Dosage and administration

To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of dosing device should be checked.

A single treatment of 1ml (5mg doramectin) per 10 kg bodyweight, equivalent ot 500mcg/kg bodyweight, applied topically along the mid-line of the back in a narrow strip between the withers and tailhead.

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.

Contra-indications, warnings, etc

The product has been formulated for topical application specifically for cattle. It should not be administered to other species as severe adverse reactions may occur. Cases of intolerance with fatal outcome have been reported in dogs, especially Collies, Old English Sheepdogs and related breeds or crosses, and also in turtles/tortoise. Care should be taken to avoid ingestion of spilled product or access to containers by these other species.

Do not use in cases of hypersensitivity to the active substance or any of the excipients.

For external use only.

This product is to be applied to skin surface only.

Do not administer orally or parenterally.

Do not apply to areas of skin which are contaminated with mud or manure.

As is the case with similar products, in rare cases small skin lesions may occur at the administration site.

Dectomax Pour-On for Cattle may be irritating to human skin and eyes and users should be careful not to apply it to themselves or to other persons. Operators should wear 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 smoke or eat while handling the product. Wash hands after use.

Highly Flammable - Keep away from heat, sparks, open flame or other sources of ignition.

Environmental Safety

Extremely dangerous to fish and aquatic life. Do not contaminate ponds, waterways or ditches with the product or used container. Any unused product or waste materials should be disposed of in accordance with national requirements.

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 a 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 a different pharmacological class and having a different mode of action should be used.

To avoid secondary reactions due to death of Hypoderma larvae in the oesophagus or spine, it is recommended to administer Dectomax Pour-On at the end of the period of warble fly activity and before the larvae reach their resting sites. Consult your veterinary surgeon on the correct timing of treatment.

Withdraw Period

Meat and Offal: 35 days.

Do not use in lactating cows used to produce milk for human consumption, or in dry cows or pregnant dairy heifers within 60 days prior to calving.

Pharmaceutical precautions

Do not store above 30°C. Do not refrigerate. Protect from light.

If stored at temperatures below 4°C Dectomax Pour-On for Cattle may appear cloudy. Allowing to warm at room temperature will restore the normal appearance without affecting efficacy.
