Do not use in cats with a history or suspicion of malignant disorders, feline leukemia virus (FeLV) or feline immunodeficiency virus (FIV) infection, or hypersensitivity to cyclosporine. Atopica

People with known hypersensitivity should avoid contact with Atopica
®. Do not use with other immunosuppressive agents. It is important for cats to avoid exposure to
