I had an injection of Aransep after my one and only Blood transfusion the day before Thanksgiving. I felt so much better after that. My red blood count has been normal or close to it ever since.
I know that getting a transfusion can be scarey, but the hospital does a great job of matching and typing the blood, and monitor the transfusion for side effects.
Best of luck to your DH - and remember to take care of yourself.
