How The Abortion Pill Works (Mifepristone + Misoprostol)

Understanding the medical process of abortion with the use of Mifepristone and Misoprostol can empower individuals with knowledge and clarity.

An Overview of Mifepristone and Misoprostol

The abortion pill consists of two medications: Mifepristone and Misoprostol. These medications are used in combination to safely terminate an early pregnancy. The method is widely regarded for its effectiveness and is commonly chosen by those seeking a non-surgical option for abortion.

Mifepristone is taken first to block the hormone progesterone, which is necessary for pregnancy to continue. Misoprostol is taken 24 to 48 hours later to induce contractions and expel the pregnancy tissue from the uterus. This combination is effective up to 10 weeks of pregnancy.

The Science Behind Mifepristone

Mifepristone, also known as RU-486, works by inhibiting the action of progesterone, a hormone essential for the maintenance of pregnancy. Progesterone supports the endometrial lining of the uterus, which is crucial for a developing embryo. By blocking this hormone, Mifepristone causes the lining to break down and detach.

This process effectively halts the progression of the pregnancy, making the uterus more receptive to the action of Misoprostol. The drug is typically administered orally and begins to work within hours.

How Misoprostol Complements Mifepristone

Misoprostol, the second medication, is taken 24 to 48 hours after Mifepristone. It is a prostaglandin analogue that induces uterine contractions, which help to expel the pregnancy tissue. Misoprostol can be administered orally, vaginally, buccally (in the cheek), or sublingually (under the tongue).

The contractions caused by Misoprostol are similar to those experienced during a miscarriage. This process can take a few hours to complete and is often accompanied by bleeding and cramping, which are signs that the medication is working as intended.

What to Expect During the Process

After taking Mifepristone, most individuals do not experience immediate symptoms, although some may have light bleeding or spotting. The more noticeable effects begin after taking Misoprostol. Within a few hours, cramping and bleeding will start as the uterus expels the pregnancy tissue.

The intensity of the cramps and the amount of bleeding can vary from person to person. It's important to have access to pain relief medications and to rest during this period. The process typically completes within 4 to 6 hours, but some bleeding and cramping can continue for a few days.

Safety and Efficacy of the Abortion Pill

The abortion pill is considered a safe and effective method for terminating an early pregnancy. Clinical studies have shown a success rate of about 95-98% when used within the first 10 weeks of pregnancy. The risk of severe complications is low, but it's important to follow up with a healthcare provider to ensure the process is complete.

Common side effects include nausea, vomiting, diarrhea, and fever, which are usually temporary. Serious complications are rare but can include heavy bleeding, infection, or incomplete abortion. It's crucial to have access to medical care throughout the process and to follow all instructions provided by healthcare professionals.
