Self-medication practices among university students at a public university in Riyadh, Saudi Arabia

Self-medication is a concern at the global level. It comes with complications and different health issues. This study measures the prevalence, influential factors, and reasons behind self-medication.

A descriptive cross-sectional study was conducted at Imam Mohammad Ibn Saud Islamic University. The prevalence and influential factors were measured between September and November 2023. Statistical analysis was performed using RStudio (R version 4.3.1). We used frequencies and percentages to present categorical variables. Using a convenient sampling technique. Factors associated with using self-medication and the differences between students of the medical college and their non-medical counterparts were assessed using Pearson's Chi-squared test or Fisher's exact test. Statistical significance was considered at P < 0.05.

We initially received 410 responses on the online platform. However, we excluded seven responses from those who disagreed to participate and 12 from participants outside Riyadh. The majority of the participants were female (67.5%). Three hundred nineteen (319) participants indicated that they had ever used self-medications, accounting for a prevalence of 81.6%. Regarding the reasons for self-medication, the most frequently cited factors were 'previous experience' (66.5%) and 'time-saving' (50.2%). Additionally, the primary source of drug information utilized for self-medication practices was predominantly from 'relatives/friends' (62.4%) and 'pharmacologists' (48.0%). Medications were primarily used for headache (76.8%), fever (48.6%), and pain (47.3%). The most commonly used classes of drugs used for self-medication were painkillers (84.0%), vitamins (42.0%), and eye drops (32.9%).

The results showed that the prevalence of self-medication is high in the surveyed population. There has been an association between monthly income and the prevalence of self-medication. As pharmacists are the second most common source of drug information, it is essential to increase responsibility and avoid marketing and personal benefiting behavior as they are considered a reliable source of information in the population. Healthcare organizers can utilize our study to educate people about the adverse effects of self-medication.
