tanks, or via water proportioner systems.
10 mg enrofloxacin/kg bodyweight per day for 3-5 consecutive days.
Treatment for 3-5 consecutive days; for 5 consecutive days in mixed infections and
chronic progressive forms. If no clinical improvement is achieved within 2-3 days,
alternative antimicrobial therapy should be considered based on susceptibility testing.
Medication of the water supply should be continuous during the treatment period and
no other source of water should be available.
Medicated water should be made every day, immediately prior to provision. Carefully
calculate the total body mass to be treated and the total daily water consumption
before each treatment.
The uptake of medicated water depends on age and clinical condition of the birds,
ambient temperature, and light regime. In order to obtain the correct dosage the
concentration of the product should be adjusted accordingly. Taking into
consideration that 10 mg enrofloxacin per kg body weight corresponds to 0.1 ml of
the product per kg body weight; the following calculation should be made to provide
the required amount of the product per litre of drinking water:
0.1X
Average bodyweight
of birds to be treated

of birds

Care should be taken that the intended dose is completely ingested.
Use appropriate and properly calibrated dosing equipment.

Do not use in birds producing eggs for human consumption.
Do not use for prophylaxis.
Do not use when resistance/ cross-resistance to (fluoro)quinolones is known to occur
in the flock intended for treatment.

Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.

Treatment of Mycoplasma spp infections may not eradicate the organism.

Special precautions for use in animals
Since enrofloxacin was first authorised for use in poultry, there has been widespread
reduction in susceptibility of
organisms. Resistance has also been reported in Mycoplasma synoviae in the EU.
Before use, header tanks should be emptied, thoroughly cleaned and then filled with
a known volume of clean water before adding the required amount of product. The
resulting mixture should be stirred.
Before use, header tanks should be inspected at regular intervals for presence of
dust, algae formation and sedimentation.
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.
Wherever possible, fluoroquinolones should be used based on susceptibility testing.
Use of the product deviating from instructions given in the SPC may increase the
prevalence of bacteria resistant to fluoroquinolones and may decrease the
effectiveness of treatment with other quinolones due to the potential for cross
resistance.
If there is no clinical improvement within two to three days susceptibility testing
should be repeated and therapy should be changed, if appropriate.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Wear impervious gloves when handling the product.
Direct contact with the skin should be avoided because of sensitisation, contact
dermatitis and possible hypersensitivity reactions.
In the case of eye or skin contact, rinse the affected area with clean water and if
irritation occurs, seek medical attention.
Wash hands and exposed skin after use.
Do not eat, drink or smoke whilst using the product.
People with known hypersensitivity to fluoroquinolones should avoid contact with the
product.
AN: 00964/2024 + 01297/2024Page 3 of 6
Concurrent use of enrofloxacin with other antimicrobials, tetracyclines and macrolide
antibiotics, may result in antagonistic effects.
Absorption of enrofloxacin may be reduced if the product is administered together
with substances containing magnesium or aluminium.
Do not combine enrofloxacin with steroidal anti-inflammatory products.
This veterinary medicinal product does not require any special storage conditions.
