Additional Information

Why is this medication prescribed

Phenazopyridine relieves urinary tract pain, burning, irritation, and discomfort, as well as urgent and frequent urination caused by urinary tract infections, surgery, injury, or examination procedures. However, phenazopyridine is not an antibiotic; it does not cure infections.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

What other information should I know

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to phenazopyridine.

Phenazopyridine can interfere with laboratory tests, including urine tests for glucose (sugar) and ketones. If you have diabetes, you should use Clinitest rather than Tes-Tape or Clinistix to test your urine for sugar. Urine tests for ketones (Acetest and Ketostix) may give false results. Before you have any tests, tell the laboratory personnel and doctor that you take this medication.

Phenazopyridine stains clothing and contact lenses. Avoid wearing contact lenses while taking this medicine.

Do not let anyone else take your medication. Your prescription is probably not refillable.

If you still have symptoms after you finish the phenazopyridine, call your doctor.
