Second-Trimester Medical Abortion with Misoprostol Preceded by Two Sequential Doses of Mifepristone: An Observational Study.

Second-trimester medical abortion using two sequential doses of mifepristone followed by misoprostol reduced the IAI and misoprostol requirement without adding any extra days to the existing regimen. Further randomized studies can assess if the 'two-dose' mifepristone regimen is more efficient than the 'one-dose' regimen.
