Delgado’s strategy is to give women who have taken the mifepristone but then have second thoughts an injection of extra progesterone to compete with the mifepristone for the woman’s progesterone receptors and if successful, allow the pregnancy to continue. In 2012 Delgado and a colleague published a paper about the technique in the Annals of Pharmacotherapy, a peer-reviewed print and online journal.
The tone of the paper was cautious; it reported that four out of six women who had taken progesterone had reversed the effects of the mifepristone (a seventh woman failed to follow up with Delgado). According to the abstract, a progesterone “may reverse the effects of mifepristone.”
