If a woman has taken mifepristone (the first pill taken to start a medical abortion) and is second guessing her decision, she can request an abortion pill reversal at our center. Highest success rates are seen when a woman requests this reversal within 24 hours of taking mifepristone, but some success has been seen up to 72 hours after the ingestion of the first abortion pill, so long as the second pill (misoprostol) has not yet been taken.
