Hi Ritesh,
Nice to meet u on thalpal.
1. U r requirement of blood is xceeding the limits of blood transfusion quantity in a month i.e. 20ml/kg/month.
2. ur dosage of asunra is good. keep it continue and split the dosage
3. Ur on right path to reduce ferritin by adding desferal to ur chelation regimen.
Do not worry for the discoloration of urine, means it is reddish or not so much reddish.
To get adequate benefits of Desferal u have to add Vitamin C (max dose 250 mg/day) after one month of starting desferal, it will bring more iron out.
Looking on ur weight , u should take 5 vials at a time of desferal. Increase gradually the dosage of it from 3 to 4 vials then 5 vials in 2 days in week.
Ferritin fluctuate widely so do not have this report with fever or after bt. It takes much time to bring down ferritin.
As Andy said, Scan is important to know true iron load , and ferritin is not so much reliable.
Hope it help.
Feel free to ask any question.
I am also on same regimen. Desferal and Defrijet combo.
