Hi Debra,
John would get nauseated from Exjade also. How high is your Dad's FE level? You may want to either take a break from it for three weeks and start it up at a lower dose to see if that helps. Or, if he still has a central line in or a port, switch to desferral to see if he tolerates that better.
I hope they are monitoring his kidney and liver function very closely. John's kidneys did not like Exjade. It would cause a rise in his creatinine even at low doses.
You dad has been through a lot and it makes sense that his recovery will take longer. Continue with the "Deb Therapy"

. With John, we focused on restoring overall health to strengthen him. We did a lot with nutrition and energy work like acupuncture, chiropractic. We have done and continue with some herbal support and therapeutic essential oils.
