Summary: Self-medication with OTC and prescription-only medicines (POMs) are pervasive in China, although the latter is an inappropriate practice. The researchers examined the relationship between socioeconomic status (SES) and self-medication with OTCs versus POMs. In ther study sample, 32.69% and 15.02% of people had self-medicated with OTCs and POMs in the 4 weeks before the survey, respectively. OTC use by income exhibited an inverse U shape. Respondents from middle income groups were more likely to self-medicate with OTCs compared with those from the lowest and highest income groups. There was a clear trend towards more self-medication with OTCs, but not POMs, among those with higher educational attainment.
