Uses
Mifepristone (also known as RU 486) is used to end a pregnancy during the early part of a pregnancy. It is used up to week 10 of pregnancy (up to 70 days after the first day of your last menstrual period). Mifepristone blocks a natural substance (progesterone) that is needed for your pregnancy to continue. It is usually used together with another medicine called misoprostol.Mifepristone must not be used if you have a rare abnormal pregnancy that is outside the womb (ectopic pregnancy). It will not end the pregnancy in this case. It may cause an ectopic pregnancy to rupture, resulting in very serious bleeding.
How to use Mifepristone 200 Mg Tablet Abortifacients
Read the Medication Guide provided by your doctor before you start using mifepristone. Keep the guide to reread if needed. Read and sign the Patient Agreement form provided by your doctor. If you have any questions, consult your doctor or pharmacist.
You must visit the doctor's office at least 2 times to complete your treatment and important examinations. This treatment is only given under direct medical supervision. Learn about who to call and what to do in case of an emergency.
Your doctor may order an ultrasound to make sure your pregnancy is less than 10 weeks and is not outside the womb (ectopic).
Take mifepristone by mouth as directed by your doctor, usually as a single dose. After taking mifepristone, your doctor should direct you to wait 24 to 48 hours before taking another medication (misoprostol) by mouth as a single dose. The medications may not work well if you take misoprostol sooner than 24 hours after taking mifepristone or later than 48 hours after taking mifepristone. Follow your doctor's instructions carefully. Heavy vaginal bleeding does not mean that the pregnancy has ended.
Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.
It is important that you return for a follow-up visit within 7 to 14 days after taking mifepristone, even if you are not having any problems.
If the pregnancy has not ended, or there are serious medical problems, surgery may be needed. If the treatment fails and the pregnancy continues until birth, there is a risk of birth defects.
Side Effects
See also Warning section.
Nausea, vomiting, diarrhea, weakness, or dizziness may occur. If these effects last longer than the first 24 hours after taking the second drug (misoprostol), get medical help right away because they can be signs of a serious medical problem.
Bleeding and cramping are expected during this treatment. Usually, the symptoms mean the drugs are working. However, sometimes you can have cramps and bleeding and still be pregnant. You must return for all of your follow-up visits with your doctor. Nausea and cramping may get worse in the 24 hours after you take the second drug (misoprostol). Your doctor may direct you to take other medication to help with these symptoms. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Bleeding and spotting may last up to 30 days and may be much heavier than a normal period. In very few cases, this bleeding will need to be stopped by surgery. Get medical help right away if you bleed enough to soak through 2 thick, full-size sanitary pads each hour for 2 hours in a row, or if you are concerned about heavy bleeding.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Get medical help right away if you have any very serious side effects, including: fever of 100.4 degrees F (38 degrees C) or higher, fainting, fast heartbeat, stomach/abdominal pain or tenderness.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Warnings
Rarely, serious medical problems can occur when a pregnancy ends, including sometimes fatal infections and bleeding. Read the Medication Guide, read and sign the Patient Agreement, and consult your doctor if you have any questions. To receive mifepristone in the United States, you must understand, agree to, and carefully follow the requirements of the REMS Program for this medication. If you live in Canada or any other country, consult your doctor and pharmacist for your country's regulations.
Your doctor must give you clear instructions about who to call and what to do in case of an emergency (such as severe bleeding, infection). If you go to the emergency room or visit another health care professional, show them the Medication Guide so they know you are trying to end your pregnancy.
Get medical help right away if you experience symptoms such as severe abdominal pain, fainting, fast heartbeat, fever lasting more than 4 hours. You may have a very serious infection even if you do not have a fever. Get medical help right away if you have abdominal pain or feel sick (for example, if you have nausea, vomiting, diarrhea, weakness) more than 24 hours after taking the second drug (misoprostol), even if you do not have a fever. Also get medical help right away if you have continued heavy bleeding, which may be a sign the pregnancy has not ended or other serious medical problem. You may need surgery or other medical care.
