Over-the-Counter (OTC) medicines and food supplements plays an important role in healthcare. It is generally accepted that, when used properly, OTC medicines save consumers time and money. In this paper we looked into the purchasing behavior of the Hungarian population regarding OTC drugs and food supplements, highlighting the significance of self-medication. Using a quantitative online survey in March 2022 with a national representative sample, the research aimed to measure the out-of-pocket health expenditures, focusing on OTC drugs and food supplements. The analysis showed that the population spends more money on OTC drugs and food supplements than the co-payment of prescription (Rx) drugs, and the combined expenditures on OTC drugs and food supplements significantly contribute to the household's total healthcare costs, representing 45% of this budget. Three hypotheses were formulated to investigate the relationships between the spending on Rx medications, OTC drugs, food supplements, and various demographic factors. The analysis showed significant correlations, indicating that as expenditures on Rx medications increase, so do the purchases of OTC drugs and food supplements. Demographic analysis indicated that the younger demographic age group (18-35 years) tends to spend the least on both Rx, OTC drugs and food supplements, while the 36-50 age group exhibits the highest expenditure on food supplements. However, no significant difference in OTC drug purchases was found among those older than 36 years. The study raises further questions regarding the purchasing behavior of chronic patients, the differentiation between OTC drugs and food supplements by consumers, the influence of minors in the household on purchasing decisions, and whether the primary target demographic for these products should be expanded beyond the 35-50 aged women as it is defined nowadays.
