About Mifeprex

Mifeprex is used to end an early pregnancy. It blocks a hormone needed for your pregnancy to continue. It is not approved for ending later pregnancies. Early pregnancy means it has been 49 days (7 weeks) or less since your last menstrual period began. When you use Mifeprex (Day 1), you also need to take another medicine, misoprostol, 2 days after you take Mifeprex (Day 3), to end your pregnancy. About 5-8 out of 100 women taking Mifeprex will need a surgical procedure to end the pregnancy or to stop too much bleeding.

Side Effects of Mifeprex

  • Cramping and Bleeding are expected with this treatment. Usually, these symptoms mean that the treatment is working. But sometimes, you can get cramping and bleeding and still be pregnant. This is why you must return to your healthcare professional on Day 3 and on about Day 14. If you are not already bleeding after taking Mifeprex, you probably will begin to bleed once you take misoprostol, the medicine you take on Day 3. Bleeding or spotting can be expected for an average of 9–16 days and may last for up to 30 days. Your bleeding may be similar to, or greater than, a normal heavy period. You may see blood clots and tissue. This is an expected part of ending the pregnancy.

Although cramping and bleeding are an expected part of ending a pregnancy, rarely, serious and potentially life-threatening bleeding, infections, or other problems can occur following a miscarriage, surgical abortion, medical abortion, or childbirth. Prompt medical attention is needed in these cases.

Be sure to contact your healthcare professional right away if you have any of the following:

  • Heavy Bleeding. Contact your healthcare professional right away if you bleed enough to soak through two thick full-size sanitary pads per hour for two consecutive hours or if you are concerned about heavy bleeding. In about 1 out of 100 women, bleeding can be so heavy that it requires a surgical procedure (surgical abortion/D&C) to stop it.
  • Abdominal Pain or Feeling Sick. If you have abdominal pain or discomfort, or you are feeling sick with symptoms including weakness, nausea, vomiting or diarrhea, with or without fever, more than 24 hours after taking the misoprostol, you should contact your healthcare professional right away. These symptoms may be a sign of a serious infection or another problem (including an ectopic pregnancy, a pregnancy outside the womb).
  • Fever. In the days after treatment, if you have severe abdominal pain or a fever of 100.4°F or higher that lasts for more than 4 hours, you should contact your healthcare professional right away. Fever may be a symptom of a serious infection or another problem (including an ectopic pregnancy, a pregnancy outside the womb).

Who Should Not Take Mifeprex

Do not take Mifeprex if:

  • It has been more than 49 days (7 weeks) since your last menstrual period began.
  • You have an IUD. It must be taken out before you take Mifeprex.
  • Your doctor has told you that you have a pregnancy outside the uterus (ectopic pregnancy).
  • You have problems with your adrenal glands (chronic adrenal failure).
  • You take a medicine to thin your blood.
  • You have a bleeding problem.
  • You take certain steroid medicines.
  • You cannot return for the next 2 doctor’s office visits.
  • You cannot easily get emergency medical help in the 2 weeks after you take Mifeprex, if you need it.
  • You are allergic to mifepristone, misoprostol, or medicines that contain misoprostol, such as Cytotec or Arthrotec.
