If you think you may be pregnant and you’re considering ending pregnancy through at-home abortion using medication, you have the option to reverse an abortion using prescription medication. This article contains information about abortion reversal treatment—what it involves and important factors to consider helping sort out whether abortion reversal treatment may be an option for you.
What is Abortion Reversal?
At-home abortion pills contain two active ingredients to end pregnancy—mifepristone and misoprostol. Usually mifepristone is taken first, followed by misoprostol roughly 24 to 48 hours apart. Once a woman takes these two medications, their active ingredients can work within a matter of hours or days to end pregnancy by changing internal hormonal balance. Reversing this treatment is possible, however, if you or someone you know is having second thoughts about following through on abortion. Progesterone may be most effective in stopping an abortion if it is taken after the first dose of mifepristone1,2,3.
Treatment to reverse the effect of misoprostol and mifepristone can effectively stop pregnancy-ending hormonal changes through injectable or oral progesterone. The medication progesterone consists of a hormone naturally secreted by the corpus luteum (a temporary part of the ovary) to support pregnancy4. To stop an abortion, progesterone is used to block the effect of mifepristone1, 2. Pregnancy continuation using prescription progesterone can work successfully if a woman changes her mind and chooses pregnancy instead of abortion2.
Side Effects in Perspective
At-home abortion medication can cause side effects ranging from cramping to nausea, headaches, or cramping to name a few5-6. Progesterone is a common ingredient in oral contraceptives, so side effects of abortion reversal treatment are similar to those of progesterone-only contraceptives: headaches, fatigue, vomiting, and constipation are some potential side effects5. Mifepristone taken alone can cause bleeding which could be severe, so it is essential to contact an experienced medical professional to seek help in assessing your own medical history and any health concerns or questions about the potential risks and benefits of treatment that apply uniquely to you. Staying in contact with clinical team members in the days following treatment for abortion reversal is an important step in safeguarding your health to ensure you do not experience bleeding or other health problems and to intervene quickly if any concerns or questions arise.
