A client with cystitis receives a prescription for phenazopyridine. Which information should the nurse explain to the client about its therapeutic effect?

A) Calms spasm in the urinary tract: This statement is incorrect. Phenazopyridine primarily provides analgesic (pain-relieving) effects for the urinary tract but does not directly affect muscle spasms. B) Provides an analgesic effect for irritated bladder mucosa: This is the correct response. Phenazopyridine is a urinary tract analgesic that acts locally to relieve pain, burning, and discomfort caused by irritation of the bladder mucosa. It does not treat the underlying infection but helps alleviate symptoms. C) Eliminates urinary bacteria: This statement is incorrect. Phenazopyridine does not have antibacterial properties and does not eliminate urinary bacteria. Antibiotics are typically prescribed to treat urinary tract infections by targeting bacterial growth. D) Use the medication after voiding after sexual intercourse: This statement is incorrect. While voiding after sexual intercourse can help reduce the risk of urinary tract infections (UTIs), phenazopyridine is not specifically indicated for this purpose. It is used primarily for symptom relief in cases of cystitis or other urinary tract irritations.
