What is phenazopyridine-oral, and how does it work (mechanism of action)?

Phenazopyridine is an oral urinary analgesic (pain relieving medication). It is available over-the-counter (without a prescription or OTC) in lower strengths, and with a prescription for higher strengths. It is used commonly to treat symptoms of pain, burning, urgency, frequency, and other symptoms associated with lower urinary tract infections (UTIs).

Although the exact mechanism of action is unknown, phenazopyridine is thought to provide relief of symptoms of UTIs by acting as a local anesthetic on the lining of the urinary tract. Phenazopyridine is excreted in the urine and may cause urine to change to an orange or red color. Phenazopyridine does not have any antibacterial action and should not be used to treat UTIs. It is only used to provide relief of symptoms associated with UTIs.
