I was given Zenprep Dr 40,000, and with insurance, I believe it was 12.00 for 3 months. Has it been cured, nope, but it has helped. Unfortunately, now they believe I have PSC as well (Primary Sclerosis Cholangitis) as well. I'm. hoping to have a definite diagnosis soon. Although, from what I have heard, there are really not very many ways to confirm.
