What is the role of phenazopyridine in UTI treatment?

Phenazopyridine is primarily used as a urinary analgesic, meaning it provides relief from pain, burning, and discomfort associated with urinary tract infections (UTIs). It works by exerting a local anesthetic effect on the lining of the urinary tract, which helps alleviate the painful symptoms that patients often experience during a UTI.

Although phenazopyridine can make a significant difference in a patient's comfort level, it does not have any antibacterial properties and therefore does not treat the underlying infection. Antibiotics are the medications that target and eliminate the bacteria causing the UTI. Additionally, the substance does not play a role in preventing kidney stone formation or acting as a diuretic, making its primary function as an analgesic distinct and essential for symptom relief during UTI treatment.
