“…The study revealed that a majority of homesteads in the urban areas dispose their pharmaceuticals in waste bins together with general solid waste that is periodically collected and disposed in landfills and dump sites by the local municipal authority. This findings confirms earlier reports that described methods of disposal at global level as garbage, toilet or sink [40]. A recent study conducted among the public in Lagos State, Nigeria reported that 73.2% of respondents disposed their unused medicines in garbage [41], while our study reported 54%, probably because our study participants included rural households.…”

The dramatic increase in chemical production and trade during the past three decades has raised both public and official concern about the potential risks posed by hazardous chemicals pesticides and medicines. With increased threat from HIV infection, many householders find themselves needing to access and keep a complex and diverse variety of pharmaceuticals. A cross-sectional, explorative and qualitative survey was carried out among 329 households involving in-depth interviews and observation to investigate types of pharmaceuticals found in rural, peri-urban and urban areas in Eswatini, the level of knowledge of householders and disposal practices of unused and expired pharmaceuticals. Eswatini does not have any laws that regulate the management of household pharmaceuticals. The results of the survey suggested that a majority of homesteads (85%) stored unused, often expired and left-over pharmaceuticals mainly for future use. The level of knowledge of risks associated with presence of pharmaceuticals was found to be very low among householders and that no programmes were initiated by the local health authority or the municipal councils to enhance the knowledge levels. Eighty-two different types of pharmaceuticals were identified including analgesics (38%), antibiotics (27%), supplements (21%) and others (14%). In urban areas, respondents reported that they disposed waste pharmaceuticals into the normal bins which are collected and disposed into landfills and dump sites while peri-urban and rural areas reported that they burn their pharmaceuticals in backyards. The findings in this study suggest the need for further research to determine availability of the variety of pharmaceuticals in surface, ground and drinking water around the country. Guidelines for management and safe disposal of pharmaceuticals need to be urgently developed and programmes to educate householders should be initiated in Eswatini.

“…The researcher assessed participant behavior concerning the disposal of drug options and understanding of drugs and investigated participants' attitudes and endorsements about unused drug disposal practices as in previous studies (2,10,11) . This study specifies that there is a need for proper education or awareness in patients to create awareness regarding the disposal methods of unused medicines and expired drugs safely (12)(13)(14)(15) . Later followed the practices after the awareness program was conducted in the study which resulted in a 51.4% increase in awareness and proper disposal and storage based on the number of unused medications in the households which resembles previous studies (3,16,17) .…”

Objectives: To determine the way of drug disposal and storage practices carried out in society and create awareness about the drug is to be disposed of properly to avoid chemical and physical issues by the pharmaceuticals. To evaluate the way of drug disposal and storage practices are carried out in society after the awareness program. Materials and methods : This study was carried out by community-based cross-sectional study design using ICF and KAP Forms. A study was conducted on 1004 households in the South Indian district to analyze the drug disposal and storage practices followed in the households before the awareness program. Data processed and analyzed through Statistical methods in the Epi info data Version:7.2.5.0 and Microsoft Excel 2019 Version: 1808. Findings: Though disposal was the main aspect, improvements in the storage conditions of the drug dosage forms were found in the study, where 93.72% of the population followed proper storage practices. The result data revealed that practices followed after the awareness program which was conducted in the study resulted in 75.89% of participants not having unused medicines after awareness and proper disposal and storage. Novelty: Creating awareness about methods of drug disposal and storage reduces the risk of accidental poisoning from medicine and its contamination as many of unaware of its complications. This study achieved to increase in the proper drug disposal and storage practices among household participants.

“…Welleducated pharmacists can contribute significantly to reducing the improper disposal of medications. Moreover, in Nigeria, most previous studies on the inappropriate disposal of unused medication have focused on general populations [22,23], with limited information on healthcare students.…”

Background The safe disposal of unused medication is a critical public health issue, with risks including environmental pollution, accidental ingestion, and misuse. Inadequate adherence to proper disposal methods among healthcare students could affect the practice of safe disposal of unused medicines as future healthcare professionals. This study, conducted at a Nigerian university, aimed to assess the knowledge, adherence to safe disposal practices, and barriers faced by healthcare professional students regarding unused medication disposal. Methods A cross-sectional study was carried out among 930 healthcare students in a Nigerian University, comprising medical and surgery, nursing, pharmacy, physiotherapy, and medical laboratory science students. Information was gathered from respondents using a self-administered questionnaire. Multivariate analyses were used to evaluate the relationship between specific variables and participants’ knowledge and practice scores, while chi-square and logistic regression tests were used for categorical variables at p < 0.05. Results A total of 930 students participated in this study. The results revealed a significant gap in knowledge, with (67.7%; 630) of the participants unaware of proper disposal methods and most scoring either 0 (31.9%; 297) or 1 (46.0%; 428) out of 4 on a knowledge-based questionnaire. Pharmacy students were the most knowledgeable, with 44.4% falling into the high knowledge category. However, their knowledge did not always correspond to correct practices, with only (10.1%; 94) of participants reporting use of recommended disposal methods such as returning unused medicine to a pharmacy or a drug take-back program. Significant associations were found with course of study (χ²=12.14, p = 0.033) and awareness of correct disposal methods (χ²=4.035, p = 0.045). Those aware of the correct disposal method had a higher odds ratio of high knowledge score (OR = 1.62, 95% CI: 1.1–2.41, p = 0.018) compared to those who were not aware. In terms of disposal practices, those who had received training on safe disposal had significantly higher odds of good practice score (OR = 2.25, 95% CI: 1.36–3.74, p = 0.002). Major barriers identified included lack of access to drug take-back programs (50.4%; 469), lack of knowledge (36.8%; 342), and inconvenience (10.3%; 14). Conclusion A knowledge gap was revealed among the respondents regarding the safe disposal of unused medications. Despite the presence of knowledge and awareness, these do not necessarily translate into good disposal practices. This call for strategies to overcome identified barriers, with the aim to bridge the knowledge-practice gap and promote safe disposal of unused medication. The study underscores the urgent need for improved public health policies and educational programs on safe medication disposal.
