When do doctors usually give iron infusions (shots or IVs) for Anemia?

First off, let me say that I totally feel for you. As for now, if you are that weak, I say get to the hospital now. Anemia is nothing to play with , so if you feel that crappy, you should really be treated. the lowest my hbg has been is 7.4, and i had NO idea that it was that low. Anyhow, it takes a while for your levels to get to normal. Increase your iron intake in your diet instead of just taking the pills. I hope this helps a little bit
