anemia
"I have had problems with anemia especially since my gastric by-pass surgery.  I have tried all the over the counter drugs and they upset my stomach and more important didn't change any of my blood work.  My nurse practitioner prescribed this medicine and I have been taking it for over a year.  My blood work has improved to almost all normal levels!  No upset stomach at all!  I would recommend anyone with this issue to try this medication."
