Information about benzodiazepines: what does the internet offer us?

This study analysed the quality of information published on the internet regarding 4 benzodiazepines that are widely used in Brazil: alprazolam, bromazepam, clonazepam and diazepam. This choice is justified by the fact that these drugs are widely used and can generate chemical dependency, and the internet is an important source of information about them. We analysed 20 sites for each drug. More than half (56.3%) of the sites were classified as deficient or very deficient. The most frequent problems with the sites were the absence of a description of the person responsible for the site (60%), incomplete information (62.5%), the absence of a contact for additional information (45%) and the absence of the last date the site was updated (82%). These results reinforce concerns regarding the quality of the health information published on the internet, which has already been noted in the literature, and the need to adopt minimum quality criteria for this information.
