infections.
Hiprex is used to treat infections of the urinary tract and stop them from coming back.The urinary tract is a collective name for the
parts of the body that produce, store and transport urine. These include the kidney, bladder and tubes called the ureter and urethra. It is

people undergoing certain medical procedures.
