Assessment of utilization pattern of fixed dose drug combinations in primary, secondary and tertiary healthcare centers in Nepal: a cross-sectional study.

FDCs were used extensively at different health care centers. The number of prescription in private centers, following established guidelines and the essential drug list (EDL), was much lower. The cost associated with the utilization of FDCs was higher in private sectors compared to public health care centers. In certain cases, the use of FDCs was questionable, and this study found a low use of essential medicines. Education to improve prescription practices at different healthcare levels is recommended.
