Thanks to both of you for your answers
The rescue drug for low ANC is neupogen. I began 2x per week injections at week 8 after my level went down to 300 (or 0.3). Depending of your current level once a week might be sufficient, but certainly the doc will guide you. I was told some experience an achy bone reaction, but I have had no reaction. The good thing is the ANC will rebound quickly for most people. Cost will depend on your insurance coverage and there might some assistance if needed.
What is your absolute neutrophil count (ANC)?
The only alternative, and it isn't a good one, is to lower the dose of interferon. I would avoid that at all costs. I was on neupogen for 5 months. At first I had a bit of leg pain that responded to tylenol. That stopped after the first week and I really didn't know I was taking it. It is very expensive.
