Special precautions for use
Special precautions for safe use in the target species:
Discard any uneaten medicated feed.
Part-consumed feed must be safely disposed of with other waste feed and not given to any other animals.
Special precautions to be taken by the person administering the veterinary medicinal product to animals:
The veterinary medicinal product should not be administered by pregnant women or women suspected to be pregnant. Women of childbearing age should handle the product with extreme care.
The veterinary medicinal product should not be handled by persons with known or suspected progesterone-dependent tumours or thrombo-embolic disorders.
Direct contact with the skin should be avoided. Personal protective equipment consisting of gloves and overalls must be worn when handling the veterinary medicinal product. Porous gloves may let this product pass through. Transcutaneous absorption may be even higher when the area is covered by an occlusive material, such as latex or rubber gloves. Accidental spillage on the skin should be washed off immediately with soap and water. Wash hands after treatment and before meals. In case of accidental contact with eye, rinse abundantly with water. Seek medical attention.
Effects of overexposure: Repeated accidental absorption could lead to disruption of the menstrual cycle, uterine or abdominal cramping, increased or decreased uterine bleeding, prolongation of pregnancy or headache.
People with known hypersensitivity to the active substance should avoid contact with the veterinary medicinal product.
Special precautions for the protection of the environment:
When spreading manure from treated animals, the minimum distance to surface water as defined in the national or local regulations has to be strictly respected, because the manure may contain altrenogest which could cause adverse effects in the aquatic environment.
