Flouad I totally agree with you, it's important that the dosage is correct. If desferal is dosed too high it can be toxic and effects eyes and ears (once a Year we need to check them).
Years ago I had problems with my heart and the doctors were so afraid that I'd to be hospitalized and they gave me 6 gr. of desferal i.v. within 24 hours for 3 days. Within these 3 days I lost 60% of my eyesight on both eyes
I was so scared to become blind and asked them to stop the therapy. The doctor said they could live with these side-effects, of course they can..... what an answer from a doctor
But luckely we're the ones who decide and know better what is best for us. At the end they decreased the dosage to 3 gr. i.v. and my eyes recovered. With the right dosage, side-effects can be avoided.
