There are several key reasons for the use of immunosuppressive therapy:
Preventing organ rejection: In patients who have undergone organ transplantation, the body's immune system may recognize the new organ as a foreign object and attack it. Immunosuppressive drugs help prevent this rejection. Autoimmune diseases: Conditions such as lupus, rheumatoid arthritis, and multiple sclerosis involve an overactive immune system attacking the body's own tissues. Immunosuppressive therapy can help control these reactions. Bone marrow transplants: These therapies are often used to treat certain types of cancer and blood disorders. Immunosuppressive medications are used to prevent graft-versus-host disease.
