Influence of Medical Education on Medicine Use and Self-Medication Among Medical Students: A Cross-Sectional Study from Kabul.

Objective: To compare the prevalence of self-medication among first- and fifth-year medical students at Kabul University of Medical Sciences. Methods: A cross-sectional study was conducted with the participation of all first- and fifth-year medical students by using a short, self-administered questionnaire. The prevalence of self-medication was estimated in the entire study population and also in those who had used medicines in the preceding one week. Results: Of the total 302 students, the prevalence of medicine use was 38%. The prevalence of self-medication in all study population was 25.16%, whereas in those who had used medicines was 64.9%. Prescription-only medicines consisted of 59.2% of self-medication. The practice of self-medication and the use of prescription-only medicines were more prevalent among students in their fifth year and among males. While the prevalence of medicine use was the same among males and females, it differed between students in the fifth and first year. Paracetamol, anti-infectives, and non-steroidal anti-inflammatory drugs (NSAIDs) were more frequently used medicines. Conclusion: The use of medicines, self-medication and the use of prescription-only medicines were more prevalent among fifth-year students compared to those in the first-year. This apparently reflects the effect of medical education and training. More specific studies are required to address the issue in more detail and to facilitate interventions. The estimation of the prevalence of self-medication by using a short acceptable recall period, confined in those who had used medicines, seems to be more reasonable and accurate than by using a longer recall period in the entire study population. The prevalence of prescription-only medicines in self-medication could also be a useful indicator.
