A nurse is caring for a client receiving phenazopyridine (Azo) for urinary tract analgesia. Which of the following side effects is associated with phenazopyridine?

Choice A reason: Vomiting is not a commonly associated side effect of phenazopyridine. While gastrointestinal upset can occur with many medications, it is not a specific or predominant side effect of phenazopyridine. Therefore, it is not the primary concern for patients taking this medication. Choice B reason: Dizziness can be a side effect of many medications, but it is not a characteristic side effect of phenazopyridine. Phenazopyridine is primarily used for its analgesic properties in the urinary tract, and dizziness is not commonly reported in relation to this drug. Focusing on more relevant side effects is crucial for patient education. Choice C reason: Orange-colored urine is a well-known and harmless side effect of phenazopyridine. This medication is used to relieve pain, burning, and discomfort in the urinary tract, and one of its notable effects is the discoloration of urine. Patients should be informed about this expected side effect to prevent unnecessary concern and ensure adherence to the medication regimen. Choice D reason: An increase in blood pressure is not typically associated with phenazopyridine. This medication does not significantly impact blood pressure regulation. Therefore, patients taking phenazopyridine do not need to be particularly concerned about hypertensive effects as a direct consequence of the medication.
