To address this knowledge gap, we conducted a study to evaluate the consumer use of an OTC urinary analgesic, phenazopyridine pyridium that is recently widely marketed. We chose to study phenazopyridine because urinary tract infection UTI is a common health condition and there is abundant direct-to-consumer advertisement of OTC phenazopyridine found in television commercials and women's magazines. In addition, the standard of treatment for UTI and the use indications for phenazopyridine are well described in current medical literature, thus allowing us to derive explicit criteria for appropriateness of use. In our study, we measured the rates of inappropriate use in 31 community pharmacies within the Los Angeles area and investigated factors that might be correlated with consumers using this drug inappropriately or substituting it for provider care.

This category implies possible clinical applicability in body sites where the drug is physiologically concentrated or in situations where high dosage of drug can be used. This category also provides a buffer zone which prevents small uncontrolled technical factors from causing major discrepancies in interpretation.

This study has some limitations. 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.

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.

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.

Barbiturate therapy should be withdrawn promptly at the first sign of a dermatologic adverse effect. However, cutaneous reactions may proceed to an irreversible stage even after cessation of medication due to the slow rate of metabolism and excretion of barbiturates. Patients should be advised to promptly report signs that may indicate impending development of barbiturate-related cutaneous lesions, including high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis.

Peak blood concentrations for individual components trimethoprim and sulfamethoxazole occur 1 to 4 hours after oral administration.

However, patients with severely impaired function exhibit an increase in the half-lives of both components, requiring dosage adjustment see section. Detectable amounts of trimethoprim and sulfamethoxazole are present in the blood 24 hours after drug administration.
