So True.........This happened to John when he was in the hospital for treatment for his bone marrow failure. They had to use an older IV anti-fungal which was very hard on the kidneys. They would not allow them to give him the newer formulation that was easier on him until they could show harm from the older medicine. He was so compromised from everything going on and they would not authorize a better, less damaging medicine until his kidneys were effected.
