To ensure a correct dosage, body weight should be determined as accurately as
possible.
Always make sure that the entire dose offered has been consumed. The intake of
medicated water depends on the clinical condition of the animals. In order to obtain
the correct dosage, the concentration of enrofloxacin may need to be adjusted
accordingly. The medicated water should be made up fresh each day just before it is
offered to the animals. The drinking water must be medicated throughout the
treatment period, and no other water source should be available.
Use only fresh pre-solutions, prepared every day before start of treatment. Pumping
systems should be checked constantly to assure proper medication. Empty the
water system and fill it with medicated water before starting the treatment.
The veterinary medicinal product may be put directly into the header tank or
introduced via a water proportioner pump.
Chickens and turkeys:
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
Based on the recommended dose and the number and weight of animals to be
treated, the exact daily quantity of the veterinary medicinal product should be

Do not use in cases of hypersensitivity to the active substance, to other
fluoroquinolones or to any of the excipients.
None known.
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 the national competent authority via
the national reporting system. See the package leaflet for respective contact details.
Treatment of Mycoplasma spp infections may not eradicate the organism.
Resistance has been reported in Mycoplasma synoviae in the EU.
Cross-resistance has been shown between enrofloxacin and other fluoroquinolones
in target pathogens, e.g. Escherichia coli.
Use of the veterinary medicinal product should be carefully considered when
susceptibility testing has shown resistance to fluoroquinolones because its
effectiveness may be reduced.

Special precautions for safe use in the target species:
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 identification and
susceptibility testing of the target pathogen(s). If this is not possible, therapy should
be based on epidemiological information and knowledge of susceptibility of the
target pathogens at farm level, or at local/regional level.
Not for use for prophylaxis.
Use of the veterinary medicinal product should be in accordance with official,
national and regional antimicrobial policies.
An antibiotic with a lower risk of antimicrobial resistance selection (lower AMEG
category) should be used for first line treatment where susceptibility testing suggests
the likely efficacy of this approach.
Narrow spectrum antibiotic therapy with a lower risk of antimicrobial resistance
selection should be used for first line treatment where susceptibility testing suggests
the likely efficacy of this approach.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
People with known hypersensitivity to fluoroquinolones should avoid contact with the
veterinary medicinal product.
Avoid contact with skin and eyes.
In case of accidental spillage onto skin or eyes, rinse immediately with water, seek
medical advice immediately and show the package leaflet to the physician. Wash
hands and exposed skin after use.
Do not eat, drink or smoke whilst using the veterinary medicinal product.
Special precautions for the protection of the environment:
Not applicable.
In vitro, an antagonism was shown, when combining fluoroquinolones with
bacteriostatic antimicrobial agents such as macrolides or tetracyclines and
phenicols. The simultaneous application of substances containing aluminium or
magnesium can impair the absorption of enrofloxacin.
This veterinary medicinal product does not require any special storage conditions.
Chickens: Meat and offal: 7 days.
Turkeys: Meat and offal: 13 days.
