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.

Where there is a risk of summer mastitis, additional management procedures, such
as fly control should be considered.

Special precautions for safe use in the target species:
Use of the veterinary medicinal 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 and
local antimicrobial policies should be taken into account when the veterinary
medicinal product is used.
Serious acute mastitis [potentially lethal] due to pathogens like Pseudomonas
aeruginosa, can occur after drying off despite preventive treatment. Good aseptic
practices should be thoroughly respected in order to reduce that risk; cows should be
housed in a hygienic paddock far from the milking parlour and regularly checked
several days after drying off.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Skin sensitisation may occur in persons handling the veterinary medicinal product;
care should be taken to avoid contact with skin.
Penicillins and cephalosporins may cause hypersensitivity 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.
1. Do not handle the veterinary medicinal product if you know that you are
sensitised, or if you have been advised not to work with such preparations.
2. Handle this veterinary medicinal product with care (especially persons with
skin damage) to avoid exposure. Wear gloves, wash hands in case of
contact with skin.
3. If you develop symptoms such as a skin rash following exposure, seek
medical advice and show the package leaflet or the label to the physician.
Swelling of the face, lips or eyes, or difficulty breathing are more serious
symptoms and require urgent medical attention.
Special precautions for the protection of the environment:
Not applicable.

None known.

Do not store above 25 C.
