How Does Mifeprex Work?
Mifeprex is a pill that blocks progesterone, a naturally produced hormone that prepares the lining of the uterus for a fertilized egg and helps maintain pregnancy. Without progesterone the pregnancy cannont continue and the lining of the uterus softens, breaks down and bleeding begins. Mifeprex is followed by a prostaglandin, misoprostol, which causes the uterus to contract and helps to complete the process. For additional information on Mifeprex you may want to read the Medication Guide.
