Astrid,
My son was on exjade/desferal therapy for a year and it worked wonders for him. He is currently on exjade alone. I expect that exjade/ferriprox combination will yield good results - I hope that you do not experience any negative effects. One piece of advise I have is to begin slowly, at a low dose. I find iron accumulates quickly but seems to decline slowly. When beginning a new chelation plan - whether with a single drug or combination - it is best to start on a low dose, and if well tolerated then to increase as needed.
Best of luck,
Sharmin
