Good question! I have been going over this in my mind for a couple of weeks. At first I felt that taking a chemo drug for a disease that has been stable for 30 years makes no sense. Then when I learned more about JAK2 I accepted that I am high risk and I have to do something. I am more afraid of the side effects of HU, although I realize that Pegasys has side effects too. But it’s not chemo! But now I am wondering if I made a too hasty decision, given the cost of Pegasys, the fact that HU seems to be a more common treatment and my concerns about injecting myself with a refrigerated product when I like to travel. But I just got a text that the Pegasys will be available tomorrow so I have to put this decision behind me.
