Low Hemoglobin ??

Hubby has been on tx for 22 weeks now - 2 weeks left.  He has been on Neupogen for 4 weeks because of low wbc.  His latest labs show low hemoglobin - 10.4   He also feels really bad.  He has tried to get up and do something and breaks out into a sweat, gets woosy and feels like he's going to throw up.  After laying down w/ice pack this passes but then he is really 'hammered'.  He started the tx at 205 and is now down to 170.  He is on 6 Rebetrol a day and .5 Interferon (1500 - I think that's the dose)
Does anyone have any experience w/low hemoglobin?  From what I've read he should have his rebetrol reduced.  The doc is out of town till tomorrow - great.  The person who gave me the lab results said that the hemoglobin was circled on the lab test but she doesn't know what that means.  I am going to try to get hold of a nurse today.
Thanks - everyone here is so great !  To be helping others slay this dragon..... you are all a godsend!
Keep the faith,
Paula
