More Information
Drug Name and Strength Cloxacillin 500 mg (as the benzathine salt)
Quantity 100 Tubes
Indication Routine treatment of dairy cows at drying off. Treatment of subclinical mastitis caused by organisms sensitive to cloxacillin, and reduction of the rate of new infections. Has been shown to reduce the level of subclinical mastitis during the dry period.
Contraindications Administration to lactating cows or cows expected to calve within 30 days of treatment; or to animals with a history of allergy to penicillin.
Actions Active against Gram-positive organisms associated with mastitis and is effective against Streptococcus agalactiae, Strep. dysgalactiae, other Streptococci and Corynebacterium pyogenes. As cloxacillin is not destroyed by staphylococcal penicillinase, Noroclox 500 is active against penicillin resistant Staphylococci which are an important cause of bovine mastitis. Noroclox 500 contains benzathine cloxacillin in a long acting aluminium stearate base. It is bactericidal in action and is nonirritant in the udder tissue.
Precautions Wear rubber gloves when infusing the suspension.
Dosage and Administration 1 syringe per quarter after the final milking before drying off. Milk the cow out normally; clean and disinfect the teats before infusion of the antibiotic. It is normally unnecessary and undesirable to introduce any further treatment during the dry period. Cows having a dry period of 30 days or less should not be treated as after calving milk will contain antibiotic residues.Syringes have a variable tip which allows for either partial or full insertion into the teat canal. Partial insertion is preferable as it may prevent unnecessary damage to the teat orifice and reduce the risk of infection. There is evidence that partial insertion can reduce the incidence of Staphylococcus aureus and Streptococcus uberis infections. Full insertion will be needed for larger teat orifices.
Storage Store below 25°C (air conditioning). Protect from light.
