False information and faulty science regarding the safety of the drug mifepristone, which is used in the vast majority of medication abortions in the United States, is at the center of a narrative that may further reduce abortion access. Mifepristone, and medication abortion more broadly, is safe, effective and widely used in the United States and globally. Despite its demonstrated safety, relentless policy and legal attacks aim to restrict or even ban access to this method of abortion.
This analysis will explore and counter several pernicious aspects of such attacks. These include the misrepresentation of normal signs a medication abortion is working as intended—for example, cramping or bleeding—as serious medical complications; and the conflation of routine or precautionary care-seeking by medication abortion patients with emergency treatment for serious adverse events.
