"epo given when Hb IS ABOVE 10 is a bad idea above 11 is stupid and above 12 dangerous, "
What do you base this on? Many persons on HCV treatment are on procrit above 10.0 and for males, 11.0 can be quite low for hgb. Furthermore, many HCV patients are on maintenance doses of procrit for a significant portion of their treatment above the 10.0 level you've stated as being a bad idea to prevent hgb from dropping too low, which it would do without that procrit maintenance dose.
This is a previous discussion on procrit and ribavirin dosage reduction here and a number of the posters had procrit above that 10.0 mark.

I only went below 10.0 once. They reduced my ribavirin at that point at 13 weeks. After that week, my hepatologist put me on procrit and I stayed on it for most of the rest of my 34 weeks to keep me above 10.0 to avoid dosage reductions as the trial mandated they were required when hgb dropped below 10.0. When they took me off procrit for a time, my hgb dropped close to that 10.0 mark after getting up around 13 or so. He put me back on it and I stayed on it until treatment stopped for me. It had nothing to do with tolerability, I was managing okay with my hgb staying in the 10's most of the time. It had everything to do with avoiding dosage reductions and is a very valid use of procrit.
