I was placed on Neupegin. I have needles (very small and painless) for 5 days before treatment. These are very expensive and you should ensure they are covered. In Canada, they cost $3000 for 10 injections (not including supplies)
I don't experience any side effects. They say the younger you are the more side effects, but I am 34.
