The product might induce irritation and sensitization. Persons with a known hypersensitivity to GnRH analogues or any of the excipients should not administer the product.

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.
