Streptococci (including S. uberis).
Escherichia coli (including β-lactamase producing strains).
The syringe must only be used once. Partly emptied syringes due to the
unsuccessful use should be discarded.
The content of one syringe should be infused gently into the teat of the infected
quarter every 12 hours after each of three consecutive milkings.
Milk out the infected quarters. After thoroughly cleaning and disinfecting the teat and
teat orifice with the cleaning towels provided, gently infuse the contents of one
syringe into each affected quarter. Disperse the product by gentle massage of the
teat and udder of the affected animal.
In cases of infections caused by Staphylococcus aureus, a longer course of
antibacterial therapy may be required. Therefore overall treatment length must be at
the veterinarian’s discretion but should be long enough to ensure complete resolution
of intramammary infection.
AN: 01662/2024 & 01663/2024
Do not use in cases of hypersensitivity to the active substances, or to any of the
excipients.

isolated reports):
Hypersensitivity reaction
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
Do not use in cases associated with

Special precautions for safe use in the target species:
Swab teat end before treatment, with cleaning towels provided.
Recommendations for prudent use
The product should be used for treatment of clinical mastitis only.
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 (regional,
farm level) epidemiological information about susceptibility of the target bacteria.
Official, national and regional antimicrobial policies should be taken into account
when the product is used.
The combination of amoxicillin and clavulanic acid should be reserved for the
treatment of clinical conditions which have responded poorly, or are expected to
respond poorly, to other classes of antimicrobials.
Avoid use of the product in herds where no β-lactamase
strains have been isolated. Veterinarians should strive to use narrow spectrum
antibiotics if possible. Inappropriate use of the product may increase the prevalence
of bacteria resistant to β-lactam antibiotics and may decrease the effectiveness of
treatment with β-lactam antibiotics, due to the potential for cross-resistance.
The feeding of waste milk containing residues of antibiotics to calves should be
avoided up to the end of the milk withdrawal period, except during colostral phase,
because it could select antimicrobial resistant bacteria within the intestinal microbiota
of the calf and increase the faecal shedding of these bacteria.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
This product may cause skin and eye irritation. Avoid contact with the skin and eyes.
In the event of skin or eye contact rinse with plenty of clean water.
The cleaning towels supplied with the product contain isopropyl alcohol, which may
cause skin or eye irritation in some people.
The wearing of gloves is recommended during administration of the product and
when handling the cleaning towels.
Penicillins and cephalosporins may cause hypersensitivity (allergy) following
injection, inhalation, ingestion, or skin contact.
Hypersensitivity to penicillins may lead to cross reactions to cephalosporins and vice
versa. Allergic reactions to these substances may occasionally be serious.
Do not handle this product if you know you are sensitised, or if you have been
advised not to work with such preparations.
Handle this product with great care to avoid exposure, taking all recommended
precautions.
If you develop symptoms following exposure such as a skin rash, you should seek
medical advice and show the label or leaflet to the doctor.
AN: 01662/2024 & 01663/2024
Swelling of the face, lips or eyes or difficulty with breathing, are more serious
symptoms and require urgent medical attention.
Wash hands after use.
Special precautions for the protection of the environment:
Due to the endocrine-disrupting potential of prednisolone, the product may be
dangerous to fish and other aquatic organisms. Consequently, treated animals
should not have access to watercourses during the first 12 hours after treatment.
