Indications et Utilisation

Phenazopyridine Hydrochloride is indicated for the symptomatic relief of pain, burning, urgency frequency, and other discomforts arising from irritation of the mucosa of the lower urinary tract caused by infection, trauma, surgery, endoscopic procedures, or the passage of sounds or catheters. The use of Phenazopyridine Hydrochloride for relief of symptoms should not delay definitive diagnosis and treatment of causative conditions. The drug should be used for symptomatic relief of pain and not as a substitute for specific surgery or antimicrobial therapy. Phenazopyridine Hydrochloride is compatible with antimicrobial therapy and can help relieve pain and discomfort during the interval before antimicrobial therapy controls the infection. Treatment of a urinary tract infection with Phenazopyridine Hydrochloride should not exceed 2 days. There is no evidence that the combined administration of Phenazopyridine Hydrochloride and an antimicrobial provides greater benefit than administration of the antimicrobial alone after 2 days. (See DOSAGE AND ADMINISTRATION.)
