Phenazopyridine is a urinary analgesic used to relieve pain, burning, urgency, and discomfort caused by irritation of the lower urinary tract. It is commonly used to alleviate symptoms associated with urinary tract infections (UTIs) and other conditions affecting the bladder and urethra. Phenazopyridine works by exerting a local analgesic effect on the urinary tract lining but does not treat the underlying infection. It is known to cause a harmless orange or red discoloration of urine, which can stain clothing and contact lenses. This medication should only be used for short-term symptom relief and is typically taken for no more than two days when used alongside an antibiotic for UTIs.
