Patient Education

Trilaciclib Injection


Trilaciclib injection is used to decrease the risk of myelosuppression (a decrease in red blood cells, white blood cells, and platelets) from certain chemotherapy medications in adults with small cell lung cancer (SCLC). Trilaciclib is in a class of medications called kinase inhibitors. It works by blocking the action of certain substances in the body to protect the cells in the bone marrow and immune system from damage during chemotherapy.
