Adverse drug reactions in patients taking anti tuberculosis therapy from directly observed treatment short course centre at Mandya Institute of Medical Sciences, Mandya: a cross sectional study

Abstract

Background: Ending the tuberculosis (TB) epidemic by 2030 is among the health targets of the sustainable development goals. Side effects to anti-TB drugs are common and may lead to reduced compliance to treatment. These adverse effects must be recognized early to reduce associated morbidity and mortality. Objective of this study was to determine the adverse drug reactions (ADR) to anti-tubercular therapy among patients visiting directly observed treatment, short-course (DOTS) centre MIMS, Mandya.Methods: A cross sectional study was conducted at DOTS Centre MIMS, Mandya. TB patients registered at DOTS Centre during the year 2018 were selected for the study. Verbal informed consent was taken from the TB patients and interviewed using pretested semi-structured questionnaire. Data analysis was done using descriptive statistics and chi square test.Results: Among the study population (n=90), 67 (74.4%) experienced ADR among which 47.7% took treatment for ADR and the remaining 52.3% patients were given reassurance. In this study, gastrointestinal manifestations (42.3%) were the most common adverse drug reaction (ADR). Of the TB patients who experienced ADR, 9.0% of them had interrupted ATT, however they completed full course of ATT.Conclusions: A considerable number of TB patients taking ATT experience ADRs and some of them may have to interrupt treatment. However, they need to be counselled or supervised with caution to complete their course of treatment to reduce the chances of treatment default and also reduce the occurrence of drug resistance.
