Non-surgical abortion methods have the potential to improve the quality and safety of women's reproductive health in the developing world. However, until recently, widespread availability and utilization of medical abortion with mifepristone in low resource countries has been restricted by the limited availability of mifepristone and perceived high cost of the drug, while the low and varied rates of efficacy of the misoprostol alone regimens have hindered its widespread adoption. In recent years, a handful of new mifepristone and misoprostol products have come to the market, easing the availability and reducing the cost of both drugs, and therefore making their introduction in new settings more feasible. Nonetheless, mifepristone is much more expensive than misoprostol (approximately $4 - 6 a tablet versus $0.35 a tablet) and often a large part of the cost of the medical abortion cost. In this respect, this study provides an important opportunity to better understand the real difference in efficacy of the two regimens in addition to the costs and benefits of these two non-surgical abortion regimens.
