Special warnings

Use of the product should be based on susceptibility testing of the bacteria isolated from animal. If this is not possible, therapy should be based on local (regional, farm level) epidemiological information about susceptibility of the target bacteria.

Official, national and regional antimicrobial policies should be taken into account when the product is used. Use of the product deviating from the instructions 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.

This premix is intended for the manufacturing of solid medicated feed and cannot be used as it is; the incorporation rate of the premix in feed cannot be lower than 5kg/ton. Treatment should not exceed 5 days.

Skin sensitisation may occur. Avoid skin contact. Do not handle this product in case of known sensitization to active substance or any of the excipients. Handle this product with care to avoid exposure during incorporation of premix into feed and administration of feed to animals, taking all recommended precautions. Wear either a disposable half-mask respirator conforming to European standard EN 149 or a non-disposable respirator to European Standard EN 140 with a filter to EN 143, chemically resistant gloves, protective coveralls and goggles while incorporating the premix into feed. Wear gloves and do not smoke, eat, or drink when handling the product or medicated feed. Wash hands thoroughly with soap and water after use of the product or medicated feed. Rinse thoroughly with water in case of exposure. In case of accidental ingestion or the occurrence of symptoms characterized by skin rash, seek medical advice and show the package leaflet or label to the physician. Serious symptoms such as swelling of face, lips or eye lids, accompanied by breath difficulties, need immediate medical attention.

The safety of the product during pregnancy and lactation has not been studied in sows.  Use of the product during pregnancy and lactation is therefore not recommended.
