The first injection may be given by the intravenous route.

Acute mastitis:

- Intramuscular or subcutaneous use:

The recommended dosage is 2 mg marbofloxacin/kg body weight (1 ml product/50 kg body weight) in a single daily injection, for 3 consecutive days. The first injection may also be given by the intravenous route.

-Intramuscular use:

The recommended dosage is 2 mg marbofloxacin/kg body weight (1 mg product/50 kg body weight) in a single daily injection,for 3 consecutive days.

To ensure administration of correct dose, body weight should be determined as accurately as possible, to avoid underdosing.

Special warnings for each target species


Special precautions for use

Special precautions for use in animals

Official and local antimicrobial policies should be taken into account when the 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 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.

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 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.

Adverse reactions (frequency and seriousness)

Transitory inflammatory lesions can occur at the injection site, without clinical impact, when administered via the intramuscular or subcutaneous route.

Administration by the intramuscular route may cause transient local reactions such as pain and swelling at the injection site and inflammatory lesions which may persist for at least 12 days after injection.

However, in cattle, subcutaneous route was shown to be better tolerated locally than intramuscular route. Therefore, the subcutaneous route is recommended in heavy cattle.

Use during pregnancy, lactation or lay.

Laboratory studies in rats and rabbits have not produced any evidence of teratogenic, foetotoxic or maternotoxic effects.

Safety of the product at 2 mg/kg body weight has been established in pregnant cows and in sucking calves and piglets when used in cows and sows. Can be used during pregnancy and lactation.

Safety of the product at 8 mg/kg body weight has not been established in pregnant cows or in sucking calves when used in cows. Therefore, the dose regimen should be used only according to the benefit/risk assessment by the responsible veterinarian.

Interaction with other medicinal products and other forms of interaction
