title: Over-the-counter and Prescription Medications for Acne: A Cross-Sectional Survey in a Sample of University Students in Saudi Arabia.
abstract: BACKGROUND
  Acne is a very common dermatological condition found among the adolescent population in Saudi Arabia. Many patients with acne try various forms of self-medication, over the counter medicines (OTC), and prescription medicines for the same.
  
  
  METHODS
  This was a cross-sectional study among university students in the Kingdom of Saudi Arabia (KSA). A validated questionnaire was distributed to a convenience sample of university students to evaluate their knowledge and attitudes towards OTC (mainly) as well as prescription medicine for acne. Chi-square and multiple logistic regression tests were used for comparisons between groups.
  
  
  RESULTS
  Four hundred and twenty valid, completed questionnaires were obtained. A total of 220 (52.4%) used some type of OTC medications at least once, where as 108 (25.7%) used prescription medicines and 92 (21.9%) used both. The most common OTC medications used were cleansers by 250 participants (41.9%). Among prescription medicines, the most common were topical and oral antibiotics (11.4%). Bivariate and multivariate analysis showed that females are statistically more likely to use OTC medicines compared to males (Odds ratio: 1.7).
  
  
  CONCLUSIONS
  The use of self-medications and OTC medications is common among university students in KSA. The most common OTC medicine used for acne was cleanser.
