I took supplements for years. I have had serious stomach problems. I finally decided to stop the iron..after a week stomach discomfort was gone. I started them again. Problems returned.

I told my doctor. She recommended iron sulfate infusion. I had a reaction. Not anaphylaxis but serious enough. She changed it to iron sucrose, a milder less likely to cause reactions from of I V iron. I had no choice because I believe, doctor does not agree, that the prolonged use of the tablets caused a stomach bleed.

Iron sucrose caused some mild side effects. Slight rash and pain that was managed by Tylenol and Benadryl for 24 hours. My numbers went to 200. It did not go below 20 for a year. I can live with that.

That being said, how it might effect you is unknown. As I grow older I have had to make difficult decisions. I do a lot of research. Mayo clinic website says the iron tablets can cause bleeding in rare cases. So I weighed the cost and benefits. Once a year, 4 x one a week for Four weeks. The first time a different doc gave the full dose in one infusion. That was awful. So I recommend spreading it out if you try it. If pills are working then you are probably better off using them.

Good luck. We have to have iron. Mine went to 2 one time. It's tough.
