The aim of the study was to evaluate the use of potentially inappropriatemedications (PIM) among elderly in Viçosa (MG), according to the Beers criteria 2012 and the STOPP criteria, as well as identifying the factors associated with this use. It is a cross-sectional study conducted in 2009 with 621 not institutionalized elderly, which were addressed through household interviews. The explanatory variables were gender, age, education, perception of health, activity restrictions in the last 15 days, functional capacity, history of hospital admission, number of selfreporteddiseases and polypharmacy. Descriptive analysis and Poisson regression univariate and multivariate analysis were held. According to Beers criteria 2012, 47.9% of the elderly were exposed to at least one PIM (CI 95% = 43.7% - 52.1%). Already according to STOPP criteria, the prevalence of use of PIM was 48.9% (CI 95% = 44.7% -53.0%). Considering both criteria, 33.7% of elderly used PIM. However, regardless of the criteria, a total of 61.9% of the subjects used PIM. Inmultivariate analysis the polypharmacy remained independently associated with the use of PIM according to the Beers criteria. It is important to qualify polypharmacy so that it does not constitute a risk factor for the use of MPI. It is important to qualify the polypharmacy so that it does not constitute a risk factor for the use of MPI. As for the STOPP criteria, the variables independently associated with the use of PIM werefemales, the perception of regular health and polypharmacy. The use of STOPP and Beers criteria revealed a high prevalence of use of PIM among the elderly and there was no significant difference between them. Our results demonstrate that both criteria are applicable to the reality of primary care in Brazil. Such criteria shall be disseminated and incorporated into professional practice through clinical protocolsaimed at the health care of the elderly. Additionally periodic update is required so that they can adapt to changes of marketed medications and the current scientific evidence.
