My husband has the same form of MDS. He has been on Lucpatercept injections for over 2 years. He started Revlimed/lenalidomide in February. He also has periodic blood transfusions. The chemo schedule for now is 2 weeks on/2 off. He started out daily, then white cell count tanked. Then it was every other day. Now it’s the 2 & 2. He feels awful when it’s 2 weeks on. So fatigued & short of breath. The docs keep trying different dosing, but it hasn’t been easy. The upside is that his hemoglobin has remained fairly steady, 8.7-9.5. Do your research on all of the side effects & try to be very proactive in your care!! Best to you!
