In order to assess the effects of prescription-only (Rx) to over-the-counter (OTC) drug switches and related policies, it is imperative to distinguish self-medication from OTC drug use. The objective of this study was to estimate the OTC drug use in the adult population in Germany, to identify its predictors and to highlight methodological differences when compared to the study of a self-medication prevalence. Seven-day prevalence of OTC drug use was calculated on the basis of information provided by 7091 participants of the German Health Interview and Examination Survey for Adults (DEGS1) conducted between 2008 to 2011.

Methods: Session minutes of the German Expert Advisory Committee for Prescription-Only Issues, changes to the German Ordinance on Prescription-Only Medicines and the Summary of Product Characteristics of the switched substances were analysed.
