An immunosuppressor is a medication that reduces the body’s ability to mount an immune response. It does this by interfering with the production or function of white blood cells, which are essential for fighting infection. Immunosuppressors are used to treat a variety of conditions, including autoimmune diseases, transplant rejection, and certain types of cancer. They may also be used to prevent organ rejection in people who have received transplants.
Immunosuppressors can cause serious side effects, so they are usually only prescribed when other treatments have failed or when the benefits outweigh the risks. These medications must be taken carefully and under close medical supervision. People who take them should be monitored closely for signs of infection and other complications.
