Is he in the hospital now? I would sure get him to someone else for a second opinion as soon as possible. The early treatments for acute failure can impact the long term and frankly, my experience is that most docs want to over dialyze. There are formulas they all follow and often that formula does not take the sensitive nature of an early acute failure into consideration. Regarding the vitamins and herbs, I'm not sure a pharmacist is the person to ask. When the forum allows me to post links I will send you an explanation of the changes I made that allowed me to come off of dialysis (all okayed by my doctor).
