Special precautions to be taken by the person administering the veterinary medicinal product to animals
Direct contact with the skin should be avoided. Personal protective clothing (gloves and overalls) must be worn when handling the product.
Porous gloves may let this product pass through to the skin. If the product makes contact with the skin underneath the glove, occlusive materials such as latex or rubber in gloves may enhance transcutaneous absorption of the product. Accidental spillage on the skin or eyes should be washed off immediately with plenty of water. Wash hands after treatment and before meals. Pregnant women and women of childbearing age should avoid contact with the product or should exercise extreme caution when handling this product. People suffering from progesterone dependent tumours (known or suspected) or from thromboembolic disorders should not use the product. Over-exposure effects: Accidental absorption could lead to disruption of the menstrual cycle, uterine or abdominal cramping, increased or decreased uterine bleeding, prolongation of pregnancy or headache. Direct contact with the skin should therefore be avoided.
In case of over-exposure, seek medical advice.
Other precautions regarding impact on 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.
