Nitrofurantoin
urinary tract infection
"Although I think I might have kidney stones instead of a UTI, (due to vast amounts of blood in my urine and no pain when I urinate) my only side effect is nausea. I can't say if it actually helped with symptoms because I still have side and belly pain after 7 days of being on it. Just because one person might have one side effect or allergic reaction doesn't mean the next person will. Everyone's body is different and what doesn't work for one person might work for the other."
