Neulasta/Neupogen

I'm still slogging through chemo, finished AC x 4 - currently on Docetaxol just had my second infusion.  Had to switch from Taxol due to an allergic reaction.  I am needing Neulasta as well as Neupogen to keep my neutrophils up.  Has anyone else required both these meds.  The bone pain is manageable, I'm just curious how common it might be to need both drugs and any long term effects.  I had bilateral mastectomies in November 2012. My chemo has been delayed more than 6 weeks due to low neuts.  Hopefully, with no more delays I'll be done with radiation by october.   thanks
