Pharmacists supply phenazopyridine as a capsule or tablet, according to MedlinePlus. Patients should swallow the medication whole and not crush it.

Phenazopyridine changes the color of the urine to a reddish orange, explains Mayo Clinic. Patients should contact their medical care provider if they experience blood in the urine or their pain becomes worse. They should also call their doctor if there is a sudden decrease in urine output while taking this medication. The dye in the medication sometimes stains contact lenses. This medication also affects the results of some medical tests, including those for urine sugar.
