I'm sorry I can't help with this subject as I was dxed too late for this drug and have not researched it. However, I have too dumb and I do mean ignorant statements that may help or not. Is it possible to get this with a self injector that u just push. If not, u know the size of needle u need so why not buy them sep. and make them them replace the bad ones. It does not help with the pain but maybe the money. I'm in a an arean I know nothing about so if wrong pls ignore and know that I am so sorry for your problems and am mad that the stupit companies make equip. needles... that give us moe pain. We hurt enough w/o this mess. Take Care Sheena
