Special warnings

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 Dectomax Injection, or lack of calibration of the dosing device.

Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (Faecal Egg Count Reduction Tests). 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.

Special precautions for use in animals

Dectomax Injection does not contain an antimicrobial preservative. Swab the septum before removing each dose. Use sterile equipment and follow aseptic procedures.

When treating groups of animals, use only the Dectomax automatic dosing device and vented draw-off apparatus.

Syringes must be filled from the vial through a dry, sterile draw-off needle that has been placed in the vial stopper. Vial stoppers must not be broached more than 20 times. 

Special precautions to be taken by the person administering Dectomax Injection to animals.

Do not eat, drink or smoke whilst handling the product. Wash hands and exposed skin after use. Take care to avoid accidental self-administration – seek medical attention if any specific signs are noticed.

Advice to medical practitioners: in cases of accidental self-administration, specific symptoms have rarely been observed and therefore any cases should be treated symptomatically.

Special precautions for the protection of the environment

Doramectin is very toxic to dung fauna and aquatic organisms and may accumulate in sediments. The risks to aquatic organisms and dung fauna can be reduced by avoiding too frequent and repeated use of doramectin (and products of the same anthelmintic class) in cattle.

The risk to aquatic ecosystems will be reduced by keeping treated cattle away from water bodies for five weeks after treatment.

Contraindications

Extra-label use in dogs should be avoided as severe adverse reactions may occur. In common with other avermectins, certain breeds of dog such as collies are especially sensitive to doramectin and particular care should be taken to avoid accidental consumption of the product.
