Welcome to Connect, @palermo1. Thank you for sharing your son’s experience with receiving blood transfusions for his anemia and the need for chelation. While a life savers, the transfusions can leave the side effect of too much iron being stored in the body. Chelation is a means to remove the iron.
Beta thalassemia intermedia is an inherited condition. Do other members of your family have this as well? I’ve read that a bone marrow transplant can be a possibility of a long term treatment. How long has your son had his symptoms?
