Ciprofloxacin
"I have had a lifetime of bladder infections and ciprofloxacin (although a little annoying because of the dairy and iron) it works wonders! By the second dose the pain is 95% gone. My advice take it with a handful of Cheerios and first thing in the morning and about 11 hours later at night when you haven't had too much dairy (like a glass of milk or a steak). I had no side effects and I always get it for at least one week to 10 days. I've taken just about every other one and I've had the infections come back. Ciprofloxacin is always my first choice!"
