Which information will the nurse include when teaching the patient with a urinary tract infection (UTI) about the use of phenazopyridine?

A. Take phenazopyridine for at least 7 days: Phenazopyridine is a urinary analgesic and does not treat the underlying infection. It should be used only for symptom relief, usually for a short duration, and not as a substitute for the full course of antibiotics. B. Phenazopyridine may cause photosensitivity: Photosensitivity is not a commonly reported side effect of phenazopyridine. The primary concern with this medication relates to its effects on urine color rather than skin sensitivity to sunlight. C. Phenazopyridine may change the urine color: Phenazopyridine can turn urine a reddish-orange color, which is harmless but important for patients to understand to avoid alarm. Educating the patient about this expected effect improves adherence and reduces anxiety related to urine discoloration. D. Take phenazopyridine before sexual course: Phenazopyridine is not indicated as a preventative or prophylactic measure for sexual activity. Its use is for symptomatic relief of urinary discomfort and should be coordinated with the prescribed antibiotic regimen.
