Background and Objectives Elderly are more likely to have potentially serious Drug-Drug Interactions (DDIs). The objective of the study was to identify the frequency of potentially serious drug interactions in the population of elderly treated at a Peruvian referral hospital, as well as their associated factors. Materials and Methods Analytical cross-sectional study in a population attended in the outpatient clinic of geriatrics at the Hospital Naval Medical Center during November 2018 - March 2019. The data recorded in the medical records were recorded and the presence of DDIs was evaluated using the Lexicomp®️ tool. The association with the potential factors was evaluated using a Poisson regression model with robust variances. Results We analyzed 306 clinical histories. The average age of 74 (68-82) years with male predominance (63,40%). 27,78% of the population had potentially serious drug interactions. Likewise, 61,76% consumed 5 to more drugs. 97,06% presented multimorbidity and 56,21% had arterial hypertension. In the bivariate analysis, the factors significantly associated with the potentially serious pharmacological interactions were the female gender (PR:0,65; CI:0,45-0,93; p=0,018), the presence of osteoarthritis (PR:1,82; CI:1,28-2,56; P=0,001), depressive symptoms (PR:1,80; CI:1,14-2,87; p=0,012), and polypharmacy (PR:8,15; CI:3,66-18,11; p<0,001). In the multivariate analysis, the factors significantly associated with potentially serious DDI were polypharmacy (PR:8,05; CI:3,61-17,92; P<0,001) and osteoarthritis (PR:1,76; CI:1,29-2,40; p<0,001). Conclusions Polypharmacy is the main risk factor for the presence of serious DDIs. Possible drug interactions should be routinely evaluated in polymedicated geriatric patients.
