Perspectives of the public on the consumption of unregistered health products in Malaysia

OBJECTIVE: Unregistered medications which are lacking regulation in terms of safety, efficacy and quality may cause unpredictable adverse drug reactions (ADRs) in consumers. Therefore, this study aimed to assess the public knowledge, attitude and practice of consuming and purchasing unregistered health products in Malaysia.

METHODS: A cross-sectional study involving members of the Malaysian public was carried out using the convenience sampling method. Descriptive statistics were used to summarise the socio-demographic characteristics of the respondents. Associations between knowledge items/scores and other items were assessed using Spearman's rank correlations and Cramer's V. Regression analyses were carried out to determine whether the socio-demographic characteristics of the respondents influenced knowledge and practice relating to unregistered medications.

KEY FINDINGS: A total of 649 respondents completed the questionnaire with the majority being female (66.1%), unmarried (66.5%), Malay (52.5%) and possessing a bachelor's degree (53.5%). The knowledge of the public surveyed regarding unregistered (unlicensed) medications was lacking, especially in being able to identify a registered health product in Malaysia and formally complaining if necessary. The respondents agreed that currently, there are insufficient laws and educational programmes to tackle the issue. The respondents exhibited good practice habits by purchasing their medications from healthcare professionals. Mean knowledge score was positively correlated to practice scores at rs  = 0.423 (P-value
