OTC Medicine Safety, a free, easily accessible, in-classroom educational program available through Young Minds Inspired (, was developed to improve adolescents’ knowledge of safe use of medicines. In a proof-of-concept study, students increased knowledge about safe, appropriate use of over-the-counter (OTC) medicines. In this study, we assessed whether the OTC Medicine Safety program effectively increased students’ knowledge and if students retained this knowledge over time.


We measured student knowledge before implementation (baseline, Quiz 1) immediately after implementation (Quiz 2), and 10 weeks after baseline (Quiz 3) in 3 test schools. We measured knowledge at similar intervals in 3 control schools (no program implementation).


Baseline knowledge was low (average 39.3% of 36 questions answered correctly). Among intervention schools, scores significantly improved immediately (average correct 62.9%) after implementation and were retained at 10 weeks (59.8%) (p < .001). Change in score from baseline among intervention schools immediately after the lesson implementation was significantly higher than corresponding changes from baseline among control schools (intervention: +23.0 vs control: -3.2) and at 10 weeks (intervention: +19.9 vs control: -2.9), p < .001.


The OTC Medicine Safety Program effectively improved students’ knowledge of safe medicine-taking practices and students retained this knowledge at 10 weeks.
