Jakafi is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat adults with intermediate or high-risk myelofibrosis, including primary myelofibrosis, post-polycythemia vera myelofibrosis, and post-essential thrombocythemia myelofibrosis. Jakafi is also referred to by its drug name, ruxolitinib.
Jakafi is a member of the kinase inhibitor class of drugs. It is believed to work in cases of MPN by blocking the activity of a family of enzymes known as Janus kinases, which are involved in cancer cell proliferation (when cancer cells grow quickly). Blocking their activity can result in the death of cancer cells.

Do not stop taking Jakafi suddenly. If you decide to stop taking Jakafi, consult your physician for a plan to reduce your dose gradually. Jakafi should be taken exactly as prescribed by a physician.
