Ciprofloxacin
"Not long after taking this antibiotic in the hospital ER, my pain subsided. Before that, I had my first ever UTI at 29 years old, probably due to dehydration from failing to drink enough water on the Keto diet. Before that, I was urinating blood and chunks of white tissue. I was prescribed 2 weeks of this antibiotic twice a day at 500mg each. I have one day left and while I have had bad headaches, more importantly I still sometimes feel burning when urinating, so I don't even feel like it's totally working. I got off the Keto diet and have been drinking plenty of water since starting the antibiotics and I have avoided dairy like the plague around the time I need to take the pill. I never take antibiotics so I don't think I'm resistant."
