Are there any risks for taking immunoglobulins without prescription?

Requires a "script": Immunoglobulin replacement therapy is only available with a physician's prescription. They are given either intravenously or subcutaneously to either replacement if the patient's igg level is low with certain immunodeficiencies or as an immune system modulator (up or down regulator) in certain other conditions. All are significant ususally chronic diseases that should be managed by a specialist.
