the mastitis and cell count history of individual cows or recognised tests for
the detection of subclinical mastitis or bacteriology sampling.
Special precautions for safe use in the target species:
It is good practice to observe dry cows regularly for signs of clinical mastitis. If
a sealed quarter develops clinical mastitis, the affected quarter should be
stripped out manually before appropriate therapy is instituted.
To reduce the risk of contamination, do not immerse the syringe in water.
Use the syringe only once.

order to minimize the risk of acute mastitis due to poor infusion technique and
lack of hygiene (see section 4.6), it is crucial to follow the aseptic technique of
administration described in section 4.9.

medicinal product may be used following administration of a suitable dry cow
antibiotic treatment to the infected quarter.
