Taking Mifepristone & Misoprostol: How it Works & The Side Effects
The abortion pill is also called an Early Medical Abortion (EMA). These pills provide a safe way to end an early pregnancy. You can have an EMA with abortion pills up to 10 weeks into the pregnancy.
What is Mifepristone?
Mifepristone is an oral tablet that when used in regimen with Misoprostol tablets, ends a pregnancy gestation that is 10 weeks or less.
- Mifepristone works by blocking progesterone, a hormone needed to sustain pregnancy, which stops the pregnancy from progressing.
- Misoprostol then softens the cervix and triggers uterine contractions, leading to the expulsion of the pregnancy.
How to Take Mifepristone & Misoprostol
It is essential that you follow the guidelines of your healthcare provider when taking this medication and that you report to them immediately if you show signs of allergic reaction or other side effects.
The typical dosage for ending a pregnancy involves taking one 200 mg tablet of mifepristone on Day 1, followed by 800 mcg of misoprostol (four 200 mcg tablets) 24 to 48 hours later.
The mifepristone tablet is swallowed whole, while the misoprostol tablets are placed inside your cheek (buccally). To do this, put two tablets on one side of your mouth between your upper lip and gum, and two on the other side.
Let them dissolve for 30 minutes, then swallow any remaining pieces with water or another liquid. Alternatively, they can be taken vaginally, inserting all tablets into the vagina.
Bleeding usually begins around 2 hours after taking the second pills. There will also be some pain and cramping. Most people will not bleed after taking the first pill. The abortion usually takes place between 2 - 12 hours after taking the second pills.
What Are the Side Effects of Mifepristone?
Common side effects of mifepristone when used to terminate a pregnancy include:
- Excessive vaginal bleeding
- Incomplete abortion
- Infection
- Allergic reactions
- A feeling of light-headedness
- Feeling feverish
- High temperature
- Diarrhoea
- Nausea or sickness
Call our aftercare line if you do not bleed or suffer from the above symptoms.
How Much Will I Bleed During a Medical Abortion?
Bleeding can differ from person to person and with each abortion experience. During a medical abortion, it's normal to have light, moderate, or heavy bleeding. Not everyone will pass blood clots, but for those who do, the clots should not be larger than the size of a lemon. It’s important to have sanitary towels that are suitable for a heavy flow at home.
How Long Do Mifepristone Side Effects Last?
If you are not already experiencing vaginal bleeding after taking mifepristone, it will likely begin after taking misoprostol. You must use menstrual pads rather than tampons or menstrual cups so you can monitor your blood flow.
You can expect bleeding or spotting for an average of 15 days, and it may continue for up to 30 days. The bleeding may be similar to or heavier than a normal period, and you may pass blood clots and tissue, which is a normal part of the process.

FAQS on Mifepristone & Misoprostol:
Mifepristone, in combination with misoprostol, should not be used for medical termination if more than 70 days have passed since the first day of your last menstrual period, or if you:
- Have an ectopic pregnancy (a pregnancy outside the uterus)
- Have adrenal gland issues (glands located near the kidneys)
- Are on long-term corticosteroid treatment
- Have had an allergic reaction to mifepristone, misoprostol, or similar medications
- Have bleeding disorders or are taking blood-thinning medications
- Have inherited porphyria (a rare disorder affecting the liver and other organs)
Mifepristone is a medication that blocks progesterone, a hormone essential for maintaining pregnancy. When combined with another drug called misoprostol, it is used to terminate a pregnancy up to 10 weeks gestation.
Most pregnancies are passed 2 to 24 hours after taking the misoprostol tablets. Mifepristone alone will not terminate a pregnancy.
Misoprostol is designed to gradually soften the cervix. It can take several hours. This enables the body to expel the foetus from the uterus. It is used not just for abortion but also to induce labour in women who are ready to give birth.
Insert all 4 tablets vaginally one at a time, this may be easiest laying down. Lay down for 30 minutes after inserting to ensure they start dissolving properly.
If you prefer, place them between your gum and cheek. You can take your preferred pain relief 10 minutes before taking the misoprostol.
No, contraceptive pills will not end a pregnancy. Mifepristone contains the hormone that ends a pregnancy, whereas the contraception pill contains hormones that prevent ovulation and thicken the lining of the uterus.
