If you take only mifepristone and do not take misoprostol, the abortion process will often be incomplete, and there is a significant possibility that the pregnancy will continue.
Mifepristone works by blocking progesterone, the hormone necessary to maintain a pregnancy, which causes the uterine lining to break down. However, it generally does not cause the uterus to empty on its own. Misoprostol is the second medication required to induce the uterine contractions necessary to expel the pregnancy tissue.
What to Expect If Only Mifepristone Is Taken
-
Pregnancy Continuation Risk: Without taking misoprostol 24 to 48 hours later, a substantial percentage of pregnancies will continue to grow.
-
Birth Defect Risks: If a pregnancy continues after taking mifepristone alone, there is a known risk of severe fetal anomalies and birth defects. Because of this, clinical guidelines emphasize that mifepristone must always be followed by misoprostol to ensure the procedure is completed.
-
Delayed Bleeding or Mild Spotting: You may experience minimal spotting or light cramping after taking mifepristone alone, but this does not mean the abortion has occurred.

What Steps to Take If You Missed Misoprostol
If you accidentally missed taking misoprostol or ran into issues during your medication regimen, it is vital to contact a healthcare provider immediately for medical guidance:
-
Complete the Regimen or Seek Follow-Up: Depending on the timing, a clinician may advise you on taking the remaining medication safely or provide further evaluation. For a detailed breakdown of how medication protocols and recovery steps work, review our overview on how a virtual abortion works.
-
Monitor Your Symptoms: If you experience severe pain, heavy bleeding, or signs of an incomplete process, contact a medical professional right away. You can also read our clinical resource on managing cramps and heavy bleeding for guidance on recovery milestones.
