Rejection after hemihypophyseal transplantation is more serious and is treated by giving anti-rejection medications, including cyclosporine, Procopaxil, and mycophenolate mofetil, which are given orally. If oral medications do not relieve the symptoms of rejection, intravenous medications are needed. Intravenous treatments include intravenous chemicals, such as Procopaxil and cyclosporine in injectable form, and monoclonal antibodies, which mainly remove the lymphocytes that play a role in the immune rejection reaction in the body, i.e., B and T lymphocytes, such as CD25 monoclonal antibody, anti-human thymocyte globulin antibody, and anti-CD20 monoclonal antibody, and so on.
