intramuscular route. Therefore, the subcutaneous route is recommended in
heavy cattle.
The cap may be safely punctured up to 30 times. The user should choose the
most appropriate vial size according to the target species to treat.

Do not use in cases where the pathogen involved is resistant to other
fluoroquinolones (cross resistance).
Do not use in cases of hypersensitivity to the active substance, to any other
quinolone or to any of the excipients.

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.

The efficacy data showed that the product has insufficient efficacy for the
treatment of acute forms of mastitis induced by gram-positive bacteria.

Special precautions for safe use in the target species:
Official and local antimicrobial policies should be taken into account when the
veterinary medicinal product is used.
Fluoroquinolones should be reserved for the treatment of clinical conditions
which have responded poorly, or are expected to respond poorly, to other
classes of antimicrobials.
Whenever possible, fluoroquinolones should only be used based on
susceptibility testing.
Use of the product deviating from the instructions given in the SPC may
increase the prevalence of bacteria resistant to the fluoroquinolones and may
decrease the effectiveness of treatment with other quinolones due to the
potential for cross resistance.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals:
People with known hypersensitivity to (fluoro)quinolones should avoid contact
with the veterinary medicinal product.
Care should be taken to avoid accidental self-injection as it can induce a slight
irritation.
In case of accidental self-injection, seek medical advice immediately and show
the package leaflet or the label to the physician.
In case of contact with skin or eyes, rinse with plenty of water.
Wash hands after use.
