Phenazopyridine is a drug to relieve symptoms caused by urinary tract irritation, such as pain, burning, or the urge to urinate that occurs frequently or is unbearable. This medication only treats symptoms, but does not treat the cause of urinary tract irritation

Phenazopyridine is a pain reliever for the urinary tract. This drug works as a local anesthetic by soothing the irritated or inflamed urinary tract wall. Inflammatory conditions of the urinary tract wall are usually caused by infection, injury, surgery, or the use of a urinary catheter.
