Internet use is increasing rapidly. According to 2020 data, 90.7% of households have access to the internet at home in Turkey. Due to the rapid use of the internet, the concept of social media has raised. The most important feature that distinguishes social media from other communication tools is that it creates an interaction environment and a continuous flow of information. These platforms are frequent- ly used to access to information on health. Collaborative hypertext dictionaries have been among these platforms. Research show that a large part of the society has made health-rela- ted internet search at least once, mostly to access to the information about disease and medical content. Internet users who have insuffi- cient health literacy may not critically evaluate or misinterpret the information which they access. Such cases may be harmful both for the individual and community health. In this article, we aimed to reveal the importance of internet and so- cial media including collaborative hypertext dictionaries to access to the correct information on health and to propose recommenda- tions for the effective use of social media by health professionals.
