Noroclox DC (dry cow) is an off-white, stable intramammary suspension prepared under sterile conditions. Each single dose 4.5g syringe contains: Cloxacillin as Cloxacillin Benzathine 500mg.
In a long acting base with 3% Aluminium Stearate Benzathine Cloxacillin is a semi synthetic penicillin derived from 6-amino penicillanic acid. Noroclox DC is an intramammary suspension formulated for use in the dairy cow at the point of drying off, that is immediately after the last milking of the lactation in order to treat existing mastitis and to provide protection against further infections during the dry period. Noroclox DC is active against Gram-positive organisms associated with mastitis and is effective against Streptococcus agalactiae, Streptococcus dysgalactiae and other Streptococcal species, and Arcanobacterium pyogenes. As cloxacillin is not destroyed by staphylococcal penicillinase. Noroclox DC is active against penicillin resistant staphylococci which are an important cause of bovine mastitis. Noroclox DC maintains effective antibacterial levels in the dry cow udder for approximately four weeks, is bactericidal in action and is non-irritant in the udder tissue.
Dosage and Administration:
After the final milking of lactation, clean and disinfect the teats and introduce the contents of one syringe into each quarter via the teat canal.The syringe may only be used once. Part used syringes must be discarded.

In cows suffering from hypocalcaemia it may be necessary to withhold milk for a longer period than that stated above.
In such cases, milk should be withheld until the levels of antibiotics are below the maximum accepted residue levels, i.e. 0.03 mcg/ml. for cloxacillin.
Animals must not be slaughtered for human consumption during treatment. Cattle may be slaughtered for human consumption only after 35 days from the last treatment.
