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.

Trimethoprim, specifically the trimethoprim component, can interfere with a serum methotrexate as determined by the competitive binding protein technique CBPA when dihydrofolate reductase is used as the binding protein. No interference occurs, however, if methotrexate is measured by RIA.

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.
