Analysis of the Use of Over-the-Counter Therapy for the Prevention and Treatment of COVID-19

<i>Background and Objectives</i>: Self-medication includes the use of drugs or herbal preparations based on one's own discretion or the recommendation of another person, often a family member, friend, neighbor, or even a pharmacist, without prior examination and consultation with a doctor. The goal of this study was to determine respondents' reasons for using self-medication, determine the frequency of self-medication, and analyze differences in respondents' attitudes about self-medication in relation to several factors. <i>Materials and Methods</i>: The study was conducted as a cross-sectional observational study. The respondents were patients seeking medical examination at the Health Center in Jagodina who had used over-the-counter medications during the COVID-19 pandemic. A total of 175 respondents participated in the study. The study design provided answers to questions about the respondents' self-medication habits during the COVID-19 pandemic. <i>Results</i>: More than half of the respondents (53.71%) bought medicines without a prescription, with most cases involving analgesics (52.83%). Almost three-quarters of the respondents were completely vaccinated (74.29%) against COVID-19. Additionally, 39.62% of participants used vitamins as part of their self-medication during the COVID-19 pandemic. Among the vitamins, respondents most commonly used a combination of vitamins C and D (20.75%), vitamin D (5.66%), vitamin C (5.66%), and vitamin A (1.89%). <i>Conclusions</i>: Self-medication for the treatment of coronavirus is more often used by younger respondents, who are not yet married, do not have their own income, and rarely visit a doctor. As for supplements, respondents used zinc, and as for vitamins, respondents mostly used a combination of vitamins C and D.
