Shaziya,
Have you ever tried IV desferal? If you don't have the same allergic reaction, it might help to try it that way, along with Asunra.
If this isn't possible, talk to your doctor about trying combination of Asunra and deferiprone, keeping the Asunra dose the same and taking it in the morning, and then taking one dose of deferiprone late in the day. Close monitoring of your liver and kidney levels will be needed for this to be safe. I would take it cautiously. Has your ferritin been higher than this in the past?
