Results: Of the 387 respondents; 52.97% of households owned unused and out -of -date medicines. The main reasons for owning these medicines were symptom improvement (70.8%) and adverse effects (13.18%). Only 12.7% of households had been made aware of the proper disposal of these drugs.5.9% of respondents were aware of drug take -back systems, but 4.4% had returned expired drugs to the pharmacy. The preferred method of disposal was to keep them at home until they expired (33.6%) and then burn them in the open air (41.3%).98.7% of respondents had a poor disposal practice. Conclusion: Knowledge and awareness of the proper disposal of unused and expired medicines were low in the Boma HZ.
