Presentation
Orbenin Dry Cow is an off-white suspension of cloxacillin as the benzathine salt in a long acting base with 3% aluminium stearate. It is presented in syringes containing 500 mg cloxacillin in 3 g of suspension.
Uses
To treat existing mastitis infections and to provide protection against further infections during the dry period.
Orbenin is active against Gram-positive organisms associated with mastitis. It is effective against Streptococcus agalactiae and other streptococcal species, penicillin-resistant and sensitive staphylococci and Actinomyces pyogenes. Orbenin is not destroyed by staphylococcal penicillinase. It is therefore active against penicillin-resistant staphylococci which are an important cause of mastitis.
Dosage and administration
Dosage
One syringe per quarter immediately after the final milking of lactation.
Administration
At drying off clean and disinfect the teat end thoroughly with surgical spirit following the last milking. Insert nozzle into the teat and apply gentle and continuous pressure until the suspension is expressed. After infusion it is advisable to dip each teat in an authorised teat dip.
Contra-indications, warnings, etc
Do not use in the lactating cow. If lactating cows are accidentally infused, milk should be withheld from the bulk supply for 30 days or less time if testing shows cloxacillin residues below the MRL of 0.03 mcg/ml.
