iron deficiency anemia
"I have been taking this medication for about 3 weeks, and I am using a generic over the counter brand.  When I started the medication, I was told to be prepared for some slight constipation.  What I wasn't told was that this medication would cause me terrible diarrhea.  For the last week and a half I have been having watery diarrhea 5-7 times a day, and this side effect is more negative and has impaired my life more than the anemia did.  Got off the medication 3 days ago, but the diarrhea still hasn't stopped, and doesn't show any signs of stopping soon either.  Wanted to write this review for anyone who was only told to expect constipation like I was, it isn't always the case!!"
