If your insurance covers either drug then try the Neulasta first, since it's only 1 shot and visit. I had Neulasta at first during my chemo for BC and I reacted quite strongly---terrible all-over body aches, so much so that it hurt to be touched. Finally I asked if there was anything else to take and was told about Neupogen but I'd have to go in for 7 shots. It was worth the trips for me. I still had some bone aches but not as bad as with the Neulasta. Also during the last series of shots, I finally mentioned the pain to my acupuncturist and he was able to relieve the aches with one session! Wish I'd mentioned it much sooner.
Best to you in this journey.
