Treatment with Warfarin reduces the blood coagulation capacity, being followed up by the International Normalized Ratio (INR) blood tests. Socioeconomics and cultural factors and the therapeutics may influence the test results. Objective of the study was to characterize patients using Warfarin and to identify factors that contribute to the INR to stay out of the therapeutics range (2,0 to 3,0).Descriptive and exploratory method was applied by means of data acquisition, taking into consideration the following variables: patient profile, use of Warfarina and its administration form, food habits, physical activities and blood control (IRN).The sample, had 38 patients using Warfarin for 30 days and presenting blood test out of the therapeutic range. Patients under study showed inadequate food habits, drug interaction (Warfarin with antibiotics and antiarritmics) and poor adhesion to the treatment.
