Jakafi (Ruxolitinib phosphate) is a prescription medication used to treat bone marrow disorders like myelofibrosis caused by genetics and environmental factors. This drug is used to treat polycythemia vera in adults that are not responding to or cannot tolerate a medicine called hydroxyurea. Jakafi is also used to treat acute graft versus host diseases (aGVHD) in adults and children 12 years or older who are not responding to corticosteroids. This drug also treats chronic graft versus host disease (cGVHD) in adults and children older than 12 years who have taken one or two treatments that did not work well enough. You can use Jakafi alone or with other medications. The active ingredient in Jakafi is Ruxolitinib phosphate. Ruxolitinib phosphate belongs to a class of drugs called kinase inhibitors. It works by blocking the body from producing substances called growth factors. Growth factors cause cell growth and division, causing blood cell and spleen problems found in these disorders.
