Treatment of Infections due to marbofloxacin susceptible bacteria:

In dogs:
treatment of infected wounds and abscesses
treatment of lower urinary tract infections due to Escherichia coli and Proteus mirabilis
prevention of surgical infections due to Staphylococcus intermedius, Escherichia coli and Pseudomonas aeruginosa.
In cats:
treatment of infected wounds and abscesses

4.3 Contra-indications
In growing pups of large or very large sized breeds, articular impairments (erosion of the articular cartilage) may appear during prolonged treatments with fluoroquinolones. In medium-sized growing dogs marbofloxacine is well tolerated up to doses of 4 mg/kg/day administrated during 13 weeks. However, it is not advised to administer the veterinary medicinal product to pups of large or very large breeds up to the age of 12 and 18 months respectively.
Do not use in bacterial infections with cross-resistance to other fluoroquinolones.
Do not administer to an animal previously found to be hypersensitive to marbofloxacine or other (fluoro)quinolone, or to any of the excipients of the product.

4.4 Special warning for each target species
See section 4.5.i)

4.5 Special precautions for use
i) Special precautions for use in animals

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 official and local antimicrobial policies should be taken into account when the product is used.
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.
Some fluroquinolones at high doses may have an epileptogenic potential and a depressor effect on cardiovascular function. Before pre-surgical administration to animals with a history of seizures or cardiovascular disorders, pre-surgical examination and anaesthetic protocol should be carefully considered.
Experimentally, marbofloxacin has not led to such epileptic reactions in dogs, including in case of over-dosages.
When given IV, the product should be injected slowly.

ii) Special precautions to be taken by the person administering the medicinal product to animals
In case of contact with skin, rinse with clear water.
In case of eye contact or accidental ingestion, rinse the eye or the mouth with clear water and seek medical advice.

4.6 Adverse reactions (frequency and seriousness)
In very rare occasions, neurological signs (seizures, ataxia, mydriasis, muscle tremor …), digestive signs (hypersalivation, emesis) and reactions at the injection site have been recorded after treatment. In case of severe reactions, a symptomatic treatment must be initiated.

4.7 Use during pregnancy and lactation
Studies on laboratory animals (rats, rabbits) did not reveal any teratogenic, embryotoxic or maternotoxic effect of marbofloxacin at the therapeutic dose. Safety has not been demonstrated in cats and dogs during pregnancy and lactation. Use during gestation or lactation only according to the benefit/risk assessment of the veterinarian
4.8 Interaction with other medicinal products and other forms of interaction
Specific studies conducted in dogs did not show interaction between marbofloxacin and anaesthetic agent such as isoflurane and medetomidine/ketamine combination.
In the absence of studies with other anaesthetic agents, interactions cannot be excluded.

4.9 Amounts to be administred and administration route
Prepare the solution by introducing the total content of the solvent vial into the lyophilisate vial.


Treatment of infected wounds and abscesses: 2 mg marbofloxacin / kg / day by a single subcutaneous injection, followed by oral administration for 6 days in the form of tablets.

Treatment of infections of lower urinary tract: 4 mg of marbofloxacin / kg / day by three subcutaneous injections at intervals of 4 days.

Prevention of surgical infections: 2 mg of marbofloxacin / kg by a single intravenous injection, just before the intervention.


Treatment of infected wounds and abscesses: 2 mg marbofloxacin / kg / day by a single subcutaneous injection for 3 to 5 days.

Prevention of surgical infections: 2 mg of marbofloxacin / kg by a single intravenous injection, just before the intervention.

4.10 Overdose (symptoms, emergency procedure, antidotes)
Symptoms observed in case of over-dosage are neurological: hypersalivation, lacrimation, trembling, myoclonia and convulsions. In case of severe reactions, a symptomatic treatment must be initiated. See section 4.6. Bradycardia could also be observed.

4.11 Withdrawal periods
Not applicable.


Pharmacotherapeutic group: anti-infective for systemic use (fluoroquinolone)
ATC Vet code: QJ 01 MA 93

5.1. Pharmacodynamics

Marbofloxacin is a synthetic bactericidal antimicrobial belonging to the fluoroquinolone group which acts by inhibition of DNA gyrase. It is effective against a wide range of Gram positive bacteria (especially Staphylococcus and Streptococcus) and Gram negative bacteria (especially Escherichia coli, Citrobacter freundii, Enterobacter cloacae, Serratia marcescens, Morganella morganii, Proteus sp, Klebsiella sp, Pasteurella sp, Moraxella sp, Pseudomonas sp).
In 2001, 100% of Pasteurella multocida and Staphylococcus intermedius were susceptible to marbofloxacin (with MIC90 = 0.052 µg/ml and 0.219 µg/ml respectively), as well as 83 %
Pseudomonas aeruginosa (MIC90 = 1.357 µg/ml) and 90 % E. coli
(MIC90 = 0.170 µg/ml).
The breakpoints are : MIC sensible strain ≤1 µg/ml ; MIC resistant strain ≥ 4µg/ml.

Intrinsic resistance to quinolones is observed in some microorganisms (yeast, fungi, strict anaerobes, some Pseudomonas). Acquired resistance is due to chromosome mutation. Since 1997, sensitivity of key pathogens to marbofloxacin remains very high.

5.2. Pharmacokinetics

After a sub-cutaneous administration to dogs and cats at the recommended dose of 2 or 4 mg/kg, marbofloxacin is rapidly absorbed and its bioavailability is close to 100 %. Maximum plasma
concentrations reached in the 2 species are about 1.5 µg/ml after sub-cutaneous administration
of 2 mg/kg in dogs and cats and 3 µg/ml at the dose of
4 mg/kg.
Marbofloxacin is weakly bound to plasma proteins (less than 10% in dogs and cats) and is widely distributed in the whole organism. In most tissues (skin, muscles, liver, kidney, lung, bladder, digestive tract), the tissue concentrations are higher than in plasma.
Marbofloxacin is eliminated slowly (elimination half life of about 13 hours in cats and dogs) and mainly in its active form in urine (2/3) and faeces (1/3).
