Trilaciclib Injection

What is this medication?

TRILACICLIB (TRYE la SYE klib) prevents low levels of red blood cells, white blood cells, and platelets caused by chemotherapy. It works by protecting the cells in your bone marrow that make these blood cells. This lowers the risk of infection and bleeding. It also reduces the need for blood transfusions.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
