If you suffer from a burning sensation while urinating, or you need to urinate frequently, you may have a urinary tract infection (UTI). UTI’s can be painful, but, when treated properly, are rarely a serious health threat. Cystex is the only over-the-counter urinary pain reliever with a dual-action formula that not only eases the pain and burning caused by a UTI, but also contains an antibacterial to help keep the infection from getting worse while you wait for your doctor’s appointment.
