medications that reduce the activity of the immune system
Immunosuppressants, also known as immunosuppressive drugs, are medications that reduce the activity of the body's immune system. They are often used to prevent the rejection of transplanted organs and to treat autoimmune diseases, where the immune system mistakenly attacks the body's own tissues. By dampening the immune response, these drugs can help manage conditions like alopecia areata, where the immune system targets hair follicles, leading to hair loss.
