Active involvement of patients in the management of their health has been suggested as a major means of curtailing medication errors. This study aimed to assess the steps taken by hypertensive patients in avoiding medication errors before, during and after clinic visits.A cross-sectional study was conducted in Enugu State University Teaching Hospital (ESUTH), Parklane, Enugu, Nigeria (June to August, 2016) using a standardized 35-item interviewer-administered questionnaire. The IBM SPSS Version 20.0 was utilized for statistical analysis with P < 0.05, considered statistically significant.A total of 200 questionnaires were completed and returned. Few (24.4%) of the respondents were taking non-prescribed medicines and most (61.5%) knew their names. Only 41.9% of the patients monitor their blood pressure very often. There was a statistical difference between the mean scores of steps to avoid medication errors after the clinic visit for the different occupations (F = 8.109; P < 0.001) and educational level (F = 6.182; P < 0.001).Patients that took necessary steps in avoiding medication errors before their clinic visits were likely to avoid errors at the clinic. Also, patients that avoided medication errors at the clinic were likely to avoid medication errors after the doctor's visit.
