Komal,
If your doctor doesn't agree, you should go along with what the doctor says, because the doctor needs to monitor you regularly for creatinine levels and must also run regular liver function tests. You are on a high dose of Asunra, so perhaps you should just take 1200 mg daily and see how well it works for you. In one month you can check to see if your ferritin is dropping. If it does, then continue with Asunra. If it doesn't drop, I would highly recommend switching to desferal 7 days per week until your iron levels get down into a safer range.
