View in Spanish: Inmunodepresor

Immunosuppressant (IH-myoo-noh-suh-PREH-sunt)
An agent that decreases the body’s immune responses. It reduces the body’s ability to fight infections and other diseases, such as cancer. Immunosuppressants may be used to keep a person from rejecting a bone marrow or organ transplant. They are also used in the treatment of conditions marked by over-active immune responses, such as auto-immune diseases and allergies.
