The aims of this study were to investigate the prevalence and to describe the most frequent potential interactions between antidepressants and antihypertensive and glucose lowering drugs in the HIPERDIA Program at two primary care units in Coronel Fabriciano, Minas Gerais State, Brazil. Data were collected through the patient registry in the HIPERDIA Program and the local psychoactive drug dispensing system. Interactions were classified as due to pharmacokinetic and/or pharmacodynamic mechanisms. Prevalence of antidepressant use in the HIPERDIA Program was 4.37% (29 of patient 663 records). Of the HIPERDIA patients in treatment with antidepressants, 19 were exposed to 47 interactions, 23.4% of which involving pharmacokinetic, 61.7% pharmacodynamic synergy, and 15.9% simultaneous pharmacokinetic and pharmacodynamic mechanisms. Complications can arise from drug-drug interactions, a situation that can escape the attention of prescribing health professionals.
