Pain when you urinate or blood in your urine can be signs of a urinary tract infection, commonly referred to as a "UTI" or "bladder infection". This can also be a sign of a kidney stone. Most urinary tract infections will need to be treated with antibiotics. If you have symptoms of a UTI, you should see a health care provider. AZO is a medicine that is available without a prescription. It is not an antibiotic but it is a pain reliever for the urinary tract and can help you be more comfortable before you can see a health care provider.
