This article puts into perspective the controversy between the association of the use of misoprostol for abortion and teratogenicity studies of the type found in a case report. The use of herbal medicinal drugs and the medical-obstetric and national and international norms governing the registration and circulation of pharmaceutical products were examined. Official documents of ANVISA, the Ministry of Health and the World Health Organization on the use of misoprostol, as well as 68 articles such as case reports published in national journals, linking abortion, misoprostol and teratogenicity were reviewed, systematically filed and analyzed using the monographic method. The legal prohibition of abortion prevents the proper prescription and use of a drug such as misoprostol that is both safe and effective. Thus, the danger for the health of women is linked not to the intrinsic characteristics of the drug, but to the moral arguments that constitute negligence and disregard for the fundamental rights of women.
