How is immunosuppressant affect the body?

Immunosuppressants are medications that inhibit or reduce the immune response, which can help prevent the body from rejecting transplanted organs or treating autoimmune diseases. By dampening the immune system's activity, these drugs can increase the risk of infections and reduce the body's ability to fight off pathogens. While they can be life-saving in certain contexts, long-term use requires careful monitoring to balance the benefits against potential side effects and complications.
