To the above--no, your body won't become dependant on the iron in the way you are thinking. It's like the missing ingredient in the recipe for making red blood cells. For whatever reaason you (and those of us here) must be out of it. I can't seem to absorb and store enough of it on my own hence the infusions. My dr.s have yet to discover the reason for that. IV iron is usually a last resort for those who have failed to respond to iron pills, dietary changes, etc. If you've not had it before the nurses will keep a close eye on you to make sure you tolerate it well. Have you read the other posts about IV iron?
