I suffer from chronic anemia and now have iron infusions every year, or more if my levels drop. I also take Vitamin B shots every month. I now have blood work done every 3 months to check levels, so it never gets very low. The infusions are done every week for 4-6 weeks, depending on how low the level is. It is an easy fix now that we know what is happening. Also, I tried iron tablets and they didn't make any difference, so that was a waste of 2 months!
