Generic medications are cost-effective without compromising therapeutic outcomes. Therefore, the goal of this study was to investigate, using a cross-sectional study design, the factors influencing Saudi Arabian consumers' preferences between innovator and generic medications. This cross-sectional study was carried out in Saudi Arabia using a Google survey form. For data collection, a simple random sampling strategy was used. The recruited participants were surveyed using a validated questionnaire that focused on six influencing domains: physician, pharmacist, perceived effectiveness, price, information availability, and confidence based on prior experience. The obtained data was used to analyze factors that have an association with any of the six domains using multinomial regression analysis. A correlation analysis was performed to examine the relationship between domains. The 317 participants included 64.4 % females, 52 % aged ≥ 26, and a large proportion of Saudi nationals (82.6 %) and university graduates (78.9 %). Being employed (OR:3.029; P = 0.006; CI: 6.715–1.366), a healthcare providers (OR:2.298; P = 0.043; CI: 5.151–1.025), and having insurance coverage (OR:1.908; P = 0.017; CI: 3.245–1.122) had a greater influence on medication selection. Participants with linguistic and business educational backgrounds (OR:3.443; P = 0.022; CI: 9.950–1.191), those living in the northern region of Saudi Arabia (OR:3.174; P = 0.009; CI: 7.585–1.328), having chronic ailments (OR:3.863; P = 0.013; CI: 11.274–1.324), and possess insurance (OR:1.748; P = 0.039; CI: 2.971–1.028) get readily influenced by pharmacist. People who were married and lived in Saudi Arabia's southern region were influenced by perceived effectiveness when choosing medicine. Participants from the northern region were found to be influenced by the price of the medicines, information about the medicines, and confidence based on previous experience. The price of medicines has a significant impact on those suffering from chronic diseases. At a significant level of P = 0.01, all six influencing domains were found to be positively correlated with each other. The study shows that healthcare providers, drug prices, perceived efficacy, and information availability all have a big influence on the Saudi Arabian population's choice of medications.Educational background, location, and chronic disease status are associated with several influencing domains. Aside from public awareness campaigns, healthcare p
