My daughter received IV Desferal during transfusions additionally to the subcuteneous use. It was given to her after the transfusion and in a very very diluted form ,( I think it was 2 vials of Desferal in 100 ml of saline) again over a period of 1 to 2 hours.
But Dr. Agarwal always said that that method does not help much, unless the drip can be continued for 12-16 hrs.
IV Desferal is given in cases of high iron overload over a period of 2-3 days to reduce the iron level faster.But in normal iron overloads, the subcutenious method works the best.. the idea is to keep the desferal in your body as long as possible.
If even diluted desferal is given through IV after the transfusion it has to be very very slow.. my daughter had loads of problems, even when the speed was slightly increased.. breathlessness, allergic reactions etc.. since the body was already loaded with the blood.
