Do not use in cats aged less than 16 weeks.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
Do not use in cases of resistance against quinolones, since (almost) complete cross-
resistance exists against other fluoroquinolones.
Not suitable for infections resulting from strict anaerobes, yeast or fungi.

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.

A low urinary pH could have an inhibitory effect on the activity of marbofloxacin.
Pyoderma occurs mostly secondary to an underlying disease, thus, it is advisable to
determine the underlying cause and treat the animal accordingly.

Special precautions for safe use in the target species:
The fluoroquinolones have been shown to induce erosion of articular cartilage in
juvenile dogs and care should be taken to dose accurately especially in young
animals.
The fluoroquinolones are also known for their potential neurological side effects.
Cautious use is recommended in dogs and cats diagnosed as suffering from
epilepsy.
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. 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 fluoroquinolones and may reduce effectiveness of treatment
with other quinolones due to the potential for cross-resistance.
Official and local antimicrobial policies should be taken into account when the
product is used.
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.
In case of accidental ingestion seek medical advice immediately and show the
package leaflet or the label to the physician. Wash hands after use.
Special precautions for the protection of the environment:
Not applicable.

Fluoroquinolones are known to interact with orally administered cations (Aluminium,
Calcium, Magnesium, Iron). In such cases, the bioavailability may be reduced.
Do not use in combination with tetracyclines, macrolides because of the potential
antagonist effect.
When administered together with theophylline, the half-life and thus the plasma
concentration of theophylline increases. Hence, the dose of theophylline should be
reduced.

This veterinary medicinal product does not require any special temperature storage
conditions.
Store the blisters in the original container.
If the tablets are divided, the remaining halves and quarters should be kept in the
blister pocket.
