Public use of ChatGPT for medication information in Saudi Arabia: a cross-sectional study

A cross-sectional online survey was conducted among adults in Saudi Arabia to explore public use of ChatGPT for medication-related information. A validated, self-administered questionnaire was distributed through social media platforms and analyzed using descriptive statistics and binary logistic regression. Among 475 respondents, nearly two-thirds reported using ChatGPT to inquire about medication use, mechanisms of action, and side effects. About one-third modified their medication behavior, raising potential safety concerns. ChatGPT use was more common among older adults, individuals with diploma-level education, those who were employed, unemployed, or retired, and participants living in smaller households. In contrast, participants working in medical professions, those earning less than 8,000 SAR per month, and users of over-the-counter or herbal products were less likely to use ChatGPT. Speed, accessibility, and ease of use were key facilitators, whereas doubts about accuracy and preference for healthcare professionals remained barriers. The findings indicate growing reliance on ChatGPT for medication information and suggest the need for public education, AI literacy, and stronger regulatory oversight.
