Before instillation, the udder should be milked out completely and the teat and its orifice should be thoroughly cleaned and disinfected.

SPECIAL WARNINGS

Special precautions for use

Special precautions for use in animals

In cows that may have subclinical mastitis, the product may be used following administration of a suitable dry cow antibiotic treatment to the infected quarter. In clinical trials, the compatibility of the product has only been shown with a cloxacillin containing dry cow preparation.

As with all dry cow intramammary treatments, it is good practice to observe dry cows regularly for signs of clinical mastitis. If a sealed quarter develops clinical mastitis the affected quarter should be stripped out manually before appropriate antibiotic therapy is instituted. To reduce the risk of contamination, do not immerse syringes in water. Use syringe only once.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillins may lead to cross sensitivity to cephalosporin and vice versa. Allergic reactions to these substances may occasionally be serious. Do not handle this product if you know you are sensitized to penicillins or cephalosporins, or if you have been advised not to work with such preparations. Handle this product with great care to avoid exposure. Use impervious gloves when handling and administering the product. Wash exposed skin after use.

If you develop symptoms following exposure, such as skin rash, you should seek medical advice immediately and show the package leaflet or the label to the physician. Swelling of the face, lips and eyes or difficulty in breathing are more serious symptoms and require urgent medical attention. Persons developing a reaction after contact with the product should avoid handling the product (and other cephalosporin and penicillin containing products) in future.

Wash hands after using the product.

Pregnancy and lactation

There is no evidence of reproductive toxicity (incl. teratogenicity) in cattle. Laboratory studies in rats and rabbits have not shown any teratogenic, foetotoxic or maternotoxic effects. Can be used during pregnancy. No adverse effects on fetuses were observed in clinical trials.

Do not use during lactation.

Interactions with other medicinal products and other forms of interaction

The neutralizing effect of bacteriostatic acting pharmaceuticals (macrolides, sulfonamides and tetracyclines) on bactericidal effect of cefquinome has not been evaluated yet. Therefore, there is no information about the safety and efficacy of this kind of association.

Overdose (symptoms, emergency procedures, antidotes), if necessary

No symptoms expected.

 

SPECIAL PRECAUTIONS FOR THE DISPOSAL OF UNUSED PRODUCT OR WASTE MATERIALS, IF ANY
