Hi Mel,
i also had that type of reaction when I started. what I did was to reduce the dose initially and take it during my meal not afterwards. i also took it no later than 6.00 pm with food in the evening making sure that i did not go to bed for a while later.
I was supposed to have been on combination but didnt really use the desferal as I should but guess what my ferritin is now down to 471!!!!! Woo Hoo!!!!! Finally, I was getting depressed as sometimes it felt like it would never ever drop!!! It has never been so low before.
Combination is the best treatment especially when you are overloaded, I am living proof!!!!
So keep with it my friend, we are all in this together
