Hi MA,
Has the serum creatinine level also been tested? This is most important when using the deferasirox based drug and should be monitored monthly. It is very important in this case because it could be an infection or caused by asunra. If there is no rise in creatinine, it is most likely an infection. If the child is having symptoms of a urinary infection, asunra should be temporarily stopped. Please don't worry about the ferritin level. It is not significant. If any infection is present, even the sniffles, ferritin level will rise as a defense mechanism by the body. This has absolutely nothing to do with iron level in the body. Bacteria and viruses thrive on iron, so when the body has any infection, iron is sequestered in serum ferritin to prevent the infection from feeding off iron stores. This is a common reason for a sudden spike in ferritin levels. Also, the levels are not considered to be an accurate gauge of iron stores in the body, but are more useful for comparing over a period of time. There is also one other very common possibility for the ferritin increase, even if no infection is present, when using deferasirox. We have heard this same thing often from patients and parents after first starting Exjade. Exjade's chelation effects are often not seen right away because it is removing iron stores in tissue and free iron in the blood first. This is most important because the free iron and iron stores in the body are what pose the real risk. Iron stored in ferritin can do no harm, so you actually do want the drug to be attacking the iron that can do harm. It varies on how long before you may see a drop in ferritin, but for a two year old, it shouldn't be too long. Patients with a high iron load sometimes don't see a ferritin drop for a year or more, but the drug is working, which can be more accurately seen by liver and heart scans, but these will come later than this young age.
I would suggest splitting the dose in two and taking half in the morning and half in the evening. Recent research shows that deferasirox can be crushed and mixed in various foods. One thing that is very important with all chelators but even more so with deferasirox is staying well hydrated. Make sure your child gets plenty of fluids, especially water. Do not allow this to be neglected. This drug can have side effects in the kidneys and liver and keeping the kidneys well irrigated is very important to helping prevent side effects.
