What is Mifepristone?

Mifepristone is a prescription medication that safely ends an early pregnancy. It is the first of two pills used in a medication abortion, followed by Misoprostol.

Mifepristone works by blocking the hormone progesterone, which is essential for maintaining pregnancy. Without progesterone, the pregnancy stops growing, and the lining of the uterus begins to break down, preparing the body for the second step of the process.

Mifepristone has been used safely worldwide for over two decades and is recommended by leading health authorities, including the World Health Organization (WHO) and the Royal College of Obstetricians and Gynaecologists (RCOG).

How Does Mifepristone Work for Abortion?

A medication abortion consists of two essential steps. First, you take Mifepristone, which blocks the body's ability to maintain the pregnancy by interfering with progesterone. After taking Mifepristone, most people do not experience major changes right away. You might have light spotting or mild cramping, but it's normal to feel largely the same until the second step.

The second step involves taking Misoprostol 24 to 48 hours later. Misoprostol causes the uterus to contract and expel the pregnancy tissue, leading to cramping and heavier bleeding, similar to a miscarriage.

As Dr. Albert Aka, Consultant Gynaecologist at Top at Home, explains: "Mifepristone is a critical part of medication abortion. It prepares the body for a smooth and effective process, ensuring that Misoprostol can work safely and efficiently."

How to Take Mifepristone: Step-by-Step

Taking Mifepristone is simple. You'll swallow one tablet (200mg) with a glass of water. It's best to take it at a time and place where you feel calm and comfortable. You can eat and drink as normal before and after taking the pill.

Most people feel fine immediately after taking Mifepristone. Some may experience light cramping, spotting, or mild nausea, but many continue with their daily activities without disruption.

A helpful tip from our clinical team: if you vomit within 30 minutes of taking the pill, you should contact us. In rare cases, you might need another dose to ensure it works properly.

After taking Mifepristone, you will move on to the second step, taking Misoprostol 24 to 48 hours later. During your consultation, we’ll give you detailed, easy-to-follow instructions for the next step.

If you need reassurance at any point, our team is available via WhatsApp or phone for support.

What to Expect After Taking Mifepristone

Since Mifepristone is the first stage, many people feel few or no physical symptoms. Mild cramping or light bleeding can happen, but it’s also completely normal not to notice any changes until after taking Misoprostol.

Some people report mild side effects such as slight nausea, headache, or feeling a little tired, but these symptoms typically pass quickly. It's safe to carry on with your daily activities unless you feel unwell, in which case rest and hydration are key.

Dr. Aka's advice: "After taking Mifepristone, most people feel completely fine and can go about their day. The real changes happen after taking Misoprostol."

You should seek medical advice if you experience severe abdominal pain that doesn't respond to painkillers, heavy bleeding before taking Misoprostol, or persistent nausea, vomiting, or dizziness.

How Effective is Mifepristone?

When taken with Misoprostol, Mifepristone is highly effective working successfully for about 98% of people.

If the abortion is not complete, a second dose of Misoprostol or additional treatment might be needed, though this is uncommon. Most people’s bodies respond as expected after following the two-step process.

You can confirm that the abortion was successful by taking a pregnancy test 3 to 4 weeks after treatment. Testing earlier could result in a false positive because pregnancy hormones may still be present.

Periods usually return within 4 to 6 weeks, another sign your body is returning to its usual cycle.

Is Mifepristone Safe?

Mifepristone is considered extremely safe when used under proper medical guidance. It has a lower risk of complications than many routine medical procedures, including wisdom tooth removal or even full-term childbirth.

The complication rate for Mifepristone is very low (less than 0.4%), and it is endorsed for use by trusted organisations like the WHO and the NHS.
