Rational drug use workshops were conducted in various centres in India. The effects of these workshops on some of the indicators for rational drug use are discussed. An evaluation based on responses to questionnaires does not permit the measurement of the effects on practice changes, and only perceived changes by the respondents are indicated. Within the short period of evaluation, drug use skills and awareness about various aspects of rational drug use are perceived to have improved. There is a need to re-emphasize through personal interaction and workshops the concept of rational drug use.
