medicinal product can be used on its own in dry cow management and mastitis

Selection of cows for treatment with the veterinary medicinal product should be
based on veterinary clinical judgement. Selection criteria may be based on the
mastitis and cell count history of individual cows, or recognised tests for the
detection of sub-clinical mastitis or bacteriological sampling.
udder quarter immediately after the last milking of the lactation (at drying off). Do
not massage the teat or udder after infusion of the veterinary medicinal product.
Care must be taken not to introduce pathogens into the teat in order to reduce
the risk of post-infusion mastitis.
It is essential that the teat is thoroughly cleaned and disinfected, with surgical
spirit or alcohol-impregnated disinfecting towels. The teats should be wiped until
the disinfecting towels are no longer visibly dirty. Teats should be allowed to dry
prior to infusion. Infuse aseptically and take care to avoid contamination of the
syringe nozzle. Following infusion it is advisable to use an appropriate teat dip or
spray.
Under cold conditions the veterinary medicinal product may be warmed to room
temperature in a warm environment to aid syringeability.

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.
It is important to observe strict aseptic technique for the administration of the
veterinary medicinal product because the veterinary medicinal product does not
have antimicrobial activity. Do not administer any other intramammary
veterinary medicinal product following administration of this veterinary medicinal
product. In cows that may have sub-clinical mastitis, the veterinary medicinal
product may be used following administration of a suitable dry cow antibiotic
treatment to the infected quarter.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals:
Wash hands after use.
The disinfecting towels provided with the intramammary veterinary medicinal
product contain isopropyl alcohol. Wear protective gloves if skin irritation due to
isopropyl alcohol is known or suspected. Avoid contact with eyes because
isopropyl alcohol can cause eye irritation.
Special precautions for the protection of the environment:
Not applicable.
Protect from light.
Milk: Zero hours.
