Viji,
The good thing is that today's thals do have choices, and the knowledge that the choice made today does not have to be the permanent course of action. If you are uncomfortable with Asunra at this time, it may be best to consider a temporary switch to another chelator, or a combination of chelators, where the dosage of each is less than what would be required of one chelator, alone. Would your doctor be willing to try kelfer at this age? Daily kelfer and desferal a couple times per week could be tried to see how her ferritin level responds. Another possibility would be to take a month off from Asunra and replace it with desferal. After one month, try re-introducing Asunra, and see if the creatinine and liver values are more stable this time. Keep in mind that most patients do see a rise in these values while using Exjade, so don't be too alarmed. If creatinine goes 33% higher than normal, it must be stopped immediately. Small increases should not be alarming. The small change in SGPT is not significant at all, and you will see this type of difference in level just by testing at different times of day.
Lena, you bring up an interesting point and one that again goes to less than forthcoming nature of Novartis on the subject of side effects of Exjade. Officially, Exjade has shown no different results in young children than in adults, but the anecdotal evidence we hear seems to imply that young children do have more problems with Exjade, than do older patients. We have nothing official to go by, but caution may be wise.
Viji, my advice is to take a short break from Asunra, and replace it with desferal for one month. Also, talk to your doctor about kelfer and whether it would be appropriate at this age.
