New nerve endings grow and become hypersensitive so they can detect further contact and withdraw. vessels in the area shut down to prevent possible infection from traveling to the rest of the body. Finally, muscles go on the defensive, producing spasms in the pelvic floor which reduce flow and produce further inflammation.

The survey response rate was calculated as the number of surveys returned divided by the number of products sold during the study period.

First, due to the impracticality of collecting urine specimens in a community pharmacy setting, presumed UTI was based on the presence of the triad symptoms. Nevertheless, these classic triad symptoms have a proven high sensitivity for diagnosing UTI. Second, because we studied 1 medication purchased by consumers from a particular chain of retail pharmacies in 1 county, our results may not be generalizable to other regions, pharmacies, or health conditions. However, this limitation is somewhat offset by the fact that we studied a well-known pharmacy, a common health condition, and an ethnically diverse population. Third, because the study was cross-sectional and anonymous, we do not have follow-up with the respondents to determine whether their behaviors resulted in adverse outcomes such as pyelonephritis or other serious health conditions. Nevertheless, our data collection methods enabled us to overcome logistical problems that have hindered previous studies and to conduct the first consumer study of OTC drug use in community pharmacies. Stewart, director of the Stewart-Forbes Vulvovaginal Specialty Service at Harvard Vanguard Medical Associates in Boston. "There's only been interest in the last few years. Recently the National Institutes of Health NIH have taken an interest. These challenges are reflected in ongoing discussions between the FDA, health insurance companies, the pharmaceutical industry, consumers, and health care providers. Proponents of reclassification believe that switching prescription drugs to OTC status can lower drug costs, decrease health services utilization, and increase consumer access to self-care products. In contrast, critics of this process are concerned with improper self-diagnosis and self-medication, leading to misuse and adverse outcomes. This controversy is illustrated in the current debate on whether to reclassify prescription allergy medications and cholesterol-lowering agents.

Findings from this study have striking implications for the OTC treatment of urinary symptoms. The high rates of inappropriate use and substitution among the self-medicating population in this study suggest that UTIs often may be undertreated and that there may be delays in diagnosing or treating other mimicking conditions. While phenazopyridine is indicated for use in temporary or interim symptom relief pending further medical care, most of the consumers go beyond this indication and are using this drug as the only initial treatment for their urinary conditions without plans to seek further medical evaluation. And because phenazopyridine is an analgesic that can mask dysuria, consumers may have the false notion that their conditions are cured. On the contrary, the low rate of antibiotic use among those respondents with triad UTI symptoms who had visited providers may suggest problems with suboptimal care. Although this study was not designed to evaluate the quality of care delivered by providers, our findings suggest that some investigation is warranted.
