supergirl,
Our daughter's ferritin is around 600. My child takes exjade mixed with water. currently she takes 250 mg one time daily. To take the med, she bites into a chocolate piece (M&M, Lindt, Hersheys' or cadbury kind of milk chocolates or chocolate covered nuts whatever she decides) and then sips into the water mixed with exjade. after that she takes another bite of chocolate/chocolate covered nut and finishes the med and then last bite of chocolate. she gereally gets 3 M&Ms or 1 piece of milk chocolate or 1 piece of nut. when her dose goes up, we split the dose and follow this procedure morning and evening (after coming back from school but before dinner). Earlier we used to wait for 1/2 hr before eating anything but in last 6 months, we did not follow that. SO far it has been working great. The only problem has been to find a chocolate that she is not bored off.
Best of luck...
