A consecutive series of 360 women with pregnancies of up to 63 days of
amenorrhoea requesting medical abortion were managed using a low-cost
regimen of mifepristone (200 mg) followed by vaginal administration o
f misoprostol (800 mu g). Results in terms of complete abortion rate,
continuing pregnancy rate and proportion of women aborting within six
hours were similar to those described with the standard medical aborti
on regimen of mifepristone (600 mg) and gemeprost (1 mg). The reported
regimen thus combines clinical effectiveness with costs which are low
er than those associated with the standard treatment or with suction t
ermination.
