A UTI (urinary tract infection) is a growth of harmful bacteria — mostly E. coli — in the urinary tract. When these bacteria attach to the wall of your urethra or bladder, they can quickly multiply into an infection. Although some bacteria are flushed away when you urinate, once attached, they can grow and spread. Left untreated, infection can move from the bladder to the kidneys and do even more harm.
If you think you have a UTI, see your doctor right away to make sure and start treatment, which will likely be an antibiotic. You should take ellura with your antibiotic until the infection clears and then continue taking once daily to keep your urinary tract in check and to constantly flush out bad bacteria that could lead to another UTI.
