Self-medication is a form of self-care which has evolved considerably with the development of digital technology. It particularly challenges public health actors given the risks to which it may be exposed if it is not properly supervised. The aim of this work was to study the knowledge, attitudes and practices of Senegalese women on self-medication through social networks. A transversal descriptive study was conducted from June 10 to 30, 2019. It concerned all Senegalese women registered in at least one of the following women's Facebook groups: Femme chic, Femme leader, Ladies club or Entre yaays.
