Hi,
Do you also have the option of Ferriprox, because so far, in clinical trials, Ferriprox has shown to protect the heart more so than desferal and has also shown to reduce serum ferritin levels just as good as desferal. Not much research has been done on Exjade yet regarding iron in the heart but from the few trials that I have read, exjade also looks promising and offcourse so many people are taking it now. Take care and good luck.
