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 contact details.
Special precautions for use in animals
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.
Use of the veterinary medicinal product deviating from the instructions given in
the SPC may increase the prevalence of bacteria resistant to the product and
may decrease the effectiveness of treatment with other antimicrobials or classes
of antimicrobials due to the potential for cross-resistance.
Official, national and regional antimicrobial policies should be taken into account
when the veterinary medicinal product is used.
For intravenous administration the veterinary medicinal product should be
warmed to body temperature and injected slowly over as long a period as is
reasonably practical. At the first sign of intolerance the injection should be
interrupted and shock treatment initiated. Intravenous administration should be
used with extreme caution and only if therapeutically justified.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
The veterinary medicinal product may cause an allergic reaction in people
sensitised to sulfonamides. People with known hypersensitivity to sulfonamides
should avoid contact with the veterinary medicinal product.
If you develop symptoms following exposure such as a skin rash, you should
seek medical advice and show the doctor this warning. Swelling of the face, lips
or eyes or difficulty with breathing are more serious symptoms and require
urgent medical attention.
This product may cause skin and eye irritation.
Avoid contact with skin or eyes.
In case of skin or eye contact, wash exposed area with plenty of clean water. If
symptoms persist, seek medical advice.
In case of accidental self-injection, seek medical advice immediately and show
the package leaflet or the label to the physician.
Wash hands after use.
Laboratory studies in rabbits and rats with the excipient N-Methylpyrrolidone

injection.
