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.

You feel pain or burning when you urinate. 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.

In usual hypnotic dosages, the degree of respiratory depression produced is similar to that which occurs during physiologic sleep, while at higher dosages, the rate, depth and volume of respiration may be markedly decreased.
