This study examines consumer knowledge regarding the urinary tract analgesic phenazopyridine, which recently became available without prescription. METHOD We conducted a cross-sectional survey of a stratified cluster random sample of purchasers of OTC phenazopyridine (N = 434) in 31 Los Angeles retail pharmacies. RESULTS The response rate was 58\%. Only 29\% correctly characterized the likely cause of their symptoms, and only 57\% correctly characterized the action of the drug. Worse consumer knowledge was associated with nonwhite race, first-time use, and less contact with health providers. CONCLUSION Many consumers possess poor knowledge about phenazopyridine, potentially leading to undertreatment, especially in groups with worse access to care.}, issn = {1544-1709}, URL = {https://www.annfammed.org/content/2/3/240}, eprint = {https://www.annfammed.org/content/2/3/240.full.pdf}, journal = {The Annals of Family Medicine} }
