Special warnings

Special precautions for use in animals

Due to the likely variability (time, geographical) in the occurrence of resistance of bacteria for florfenicol, bacteriological sampling and susceptibility testing are recommended. If this is not possible, therapy should be based on local (regional, farm level) epidemiological information about susceptibility of the target bacteria. Use of the product deviating from the instructions given may increase the prevalence of bacteria resistant to florfenicol and may decrease the effectiveness of treatment with other amphenicols due to the potential for cross resistance. Official, national and regional antimicrobial policies should be taken into account when the product is used.
