupling E-lock system draw-off and the other side to the dosing gun.
5 and 6. Plug the E-lock coupling system to the FlexiBag.
7. Gently prime the dosing gun, checking before use that all connections are tight.
Follow the gun manufacturer’s instructions for adjusting the dose and proper use and maintenance of the dosing gun.
When body weight is between marking, use the higher setting.
Overdose
No signs of toxicity have been observed after administration of up to 5 times the recommended dose. No specific antidote has been identified.
Withdrawal periods
Meat and offal: 15 days.
Milk: zero hours.
