Warnings phenazopyridine hydrochloride is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity in experimental animals (iarc 1980, 1982, 1987, nci 1978). when administered in the diet, phenazopyridine hydrochloride increased the incidences of hepatocellular adenomas and carcinomas in female mice and adenomas and adenocarcinomas of the colon and rectum in rats of both sexes. there is inadequate evidence for the carcinogenicity of phenazopyridine hydrochloride in humans (tarc 1987). in one limited epidemiological study, no significant excess of any cancer was observed among 2,214 patients who received phenazopyridine hydrochloride and were followed for a minimum of 3 years.

General the patient should be advised that phenazopyridine produces an orange to red color in the urine and feces, and may cause staining. phenazopyridine may cause discoloration of body fluids and staining of contact lenses has been reported. a yellowish color of the skin or sclera may indicate accumulation of phenazopyridine resulting from impaired renal function and necessitates discontinuance of the drug. it should be noted that a decline in renal function is common in elderly patients. phenazopyridine may mask pathological conditions and interfere with laboratory test values using colorimetric, spectrophotometric or fluorometric analysis methods. cautious use in patients with g-6-pd deficiency is advised since these patients are susceptible to oxidative hemolysis and may have greater potential to develop hemolytic anemia.

Dosage and administration 100 mg tablets: average adult dosage is two tablets 3 times a day after meals. 200 mg tablets: average adult dosage is one tablet 3 times a day after meals. when used concomitantly with an antibacterial agent for the treatment of a urinary tract infection, the administration of phenazopyridine hydrochloride should not exceed 2 days.

Adverse reactions the following adverse events have been reported: cns: headache. gastrointestinal: nausea, vomiting and diarrhea. dermatologic and hypersensitivity: rash, pruritus, discoloration, anaphylactoid-like reaction and hypersensitivity hepatitis. hematologic: methemoglobinemia, hemolytic anemia, potential hemolytic agent in g-6-pd deficiency, sulfhemoglobinemia. other: visual disturbances, renal and hepatic toxicity usually associated with overdose, renal calculi, jaundice, discoloration of body fluids and aseptic meningitis.

Drug interactions the interaction of phenazopyridine with other drugs has not been studied in a systematic manner. however, the medical literature to date suggests that no significant interactions have been reported.

Pregnancy category b reproductive studies with phenazopyridine (in combination with sulfacytine) in rats given up to 110 mg/kg/day and in rabbits given up to 39 mg/kg/day during organogenesis revealed no evidence of harm to offspring. one prospective study in humans demonstrated that phenazopyridine traverses the placenta into the fetal compartment. there are no adequate and well-controlled studies in pregnant women. therefore, phenazopyridine should be used in pregnant women only if the benefit clearly outweighs the risk.

Children adequate and well-controlled studies have not been performed in the pediatric population. no pediatric-specific problems have been documented.

Clinical pharmacology phenazopyridine hydrochloride is excreted in the urine where it exerts a topical analgesic effect on the mucosa of the urinary tract. this action helps to relieve pain, burning, urgency and frequency. the precise mechanism of action is unknown. pharmacokinetics the pharmacokinetic properties of phenazopyridine hydrochloride have not been determined. phenazopyridine and its metabolites are rapidly excreted by the kidneys. in a small number of healthy subjects, 90% of a 600 mg/day oral dose of phenazopyridine hydrochloride was eliminated in the urine in 24 hours, 41% as unchanged drug and 49% as metabolites.

Carcinogenesis, mutagenesis, impairment of fertility long-term administration of phenazopyridine has been associated with tumors of the large intestine in rats and of the liver in mice. available epidemiological data are insufficient to evaluate the carcinogenicity of phenazopyridine in humans. in vitro studies indicate that phenazopyridine in the presence of metabolic activation is mutagenic in bacteria and mutagenic and clastogenic in mammalian cells.
