Spectrum of Adverse Effects and it’s Associations in Patient Medicated with Anti-Tubercular Drugs

Abstract BackgroundEvidence suggests that adverse drug effects (ADRs) from long-term therapeutic intervention in tuberculosis are obvious; however, were taken insouciantly due to the only therapeutic alternative. Hence, this study was undertaken to characterize the adverse effects and its association among patients medicated with anti-tubercular drugs.MethodsA longitudinal prospective study was conducted among the patient medicated with anti-tubercular drugs. As per the guideline of Nepal’s National tuberculosis control program (NTP);the treatment category was selected, fixed-dose-regimen was calculated, and the treatment outcome was affirmed. Patients’ demographics and other clinical details were extracted from the repository files and via a pre-tested questionnaire. Upon a consecutive follow-up, observed adverse effects were noted and multivariate logistic analysis against independent factors was done for elucidating any association.ResultsOf 177 cases enrolled, 138(77.9%) reported at least two adverse effects. In our multivariate logistic analysis: female, abnormal body mass index (BMI) i.e. underweight and overweight cases, patients’ behaviors i.e. smoking/drinking or both, clinically diagnosed cases, and intensive treatment phase were independently associated with adverse side effects. Loss of appetite (85.4%) was the commonest while dermatologic manifestations (1.2%) and severe weight-loss (1.2%) were the least observed side-effects among the patient medicated with anti-tubercular drugs.ConclusionsAdverse effects of anti-tubercular therapy are associated with patients’ demographics variables, study settings, treatment phase, and treatment categories. For the clinical management, the symptomatic treatment, regular follow-up after implicated therapy, and temporary therapeutic-discontinuation may be required.
