Cattle and calves: by intramuscular injection, and restricted to 10 ml per injection site.
It is recommended to administer the product into different injection sites.
In cattle the preferred injection site is in the muscular tissue of the mid-neck region.
Horses and foals: injections can be given either intramuscularly or intravenously.
In foals, it is recommended to start the treatment with intravenous injections for 3 days and to follow with intramuscular injections.
To ensure the correct dosage the body weight should be determined as accurately as possible to avoid possible underdosing.

Contra-indications, warnings, etc
Do not use in animals which are known to be hypersensitive to cephalosporin antibiotics, other ß-lactam antibiotics or to any of the excipients.
Use of the product should be based on susceptibility testing of the bacteria isolated from the animal. If this is not possible, therapy should be based on local (regional, farm level) epidemiological information about susceptibility of the target bacteria. Use of the product
deviating from the instructions given in the SPC or the package leaflet may increase the prevalence of bacteria resistant to cefquinome and may decrease the effectiveness of treatment with cephalosporins, due to the potential for cross-resistance.
Hypersensitivity reactions to cephalosporins occur rarely. In horses, occasionally slight transient reactions may occur at the injection site. In cattle, use of the product may result in localized tissue reaction. Tissue lesions are resolved 15 days after the last injection.
There is no information on reproductive toxicity (incl. teratogenicity) in horses and cattle. Laboratory studies in rats and rabbits have not
shown any teratogenic, foetotoxic or maternotoxic effects. Use only according to the benefit/risk assessment by the responsible veterinarian.
Doses of 20 mg/kg in cattle, 1 mg/kg in horses and 3 mg/kg in foals twice daily have been well tolerated.

Operator warnings
Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact.
Hypersensitivity to penicillins may lead to cross sensitivity to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.

1. Do not handle this product if you know you are sensitized, or if you have been advised not to work with such preparations.
2. Handle this product with great care to avoid exposure, taking all recommended precautions.
3. If you develop symptoms following exposure such as a skin rash, you should seek medical advice and show the doctor this warning.

Swelling of the face, lips or eyes or difficulty with breathing, are more serious symptoms and require urgent medical attention.
In case of accidental contact with eyes, rinse immediately with copious amounts of water. Accidental spillage on the skin should be washed off immediately with soap and water. In case of accidental self-injection, seek medical advice immediately and show the package leaflet or the label to the physician.
