Purpose To determine whether desirable diabetes control is associated with polypharmacy and to evaluate potential drug interactions (DI) in participants with diabetes mellitus in the Brazilian Longitudinal Study on Adult Health (ELSA‐Brasil). Methods This cross‐sectional study included 1418 participants with medical diagnosis of diabetes at study baseline (2008–2010). Polypharmacy was defined as the use of ≥5 drugs. We described the frequency of the most common pharmacological groups used by patients and the potential DI.The association between desirable diabetes control (normal A1c, blood pressure and lipid levels) and polypharmacy was investigated using logistic regression. Results Most participants were men (52.5%), mean age 57.6 (SD 8.4) years, educated to the university level (39.4%), and self‐reported as white (42.9%). In this study, 7.1% (n = 101) of participants had desirable control of diabetes, while 40.4% (n = 573) used polypharmacy, and this use was not significantly associated with better diabetes control (adjusted odds ratio (OR = 1.35 [95%CI 0.86–2.13] P = .19).The pharmacological groups most frequently used were oral antidiabetics followed by acetylsalicylic acid, angiotensin‐converting enzyme inhibitors (ACE inhibitors) and statins.The prevalence of potentially mild, moderate and severe DI were, respectively, 2.5%, 14.7% and 0.9%; however, in the desirable control of DM group, these potential DI were related to comorbidity control. Conclusion Faced with the importance of achieving optimal control of diabetes and minimizing risks of potential DI, these results, which are in keeping with previous findings described in the literature, might indicate that guidelines for the patient‐centered management of control of diabetes must be revised.
