Special warnings

People with known hypersensitivity to any of the product ingredients should avoid contact with the veterinary medicinal product. To prevent any unpleasant effects, personal protective equipment consisting in rubber gloves, goggles and dust masks should be worn when administering the product. Wash hands and exposed skin after use.

In case of accidental ingestion or the occurrence of symptoms characterized by skin rash, seek medical advice. Serious symptoms such as face swelling, lips or eye lids, accompanied by breath difficulties, need immediate medical attention.

Due to variability (time, geographical) in susceptibility of bacteria for chlortetracycline, bacteriological sampling and susceptibility testing of microorganisms from diseased birds on farm are highly recommended. A high resistance rate of E.coli, isolated from chickens, against tetracyclines has been documented. Therefore the product should be used for the treatment of infections caused by E.coli only after susceptibility testing has been carried out. As eradication of the target pathogens may not be achieved, medication should therefore be combined with good management practices, e.g. good hygiene, proper ventilation, no overstocking.

Special precautions for the disposal of unused product or waste materials

For the environmental protection, medicines should not be disposed of via wastewater or household waste. Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal prod- ucts should be disposed of in accordance with local requirements.
