Ciprofloxacin
"I usually get 2-3 urinary tract infections per year.  This is my first time using Cipro. I started on it 3 days ago and have had no side effects.  The UTI is about 99% gone and I had major relief in the first 24 hours.  No problems with discomfort when urinating, just a slight tinge after I go but barely noticeable and my urine is clear without any odor.  I was hesitant to use it due to the side effects but am pleased that I have not experienced them."
