I was diagnosed with primary myelofibrosis in 2022 at age 79. I started treatment with weekly injections to stimulate my bone marrow to produce more red blood cells. It worked for awhile. Next I received injections of Aranesp every 3 weeks. That worked for awhile too. Now my red blood cell count is the same as it was when I began treatment. My co pays are getting very expensive so I have decide to stop my treatment. I will still have blood work every 3 weeks and my red cell count will most likely drop down. What else can I do?
