Medication abortion with misoprostol-only is one of two safe, highly effective, WHO-recommended regimens for medication abortion. Our SAFE Study and other findings support a renewed look at misoprostol-only regimens for medication abortion, no longer as a second-tier method, but one that offers similar effectiveness, and often greater accessibility, than the mifepristone + misoprostol regimen.


Ibis research shows that misoprostol-only is highly effective, and more effective than previously thought.

According to data from our SAFE Study, 93.8% of those who used the mifepristone + misoprostol regimen had a complete abortion without surgical intervention, while 98.8% of those who used the misoprostol-only regimen had a complete abortion without surgical intervention. Findings from the first study on self-managed abortion with misoprostol only in the United States reflect this data, with 88% overall effectiveness and 97.8% effectiveness among known outcomes.

Additionally, misoprostol-only is less costly, carries fewer restrictions for use, and can be offered by a wider cadre of providers.
