This product is used to cause an abortion during the early part of a pregnancy. It is used up to 63 days after the first day of your last menstrual period. This product contains 2 medications: mifepristone and misoprostol. Mifepristone works by blocking a natural hormone (progesterone) that is needed for the pregnancy to continue. Misoprostol works by making the womb (uterus) contract and the opening of the cervix relax, which causes the contents in the womb to pass out of the body.
Mifepristone and misoprostol must not be used if you have a rare abnormal pregnancy that is outside the womb (ectopic pregnancy). In this case, abortion will not occur and the ectopic pregnancy may suddenly break, resulting in very serious bleeding.
How To Use
See also Warning section.
Before treatment, your health care professional must make sure your pregnancy is not outside the womb (ectopic), and check how long you have been pregnant.
Read the Patient Information Leaflet provided by your health care professional before you start using this product. If you have any questions, ask your health care professional. Read and sign the consent form and Patient Information Card provided by your health care professional and keep the Patient Information Card with you while using this product and until your health care professional tells you that your abortion is complete.
Take mifepristone by mouth as directed by your health care professional, usually as a single dose. Swallow the mifepristone with a glass of water. After taking mifepristone, wait 24 to 48 hours, then take the misoprostol (as a single dose). To take the misoprostol, place the tablets between your cheeks and gums and allow to dissolve for 30 minutes. If there are still some tablet pieces left in your mouth after 30 minutes, swallow them with a glass of water. Plan to rest for 3 hours after taking the misoprostol tablets. The medications may not work as well if you take misoprostol sooner than 24 hours after taking mifepristone or later than 48 hours after taking mifepristone. Carefully follow your health care professional's directions. Heavy vaginal bleeding does not mean that an abortion is complete. Be sure you know who to call and what to do in case of emergency.
Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your health care professional says you may do so safely. Grapefruit can increase the chance of side effects with mifepristone.

Breast tenderness, headache, nausea, vomiting, diarrhea, tiredness, or dizziness may occur. If nausea, vomiting, diarrhea, or weakness last longer than 24 hours after taking the second drug (misoprostol), get medical help right away.
Bleeding and cramping are expected during this treatment. Vaginal bleeding usually starts a few hours after taking the misoprostol. These symptoms usually mean the drugs are working. However, sometimes you can have cramps and bleeding and still be pregnant. You must keep all of your follow-up visits so your health care professional can check if abortion is complete.
Nausea and cramping may get worse in the first 24 hours after you take the second drug (misoprostol). Your health care professional may direct you to take other medication(s) to help with these symptoms. Bleeding and spotting usually last about 11 days and may be much heavier than a normal period. Rarely, this bleeding may 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 worried about heavy bleeding.
Remember that this product has been prescribed because your health care professional has judged that the benefit to you is greater than the risk of side effects. Many people using this product do not have serious side effects.
