Adverse Drug Reaction and Its Predictors Among Psychiatric Patients Taking Psychotropic Medications at the Mizan-Tepi University Teaching Hospital

INTRODUCTION: Psychotropic medications are crucial in the treatment of a variety of psychiatric disorders. Use of second-generation antipsychotics (SGA) has been associated with many adverse events. Assessment and monitoring of ADRs is required to develop appropriate interventional strategies to manage, prevent and minimize the risks of undesirable effects and thus improve quality of life and adherence, avoid relapse, and reduce treatment costs. OBJECTIVE: The objectives of this study were to assess adverse drug reactions and its predictors in psychiatric patients taking psychotropic medications from the outpatient pharmacy of MTUTH. METHODS: A cross-sectional study design was conducted using a structured questionnaire interviewing a psychiatric patient. One way ANOVA and bivariate logistic regression was computed for all independent variables to identify variables that fit for multivariate logistic regression. A p-value less than 0.05 was considered significant. RESULTS AND DISCUSSIONS: A total of 101 patients (91.8%) experienced one or more types of ADR in the current study. There was a statistically significant relationship between ADRs management and age, marital status, educational status, occupation, and monthly income of the study participants. The odds of having experienced autonomic adverse drug reactions experience among respondents aged 30 years and older higher than those under 30 years. Participants taking multiple medications were more likely to face psychiatric adverse drug reactions compared to those taking a single medication. Patients taking multiple psychotropic medications were ten times more likely to develop autonomic adverse drug reactions compared to those taking a single drug. CONCLUSION: The study revealed a moderate incidence of ADR in patients attending the psychiatric OPD. Age and number of antipsychotics were predictors of ADR (autonomic and psychiatric). This study revealed that there is a gap in the role of clinicians in the monitoring and reporting of ADRs.
