Immunosuppressive therapy is a type of treatment that is used to suppress or weaken the immune system in order to prevent it from attacking the body's own tissues. This type of therapy is commonly used in various medical conditions, including organ transplantation, autoimmune diseases, and some types of cancer. Immunosuppressive therapy can involve the use of medications such as corticosteroids, cytotoxic drugs, and monoclonal antibodies. These medications work by inhibiting the activity of immune cells or molecules that are involved in the inflammatory response. While immunosuppressive therapy can be effective in treating certain conditions, it can also have side effects, including an increased risk of infections and certain types of cancer. Therefore, it is important for patients receiving immunosuppressive therapy to be closely monitored by their healthcare providers.
