This study examined the efficacy and acceptability of a medical abortion regimen using mifepristone and sublingual misoprostol, and compared the effectiveness at 64-70 days’ LMP to that at 57-63 days’ LMP. Neither the rates of success not the rates of ongoing pregnancy differed significantly between the two gestational age groups, suggesting that this regimen can be offered up to 70 days’ LMP.
