What is phenazopyridine?

Phenazopyridine is a pain reliever that affects the lower part of your urinary tract (bladder and urethra).

Phenazopyridine is used to treat pain, burning, increased urination, and increased urge to urinate. These symptoms are usually caused by infection, injury, surgery, catheter, or other conditions that irritate the lower urinary tract.

Phenazopyridine will treat the symptoms of a urinary tract infection, but this medication does not treat the actual infection. Take any antibiotic that your doctor prescribes to treat your infection.

Phenazopyridine may also be used for other purposes not listed in this medication guide.

If you have any of these conditions, you may need a dose adjustment or special tests to safely take phenazopyridine.
