I sure would rather have 1 shot with the neulasta than the hassle of several with neupogen. I'll ask on Monday at my appointment if I can choose one or the other. As far as you know there's no medical difference in why you could use one and not the other? Sounds like, once again, my insurance company will control my life. Guess I shouldn't complain, I'm glad to have insurance. On the other hand, I'm sick of them making rules about our lives not based on our well-being, but based on their economics!
