Norocillin is indicated for use in cattle, sheep and pigs in the treatment of systemic infections caused by or associated with organisms sensitive to penicillin. In vitro tests have shown the following organisms to be sensitive: Arcanobacterium (Actinomyces) pyogenes, Erysipelothrix rhusiopathiae, Listeria, Mannheima haemolytica, Pasteurella multocida, Staphylococcus spp (non-penicillinase producing) and Streptococcus spp.

Norocillin is recommended, therefore, in the treatment of diseases caused by susceptible organisms including: Erysipelas; navel/joint-ill; respiratory tract infections including pneumonia and atrophic rhinitis; listeriosis; septicaemia; urogenital tract infections and the control of secondary bacterial invaders in diseases of primary viral origin.

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 epidemiological information.


Norocillin should be administered by the intramuscular route after shaking to ensure resuspension. The recommended dose rate is 1ml/30kg bodyweight daily for 3-5 days. To ensure the correct dosage, bodyweight should be determined as accurately as possible to avoid underdosing.
