Assess bodyweight as accurately as possible before calculating the dosage.

Cases of intolerance with fatal outcome are reported in dogs, especially Collies, old English Sheepdogs and related breeds or crosses, and also in turtles/tortoises." Do not allow these species to come in contact with this product.
Close container after use.
Special precautions for use in animals
Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in effective 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 Cooperia oncophora in cattle within the EU, in Teladorsagia in cattle in developed countries such as New Zealand and Haemonchus 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.
As Ivermectin is extremely dangerous to fish and aquatic life, treated animals should not have direct access to surface water and ditches during treatment.
To avoid secondary reactions due to the death of Hypoderma larvae in the oesophagus or in the spine, it is recommended to administer the product at the end of warble fly activity and before the larvae reach their resting sites.
It is recommended to treat all animals within a herd or group.
The shedding of nematode eggs can continue for some time after treatment.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Highly flammable – keep away from heat, sparks, open flame or other sources of ignition.
Noromectin 0.5% w/v Pour-On Solution may be irritating to human skin and eyes and the user should be careful not to apply it to himself or other persons. Operators should wear nitrile rubber gloves and boots with a waterproof coat when applying the product. Protective clothing should be washed after use. If accidental skin contact occurs, wash the affected area immediately with soap and water. If accidental eye exposure occurs, flush the eyes immediately with water and get medical attention.
Do not eat, drink or smoke while handling the product. Wash hands after use. Use only in well ventilated areas or outdoors.
Adverse reactions (frequency and seriousness)
Undesirable effects are not expected when the product is used at the recommended dose rate.
Use during pregnancy, lactation or lay
Can be administered to beef cows at any stage of pregnancy or lactation.
Interaction with other medicinal products and other forms of interaction
Do not combine ivermectin treatment with vaccination against lungworms. If vaccinated animals are to be treated, treatment should not be carried out within a period of 28 days before or after vaccination.
Amounts to be administered and administration route
Ivermectin should be administered topically at 500 µg per kg bodyweight (1 ml per 10 kg bodyweight).
The formulation should be applied along the midline of the back in a narrow strip between the withers and the tailhead.
To ensure administration of a correct dose, body weight should be determined as accurately as possible; accuracy of the dosing device should be checked.

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.
