Our study suggests one approach for reducing inappropriate use of OTC phenazopyridine. Among the various factors, knowledge about the drug is a mutable one. Individuals who had correct knowledge about phenazopyridine's analgesic effects were less likely to inappropriately use it and substitute it for medical care, even when we controlled for previous use of prescription phenazopyridine and history of UTI. However, correct knowledge has only a moderate effect on decreasing inappropriate use and substitution behaviors. Even if all consumers had correct knowledge about phenazopyridine, there would still be substantial inappropriate use and substitution. Thus, increasing knowledge alone cannot provide a complete solution. Further studies are needed to determine if this drug should continue to be available over the counter, and if so, ways to ensure proper consumer usage.
