MARTIN FOMBELLIDA, Ana Belén et al. Information on drugs and self-medication in social networks. Rev. cuba. inf. cienc. salud [online]. 2014, vol.25, n.2, pp. 145-156. ISSN 2307-2113.

Social networks are one of the main sources of information on the Internet. Objective: evaluate the health information provided by social networks concerning drugs and self-medication. Methods: an observational study was conducted in Facebook and Twitter for three months based on the search terms health, disease and drugs, with the purpose of exploring and analyzing comments on health information. 334 comments were analyzed, randomly selected from the total 1 002 collected. Results: Information on drugs was 20,8 % in Facebook and 24,15 % in Twitter. Information on self-medication was 6,9 % in Facebook and 8,5 % in Twitter. The drugs most commonly commented on were those for the nervous system (Group N) with 76 (22,7 %) comments in Facebook and 78 (23,3 %) in Twitter. This was the prevailing group in both networks. The same therapeutic subgroups stand out in the two networks: N02 (analgesics), higher in Facebook, N06 (psychoanaleptics) and N05 (psycholeptics). As to the drugs used for self-medication, there is a predominance of Group N (nervous system) in both networks, but the prevalence is higher in Facebook. The groups following, all of which stand out in Twitter, are Group R (respiratory system), A (digestive system) and M (musculoskeletal system). Groups M and R rank second in Twitter with the same number of hits. Conclusions: Users of Facebook and Twitter share more information about drugs than about self-medication. Social networks are mostly used to exchange experiences, make inquiries and obtain information about health problems.
