Nitrofurantoin
"I was put on Nitrofurantoin for seven days, taken four pills evenly throughout the day. I haven't finished my course, I have two more days to go but it has worked thus far. Previously, I was put on Trimethoprim for 3 days which I thought was helping my symptoms slightly but now I realize that it was worse medication since it made my backache badly unlike this new medication. The only side affect, I think is that I feel cold or I think I have had hot flushes (which weren't bad since I felt I was blushing throughout my face and it wasn't that hot). My UTI seems to be gone and I can't wait until I am done with this."
