Contra-indications, warnings, etc
Withdrawal period
Meat and offal: 2 days.
Use during pregnancy, lactation or lay
The safety of the veterinary medicinal product has not been established during pregnancy and lactation in pigs. Use only in accordance with benefit-risk assessment by the responsible veterinarian.
Laboratory studies in animals have not produced any evidence of a teratogenic effect. Maternal toxicity in rodents has been observed at doses of 400 mg tylvalosin per kg bodyweight and above. In mice, a slight reduction in the foetal bodyweight was seen at doses causing maternal toxicity.
Special warnings for each target species
In severely diseased pigs, if water intake is reduced, pigs should be treated with a suitable injectable veterinary medicinal product prescribed by a veterinarian. At the recommended dose, lung lesions and clinical signs are reduced but infection with Mycoplasma hyopneumoniae is not eliminated.
Special precautions for use in animals
Official, national and regional antimicrobial policies should be taken into account when the product is used.
Good management and hygiene practices should be followed to reduce the risk of re-infection.
It is sound clinical practice to base treatment on susceptibility testing of the bacteria isolated from the animal. If this is not possible, therapy should be based on local (regional, farm level) epidemiological information about susceptibility of target bacteria.
Use of the veterinary medicinal product deviating from the instructions in the SPC may increase the risk of development and selection of resistant bacteria and decrease the effectiveness of treatment with other macrolides due to the potential for cross-resistance. An antibacterial with a lower risk of antimicrobial resistance selection, if available for the same indication, should be used for first line treatment where susceptibility testing suggests the likely efficacy of this approach.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Tylvalosin has been shown to cause hypersensitivity (allergic) reactions in laboratory animals; therefore, people with known hypersensitivity to tylvalosin should avoid contact with this product.
When mixing the veterinary medicinal product and handling the medicated water, direct contact, with eyes, skin and mucous membranes should be avoided. Personal protective equipment consisting of impervious gloves and a half-mask respirator conforming to European Standard EN 149 or a non-disposable respirator conforming to European Standard EN 140, with a filter conforming to European Standard EN 143 should be worn when mixing product. Wash contaminated skin.
In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.
