Early pregnancy termination with pills – Steps, timing, and follow-up guidance for a safe medical abortion.
What Are Abortion Pills?
Abortion pills usually involve two medications: mifepristone and misoprostol. Mifepristone blocks progesterone, a hormone necessary to maintain pregnancy, while misoprostol triggers uterine contractions to expel the pregnancy.
This combination is considered safe and effective for early pregnancy termination.
Timing of Abortion Pills
Abortion pill timing depends on how the medications are taken:
- Mifepristone – Typically taken first. It starts to work within a few hours by stopping the pregnancy from progressing.
- Misoprostol – Usually taken 24–48 hours after mifepristone. It induces cramping and bleeding, which are the main signs that the abortion is underway.
How Long Abortion Pills Take to Work
- Onset of bleeding: Most people experience bleeding within 1–4 hours of taking misoprostol, though for some it may take up to 24 hours.
- Passing tissue: The pregnancy is usually expelled within 4–6 hours, but the entire process can take up to 24 hours.
- Cramping: Cramping often starts shortly after misoprostol is taken and may continue for several hours.

- Bleeding and clots – Heavier than a normal period
- Cramping and abdominal pain – Can vary in intensity
- Passing tissue – Grayish or pink tissue may be seen

Factors Affecting Timing

Follow-Up After Abortion Pills
