Hi Lisa,
The Exjade dose is determined by your body weight and is usually prescribed from 20-40- mg/kg body weight, depending on the iron load, and how quickly the reduction in iron load is needed. Someone who is not currently transfusing and whose iron load is relatively low, can probably manage with the low 20 mg/kg daily dose, although 30 mg/kg would lower the ferritin faster. Should you have to resume Exjade, try starting out with a half dose for the first 1-2 weeks and see if your body does a better job tolerating it. Then raise your dose in increments until the desired dose is reached. As I mentioned, some people have also had success taking it in the late afternoon or evening on an empty stomach.
How many transfusions have you had? What was your ferritin level before you took Exjade the first time? Have you ever had any scans done of your liver or heart to measure the iron load? If your organs show iron load, you will probably need to use a chelation drug, but IP6 and green tea extract can add to this chelation and also help protect the organs from iron damage by their antioxidant effects. If you have no iron load in your organs, you can work to lower your iron with the natural supplements and see if this makes a noticeable difference.
