1. Why am I using Jakavi?

Jakavi contains the active ingredient ruxolitinib. Jakavi belongs to a group of medicines called “JAK inhibitors”.

Jakavi is used to treat:

  • Myelofibrosis in adult patients:

Myelofibrosis (MF) is a disorder of the bone marrow, in which the marrow is replaced by scar tissue. The abnormal marrow can no longer produce enough normal blood cells and results in variety of symptoms such as fever, night sweats, bone pain, weight loss and a significantly enlarged spleen. Jakavi can reduce spleen size in patients with different forms of MF and relieve the symptoms.

  • Polycythemia vera in adult patients who are intolerant of or not controlled with hydroxyurea:

Polycythemia vera (PV) is a disorder of the bone marrow, in which the marrow produces too many red blood cells. The blood becomes thicker as a result of the increased red blood cells leading to a variety of symptoms such as itching (pruritus), headache, vision problems, severe burning pain in the hands or feet, and blood vessels clots. Enlarged spleen is also sometimes present. Jakavi can relieve the symptoms, reduce spleen size and the volume of red blood cells produced in patients with PV.

  • Acute and chronic graft-versus-host disease in patients 12 years of age and older:

Graft-versus-host disease (GvHD) is a complication that occurs after transplantation of blood or bone marrow from a healthy donor to a patient, for example when specific cells (T cells) in the donor’s graft (e.g. bone marrow) don’t recognize the host cells/organs and attack them.

There are two forms of GvHD: acute GvHD that usually develops soon after the transplantation and can affect skin, liver and gastrointestinal tract, and chronic GvHD, which develops later, around three months after the transplantation. Chronic GvHD frequently causes symptoms in the skin, liver, mouth, lungs, gastrointestinal tract, neuromuscular system, or genitourinary tract. Almost any organ can be affected by chronic GvHD.

Jakavi can reduce the symptoms of acute and chronic GvHD, leading to disease improvement and survival of the transplanted cells.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Your doctor may have prescribed it for another reason.
