Phenazopyridine

Phenazopyridine 100mg
Phenazopyridine is a urinary analgesic that provides relief from pain, burning, and discomfort associated with urinary tract infections (UTIs) and other urinary tract irritations. It works by exerting a soothing effect on the lining of the urinary tract, helping to alleviate symptoms such as urgency and frequency of urination. While it effectively eases symptoms, Phenazopyridine does not treat the underlying infection and is often used in conjunction with antibiotics for comprehensive UTI management.
