More scientific information:
Research has shown that for women with pregnancies of 8 weeks or less, Misoprostol works with the same efficacy whether it is taken at 12 hours, 24 hours, 48 hours, or as much as 85 hours after Mifepristone 7 . Though we instruct women to take Misoprostol 24 hours after Mifepristone and strongly encourage women to follow all the instructions for proper use, if a woman takes it slightly earlier or later, this does not effect the outcome of the medical abortion.
