Immunosuppressants are medications that help reduce the activity of the immune system. They are often prescribed to people who have received an organ transplant or those with autoimmune diseases, where the body mistakenly attacks its own cells. By dampening the immune response, these drugs help prevent rejection of the transplanted organ and manage symptoms of autoimmune conditions. While immunosuppressants can be very effective, they also come with risks. Since the immune system is less active, patients may be more susceptible to infections. It's important for individuals taking these medications to work closely with their healthcare providers to monitor their health and adjust treatment as needed.
