What Are The Side Effects Of Nitrofurantoin?

age 43 height 5 6 weight 135 I had a uti, bladder infection, and yeast infection about a month ago. They put me on Cipro. Monday went in because the uti is back, they couldn t get a good culture on the bacteria but put me on nitrofurantoin. Tuesday I was feeling a bit better but feel like I am going down hill again. I have a constant upset stomach, nothing seems to help. I have been drinking plenty of water. I have constant achy pain in on both of sides of my ribs, nausea and now am vomiting. I know this is a side affect of the drug, but it seems like each day I feel worse instead of better.
