Patients first take a pill called mifepristone, which blocks the body’s progesterone, a hormone needed for pregnancy. Within the next 48 hours, patients take a second medication, called misoprostol. The abortion “reversal” pill is taken after women have taken the drug mifepristone but before they have taken misoprostol. The reversal is a high dose of the hormone progesterone in an attempt to counteract the effects of the mifepristone and preserve the pregnancy.
So they would directly go against the patient's wishes? Of course that's unethical.
