Drug advertisements for non-prescription (over-the-counter) drugs on the main radio stations in the State of Rio Grande do Sul, Brazil, were analyzed as to the information provided about generic names, pharmaceutical company, composition, and dosage. From August 1995 to January 1996, 250 advertisements for 28 products were recorded. More than 80% of these advertisements provided no information on these topics and thus failed to comply with Brazilian legislation. On the contrary, a large number of advertisements (39%) emphasize absence of risks, with claims such as "no contraindications" inducing consumers to use such drugs indiscriminately. The study showed that drugs were advertised like any other merchandise with no concern over fundamental information such as product identification, precautions, and possible side effects.
