A patient who has pain with urination associated with cystitis will be discharged home with a prescription for phenazopyridine (Pyridium). What instruction will the nurse include when teaching the patient about this drug?

A. "Report reddish-brown urine to the provider immediately.": Phenazopyridine commonly causes reddish-orange urine because of its dye component. This effect is harmless and expected, so reporting it as an emergency is unnecessary. Teaching focuses on reassuring the patient about this normal discoloration. B. "The drug provides symptomatic relief of pain.": Phenazopyridine is a urinary analgesic that helps reduce dysuria, burning, and urinary discomfort. It does not treat the infection itself but offers comfort while antibiotics work, making this the correct teaching point. C. "Do not take this drug concurrently with an antibiotic.": Phenazopyridine is safely used along with antibiotics to relieve symptoms until the infection is controlled. Avoiding concurrent use would delay comfort without clinical benefit. D. "This drug has antiseptic and analgesic properties.": Phenazopyridine does not have antiseptic or antimicrobial action. It does not eliminate bacteria and plays no role in infection control, only symptom relief.
