Drug-related problems and its associated factors among breast cancer patients at the University of Gondar Comprehensive Specialized Hospital, Ethiopia: A hospital-based retrospective cross-sectional study.

The prevalence of drug-related problems was high in our setting. Adverse drug reactions, the need for additional drug therapy, and non-adherence were the most frequently occurring drug-related problems in the study setting. Neoadjuvant chemotherapy and the presence of co-morbidities were significant predictors of drug-related problems among breast cancer patients.
