Symptoms
Myelofibrosis belongs to a group of diseases called myeloproliferative disorders. Many people with myelofibrosis get progressively worse, and some may eventually develop a more serious form of leukemia. Yet it's also possible to have myelofibrosis and live symptom-free for years.
Causes
Your Healthcare Professional may allow up to 6 months to see if Jakafi is working for you. If you do not see an improvement after 6 months of treatment, your Healthcare Professional may have you stop taking Jakafi. It is important to take Jakafi exactly as directed by your Healthcare Professional.
Prevention
You may have changes in your blood cholesterol levels. Your Healthcare Professional will do blood tests to check your cholesterol levels during your treatment with Jakafi.
