What Jakavi is and what it is used for
Jakavi contains the active substance ruxolitinib.
Jakavi is used to treat adult patients with an enlarged spleen or with symptoms related to myelofibrosis, a rare form of blood cancer.
Jakavi is also used to treat patients with polycythemia vera who are resistant to or intolerant to hydroxyurea.
How Jakavi works
Enlargement of the spleen is one of the hallmarks of myelofibrosis. Myelofibrosis is a disorder of the bone marrow, which means that the marrow is replaced by scar tissue. The abnormal bone marrow can no longer produce enough normal blood cells, which leads to a significant increase in the size of the spleen. By blocking the activity of certain enzymes (called Janus kinases), Jakavi can reduce the size of the spleen in patients with myelofibrosis and relieve symptoms such as fever, night sweats, skeletal pain, and weight loss in patients with myelofibrosis. Jakavi can help reduce the risk of serious blood or vascular complications.
Polycythaemia vera is a disease of the bone marrow, in which the bone marrow produces too many red blood cells. The blood becomes thicker due to the increased number of red blood cells. Jakavi can relieve symptoms, reduce spleen size and the volume of red blood cells produced in patients with polycythemia vera, by selectively blocking enzymes called Janus kinases (JAK1 and JAK2), potentially reducing the risk of serious blood or vascular complications.
Ask your doctor if you are wondering how Jakavi works or why you have been prescribed it.
