Adverse drug reactions and contributing factors in patients with drug-resistant tuberculosis: A 7-year retrospective cohort study in Addis Ababa, Ethiopia

In this study involving patients with drug resistant tuberculosis, over half of the participants encountered at least one adverse drug reactions. Patient admission, baseline anemia, and older age were identified as major factors associated with adverse drug reaction during multidrug resistant tuberculosis treatment. Particular emphasis should be placed on these susceptible groups to facilitate early prediction, prompt management, and the formulation of appropriate treatment regimens that address adverse drug reactions effectively.
