Is the drug Neulasta (pegrilgrastim) ever used during chemotherapy for Hodgkin Disease?

Im a little intimidated by my wives oncologist so I didn't press WHY Neulasta is not used for neutropenia when associated with Hodgkins Disease. I think it is due to the sky high wbc counts she had prior to chemo (15,000+). Is it that Neulasta would "restart the fire?" Is it never used? Or is it a last resort?
