Dosage and administration

Administer only by topical application at the dose rate of 1 ml per 10 kg bodyweight, corresponding to the recommended dose rate of 0.5mg eprinomectin per kg bodyweight. The product should be applied topically by pouring along the backline in a narrow strip extending from the withers to the tailhead.
To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of the dosing device should be checked.

Contra-indications, warnings, etc

For animal treatment only.
This product is formulated only for topical application to beef and dairy cattle, including lactating dairy cattle. Do not use in other animal species; avermectins can cause fatalities in dogs. Do not administer orally or by injection.
Do not apply to areas of the backline covered 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:-
- 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 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.
Use during pregnancy and lactation
Milk from cows may be used for human consumption at any time following treatment with EPRINEX Pour-On for Beef and Dairy Cattle. Studies have demonstrated a wide safety margin. Studies conducted at three times the recommended use level of 0.5 mg eprinomectin per kg bodyweight had no adverse effect on breeding performance of cows or bulls. EPRINEX Pour-On for Beef and Dairy Cattle may be used in dairy cattle during all stages of pregnancy and lactation.
Safety in target species
Studies have demonstrated a wide safety margin.
Withdrawal periods
Meat may only be taken for human consumption from 15 days after the last treatment.
There is no milk withdrawal period for lactating dairy cattle. Milk from treated cows may be used for human consumption at any time following treatment with EPRINEX Pour-On for Beef and Dairy Cattle.

If accidental skin contact occurs, wash the affected area immediately with soap and water. If accidental eye exposure occurs, flush eyes immediately with water.
Do not smoke, eat or drink while handling the product.

Further information

Rainfall at any time before or after treatment will not affect the efficacy of the product.
While mite and louse numbers decline rapidly following treatment, due to the feeding habits of the parasites, in some cases several weeks may be required for complete eradication.
No signs of toxicity appeared when 8-week old calves were treated at up to 5 times the therapeutic dose (i.e. 2.5 mg eprinomectin per kg bodyweight), 3 times at 7-day intervals. One calf treated once at 10 times the therapeutic dose (i.e. 5 mg per kg bodyweight) in the tolerance study showed transient mydriasis. There were no other adverse reactions to treatment. No antidote has been identified.
