AN: 00290/2018
Enrofloxacin should be used where clinical experience, supported where possible by
sensitivity testing of the causal organism, indicates enrofloxacin as the active
substance of choice.
Chickens and turkeys
Via the drinking water.
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.
Always make sure that the entire dose offered has been consumed. 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. Determine the bodyweight of the birds as accurately as
possible in order to avoid underdosing.
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.
Calculate the daily quantity (ml) of the product required for treatment period as follows:
Total number of birds x Average body weight in kg x 0.1 = Total volume (ml) per day
The product may be put directly into the header tank or introduced via a water
proportioner pump.
Rabbits
10 mg/kg bodyweight per day for 5 consecutive days.
Calculate the daily quantity (ml) of the product required for treatment period as follows:

Revised: July 2018
AN: 00290/2018
Total number of rabbits x Average body weight in kg x 0.1 = Total volume (ml) per day
Medicated drinking water should be replaced every 24 hours.
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 known hypersensitivity to the active substance, other
(fluoro)quinolones or to any of the excipients.
Do not use for prophylaxis.
None known.
Treatment of Mycoplasma spp. infections may not eradicate the organism.

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.
Since enrofloxacin was first authorised for use in poultry, there has been widespread
reduction in susceptibility of to fluoroquinolones and emergence of resistant
organisms. Resistance has also been reported in Mycoplasma synoviae in the EU.
Whenever possible fluoroquinolones should only 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 fluoroquinolones due to the potential for cross
resistance.
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.
Avoid skin and eye contact.
Direct contact with the skin should be avoided because of sensitisation, possible
hypersensitivity reactions and contact dermatitis.
Wear gloves for this purpose.
Rinse any splashes from skin or eyes immediately with water.
Wash hands and exposed skin after use.
Do not eat, drink or smoke whilst using the product.

AN: 00290/2018
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.
Keep the container tightly closed.
After dilution, do not expose to direct daylight.
