The use of misoprostol for abortifacient purposes is a phenomenon observed in Brazil since the late 1980s. The drug started to be used at that time for self-induced abortion, when it began to be commercialized for the treatment of peptic ulcer. Its access was restricted from 1998 onwards, but the drug continues to be commercialized illegally. The objective of this article is to summarize the knowledge produced by research in Brazil about induced abortion and the use of misoprostol. An integrative review of original studies carried out in Brazil and published in journals indexed in SciELO, PubMed and Lilacs databases was performed. The search found 68 titles, and 28 articles were included in the review. Most women who induced pregnancy interruption were young and did it before 15 gestational weeks. The rate of misoprostol use ranged from 89% to 36%. This drug is effective for terminating pregnancy in the first trimester and has a low rate of complications. However, the more socially vulnerable the woman is, the greater are the health risks in the abortion process. The conclusion is that the purchase of misoprostol as an abortifacient is facilitated, despite it being prohibited, and its complications are associated with the context of vulnerability of the pregnant woman.
