Phenazopyridine

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

Phenazopyridine is used to relieve urinary symptoms like pain or burning, needing to urinate more often, and having a strong urge to urinate. These symptoms can happen due to infection, injury, surgery, catheter use, or other conditions that irritate the bladder.

Phenazopyridine will help with urinary symptoms, but it will not treat a urinary tract infection. Take any antibiotic your doctor prescribes to treat an infection.

Phenazopyridine may also be used for reasons not mentioned in this medication guide.

Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Take phenazopyridine after meals.

Drink plenty of liquids while you are taking phenazopyridine.

Phenazopyridine will most likely darken the color of your urine to an orange or red color. This is a normal effect and is not harmful. Darkened urine may also cause stains to your underwear that may be permanent.

Phenazopyridine can also permanently stain soft contact lenses, and you should not wear them while taking this medicine.

Do not use phenazopyridine for longer than 2 days unless your doctor has told you to.

This medication can cause unusual results with urine tests. Tell any doctor who treats you that you are using phenazopyridine.

Store at room temperature away from moisture and heat.

You should not use phenazopyridine if you have kidney disease.

You should not use phenazopyridine if you are allergic to it, or if you have kidney disease.

To ensure phenazopyridine is safe for you, inform your doctor if you have:
