urinary tract infection
"Don't let the bad reviews scare you from taking this drug! I was TERRIFIED of taking it because of all the horrible side effects it came with, but I thought I'd rather suffer temporarily than have my UTI turn into a kidney infection. My doctor prescribed me to take it for 3 days and the only side effect I experienced was fatigue, though it could have just been the lack of sleep I was getting. Other than that I was fine! My UTI symptoms disappeared within hours of the first dose. If you drink lots of water, take it on a full stomach, and watch what you eat, you'll be golden."
