Princess,
I am very sorry to hear about your daughter's ulcer. It is very likely that the ulcer was caused by the exjade. Had you been giving her exjade on an empty stomach? Also, we she getting a single dose or was she getting a divided dose twice daily?
Many people have found that taking half the dose twice daily is best, and taking exjade after a meal protects the stomach. We have noticed that our son's stomach troubles and subsided and his appetite has increased since we began giving him exjade immediately after dinner.
For the time being my advise to you would be to discontinue exjade until her stomach issues have subsided completely. Do you have ferriprox available to you? Our son used desferal for 8 years and did well with it (we are currently on exjade). If I were in your situation I would use an alternate method of chelation for an extended period, until the situation completely resolves. If and when you decide to resume exjade - I would recommend starting on a very very low dose, and event hat dose split so that she is taking it twice a day - after a meal each time.
With exjade, ferriprox and desferal - all blood labs need to be viewed carefully - changes in labs should be investigated as soon as possible.
I wish you the best - please keep us posted. I wish your daughter the best,
Sharmin
