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.

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.

A report of "Intermediate" indicates that the result should be considered equivocal, and, if the microorganism is not fully susceptible to alternative, clinically feasible drugs, the test should be repeated. 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. A report of "Resistant" indicates that the pathogen is not likely to be inhibited if the antimicrobial compound in the blood reaches the concentrations usually achievable; other should be selected. Missing data, found in only 3 surveys, were imputed to be the mean. Zero order correlation matrices were used as an initial check for multicollinearity.

Substitution. Consumers' substitution of phenazopyridine for provider care was based on self-reported intentions at the time of purchase. Although our questionnaire measured anticipated use and intended substitution, it is commonly accepted in the research literature that intention is strongly linked to direct action. This survey of OTC phenazopyridine consumers in 31 Los Angeles County pharmacies showed that over half were using this medication inappropriately and that more than a third were substituting it for provider contact. Poor knowledge was an independent predictor of both inappropriate use and substitution for provider care, despite the fact that most consumers had adequate levels of education, income, and private health insurance. buy novolog new zealand

It would be important to expand our methodology to examine these drugs as well. Currently, 2 of the criteria used by the FDA for approving OTC marketing include 1 low potential for misuse and abuse, and 2 labeling instructions that are understandable to the average consumer. While these preconversion criteria may demonstrate consumer safety information under simulated environments, they appear to be insufficient in the real-world setting to ensure proper consumer usage behavior. The high rates of inappropriate use and substitution that we found suggest a wide discrepancy between these intended guidelines and actual consumer usage patterns. Further research is needed to understand how consumers use OTC medications, and more guidelines are needed to ensure the safe distribution of OTC medications. Extensive resources devoted to public education on an ongoing basis and better post-OTC marketing surveillance may help ensure that these medications are used appropriately by the public. purchase tegretol in canada
