Zara,
Don't assume his iron load has risen based on ferritin tests. Ferritin is only for comparison because it is affected by other things like infection and inflammation, so you can never be sure that iron has risen when ferritin changes. See what his ferritin is at the next testing before changing any of his program. As he grows, his Asunra dose will need to rise, but his dose is fine right now. When the thal centers tested Exjade with food, the results were the same as without food (but actually better, because compliance increased). For a child, you may want to open the IP6 capsules and mix them with food or water, but don't mix with foods high in protein. If possible, it should be taken with liquid (not milk) on an empty stomach. At his weight, one capsule per day should be adequate.
