Re-Azo

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

Re-Azo is used to help with urinary symptoms like pain or burning, needing to urinate more often, and having a strong urge to urinate. These symptoms can come from infection, injury, surgery, a catheter, or other issues that irritate the bladder.

Re-Azo will help with urinary symptoms, but it will not treat a urinary tract infection. Make sure to take any antibiotic that your doctor prescribes to treat an infection.

Re-Azo 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 Re-Azo after meals.

Drink plenty of liquids while you are taking Re-Azo.

Re-Azo 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.

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

Do not use Re-Azo 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 Re-Azo.
