Contraindications
Do not use in other species; avermectins can cause fatalities in dogs, especially Collies, Old English Sheepdogs and related breeds and crosses, and also in turtles/tortoises.
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
Do not administer orally or by intramuscular or by intravenous injection.
Special warnings
Cattle, sheep and goats:
Unnecessary use of antiparasitics or use deviating from the instructions given in the SPC may increase the resistance selection pressure and lead to reduced efficacy. The decision to use the product should be based on confirmation of the parasitic species and burden, or of the risk of based on its epidemiological features, for each herd/flock.
Repeated use for an extended period, particularly when using the same class of substances, increases the risk of resistance development. Within a herd/flock, maintenance of susceptible refugia is essential to reduce that risk. Systematically applied interval-based treatment and treatment of a whole herd/flock should be avoided. Instead, if feasible, only selected individual animals or subgroups should be treated (targeted selective treatment). This should be combined with appropriate husbandry and pasture management measures. Guidance for each specific herd/flock should be sought from the responsible veterinarian.
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.
Confirmed resistance should be reported to the marketing authorisation holder or to the competent authorities.
If there is a risk for re-infection, the advice of a veterinarian should be sought regarding the need for and frequency of repeat administration.
Cattle:
Resistance to other macrocyclic lactones has been reported in parasite species in cattle within the EU. Therefore, use of this veterinary medicinal 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.
Sheep and goats:
Resistance to eprinomectin in parasite species in goats and sheep has been reported within the EU. Therefore, use of this veterinary medicinal 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
Special precautions for safe use in the target species:
Usual aseptic procedures for administration of a parenteral injection should be followed.
The death of warble fly larvae in the oesophagus or spinal cord canal may lead to secondary reactions. In order to avoid secondary reactions due to the death of Hypoderma larvae in the oesophagus or the spine, it is recommended to administer the veterinary medicinal product at the end of the period of fly activity and before the larvae reach their resting site.
Special precautions to be taken by the person administering the veterinary medicinal product to animals:
People with known hypersensitivity to eprinomectin or to any of the excipients should avoid contact with the veterinary medicinal product
The veterinary medicinal product causes serious eye irritation. Avoid contact with the eyes. Wash any splashes from eyes immediately with water.
This veterinary medicinal product may cause neurotoxicity. Care should be taken when handling the veterinary medicinal product to avoid self-injection. In case of accidental injection, seek medical advice immediately and show the package leaflet or the label to the physician.
Avoid contact with the skin. Wash any splashes from skin immediately with water.
Avoid oral exposure. Do not eat, drink or smoke while handling the veterinary medicinal product.
Wash hands after use.
The excipient glycerol formal may cause harm to the unborn child. In addition, the active substance eprinomectin can be transferred to breast milk. Pregnant/breast-feeding women and women of childbearing age should therefore avoid exposure to this veterinary medicinal product.
Special precautions for the protection of the environment:
Eprinomectin is very toxic to dung fauna and aquatic organisms, is persistent in soils and may accumulate in sediments.
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, sheep and goats.
The risk to aquatic ecosystems will be further reduced by keeping treated cattle, sheep and goats away from water bodies for two to five weeks after treatment.
Adverse events
Cattle:
Very common (>1 animal / 10 animals treated):
Injection site swelling1
Injection site pain2
1 Moderate to severe - typically resolves within 7 days but induration may persist for in excess of 21 days.
2 Mild to moderate - this reaction disappears without any treatment and does not impair the safety or efficacy of the veterinary medicinal product.
Sheep and goats:
Very common (>1 animal / 10 animals treated):
Injection site swelling1
Immediate pain upon injection2
1 Slight to moderate, typically resolves within 16 to 18 days.
2 Manifested by head movements and discomfort in sheep.
Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system.
See the package leaflet for respective contact details.
Use during pregnancy, lactation or lay
Pregnancy and lactation:
Cattle:
Can be used during pregnancy and lactation.
Sheep and goats:
The safety of eprinomectin during pregnancy in sheep and goats has not been tested. Use only according to the benefit/risk assessment of the responsible veterinarian in these species.
Interaction with other medicinal products and other forms of interaction
Since eprinomectin binds strongly to plasma proteins, this should be taken into account if it is used in association with other molecules having the same characteristics.
Administration routes and dosage
Subcutaneous use. For single administration only.
Administration of 0.2 mg of eprinomectin per kg bodyweight; corresponding to 0.1ml of the veterinary medicinal product per 10 kg bodyweight.
In goats, the volume per injection site should not exceed 0.6 ml.
50 ml and 100 ml vials
Do not exceed 30 broachings per vial. If more than 30 broachings are required, use of a draw off needle is recommended.
250 ml and 500 ml vials
Do not exceed 20 broachings per vial. If more than 20 broachings are required, use of a draw off needle is recommended.
Underdosing could result in ineffective use and may favour resistance development.
To ensure a correct dosage, body weight should be determined as accurately as possible. If animals are to be treated collectively, reasonably homogeneous groups should be set up, and all animals of a group should be dosed at the rate corresponding to the heaviest one.
Accuracy of the dosing device should be thoroughly checked.
Symptoms of overdose (and where applicable, emergency procedures, and antidotes)
Cattle, sheep:
After subcutaneous administration of up to 5 times the recommended dose, no adverse events were observed except a transient reaction (swelling followed by induration) at the injection site.
The safety of the veterinary medicinal product in goats has not been demonstrated in overdose studies.
Special restrictions for use and special conditions for use, including restrictions on the use of antimicrobial and antiparasitic veterinary medicinal products in order to limit the risk of development of resistance
Not applicable.
