Ciprofloxacin
"Cipro is the only thing that works for me. I suffer from chronic urinary tract infections, despite my efforts of consistent 100% cranberry juice intake and using the bathroom after sex, I normally have 2-3 per year. Cipro usually kicks the awful urinary tract infection symptoms within a couple hours of my first dose, and I have complete relief within the first day. I'm lucky enough to have the meds on-hand due to the recurrent infections - typically only take for 3 days unless I'm seeing blood in my urine, then I take it for 5. Dose 500mg twice in the first day to kick the infection, and then I follow up with 500mg once per day through my 3 or 5 day. I don't usually have many side effects from the Cipro, maybe some fatigue and mild headache for a day but that's all."
