Special precautions to be taken by the person administering the veterinary
medicinal product to animals
The product might induce irritation and sensitization.
People with known hypersensitivity to GnRH analogues or any of the excipients
should avoid contact with the veterinary medicinal product. The veterinary medicinal
product should not be administered by pregnant women, as an accidental self-
injection by the user cannot be excluded and because GnRH analogues have been
shown to be foetotoxic in laboratory animals. Women of childbearing age should
administer the product with special caution.
In the case of accidental self-injection, seek medical advice immediately and show
the package leaflet or the label to the physician.
In case of accidental contact with the skin, the corresponding area should be
thoroughly cleaned with soap and water, as GnRH analogues may be absorbed
through the intact skin. In case of contact with the eyes, they should be thoroughly
rinsed with water.

The simultaneous treatment of the product with PMSG or hCG can possibly lead to
an over-reaction of the ovaries.
No interactions were reported following administration of the product 48 hours after
