urinary tract infection
"My experience is not one size fits all. I have a kidney transplant and because of that I should have been given this medicine at 250 mg. Instead they prescribed 500. I was very sick to the point of fever so I didn't do my own research that day. I just took the meds and tried to sleep. It was the second day that I realized I got very sick and vomited each time and when I researched I found I should not take 500 mg because of my transplant my body could not break it down. I was then prescribed it at 250 and stopped vomiting. It took my infection completely away."
