Ciprofloxacin
"Cipro works great for me and is what I ask for.  I've always been given 500 mg twice a day.  Knocks out the pain and burning within 24 hours.  For those who say they always get a yeast infection... take a supplement of acidophilus every day to replenish the good bacteria in your system.  You won't get the yeast infection if you do this.  Take it several days after stopping the Cipro, and you'll be good to go!  "
