immunosuppressant

An immunosuppressant is a medication that reduces the activity of the immune system. It is often used to prevent the body from attacking a transplanted organ or tissue, or to treat autoimmune diseases where the immune system mistakenly attacks the body's own tissues. By dampening immune responses, these drugs help reduce inflammation and tissue damage. However, they also lower the body’s ability to fight infections, so careful monitoring and management are essential when taking immunosuppressants.
