i. Special precautions for use in animals
Normal sterile precautions should be taken.

administered by the intravenous route and use of this route of
administration in calves is therefore not recommended.
Official and local antimicrobial policies should be taken into account

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 given in the SPC may
increase the prevalence of bacteria resistant to the fluoroquinolones
and may decrease the effectiveness of treatment with other quinolones
