Final answer:
Phenazopyridine (Pyridium) treats symptoms of urinary tract irritation such as pain and urgency (Option C), specifically dysuria, which is associated with bacterial cystitis and other UTIs.
Step-by-step explanation:
Phenazopyridine (Pyridium) is a medication used to treat symptoms of urinary tract irritation, such as pain and urgency, which are often caused by conditions like bacterial cystitis.
This medication works as an analgesic to relieve the discomfort associated with urinary tract infections (UTIs).
Phenazopyridine specifically alleviates the painful symptoms including dysuria, which is burning or pain during urination, a common symptom of conditions like cystitis and other types of UTIs.
While phenazopyridine helps manage symptoms, it is not an antibiotic and does not treat the underlying infection; antibiotics are typically used for that purpose.
Hence, the correct answer is Option C.
