Are federal rules that limit access to “medical abortion” justified? According to the American Civil Liberties Union (ACLU), the answer is no. Earlier this month, the ACLU filed a lawsuit against the U.S. Food and Drug Administration (FDA), challenging regulations that restrict access to the drug mifepristone. Mifepristone is marketed in the United States under the brand name Mifeprex. It can be administered in combination with the drug misoprostol to induce miscarriage.
