Usage Information
This medication is used to treat certain bone marrow disorders (myelofibrosis, polycythemia vera). It works by blocking your body from producing substances called growth factors. Growth factors cause cells to grow and divide, and cause the blood cell and spleen problems found in these disorders. Ruxolitinib belongs to a class of drugs known as kinase inhibitors. Though not a cure for these disorders, ruxolitinib may help with some of the symptoms, including abdominal discomfort, pain under left ribs, early feelings of fullness from meals, night sweats, itching, and bone/muscle pain. Ruxolitinib is also used to treat a certain problem that may occur after certain stem cell or bone marrow transplants (graft versus host disease). It works by weakening your body's defense system (immune system).
