Mifeprex Patient Information Including Side Effects

Brand Names: Mifeprex

Generic Name: mifepristone (Mifeprex) (Pronunciation: MIF e PRIS tone)

What is mifepristone (Mifeprex) (Mifeprex)?

Mifeprex blocks the actions of a hormone needed to maintain a pregnancy.

Mifeprex is used to end an early pregnancy (no further along than 7 weeks, or 49 days after the first day of your last menstrual period). Mifeprex is sometimes used together with another medicine called misoprostol (Cytotec).

This medication guide provides information about the Mifeprex brand of mifepristone. Korlym is another brand of mifepristone that is not covered in this medication guide.

Mifeprex may also be used for purposes not listed in this medication guide.

What are the possible side effects of Mifeprex (Mifeprex)?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Bleeding and spotting are normal side effects of Mifeprex. Bleeding may be slightly heavier than a normal period. Call your doctor right away if you bleed enough to soak through 2 full-size sanitary pads per hour for 2 hours in a row.

Call your doctor at once if you have any other serious side effect, such as:

  • general ill feeling and fast heart rate;
  • a fever higher than 100.4 degrees F (38 degrees C);

What is the most important information I should know about Mifeprex (Mifeprex)?

This medication guide provides information about the Mifeprex brand of mifepristone. Korlym is another brand of mifepristone that is not covered in this medication guide.

Mifeprex is used to end an early pregnancy that is not further along than 49 days (7 weeks) after the first day of your last menstrual period. MIFEPREX MUST NOT BE USED IN AN ATTEMPT TO END PREGNANCY BEYOND 7 WEEKS.

Do not use Mifeprex if you do not intend to end your pregnancy. Mifeprex can cause birth defects in an unborn baby if the treatment procedure does not fully terminate the pregnancy. If you are still pregnant after 2 weeks, you may need surgery to end the pregnancy completely.

You should not take Mifeprex if you are allergic to prostaglandins or medicines that contain misoprostol (Cytotec or Arthrotec). Do not take Mifeprex if you have a bleeding or blood clotting disorder, problems with your adrenal glands, an ectopic pregnancy, porphyria, if you take a blood thinner or certain steroid medications, or if you have an intrauterine device (IUD) in place.

Before receiving this medication, you must read a Mifeprex Medication Guide. Then you must sign a Patient Agreement form stating that you understand the risks and benefits of using this medication. Tell your doctor if you have heart disease, high blood pressure, liver or kidney disease, a breathing disorder, diabetes, anemia, or if you smoke.

Treatment with Mifeprex requires 3 visits to your doctor. Do not use this medication if you cannot attend all required follow-up visits.

Mifeprex causes cramping and bleeding, which are signs that medication is working properly. But sometimes you can have cramping and bleeding and still be pregnant. Only your doctor can confirm whether your pregnancy has been completely terminated. Do not miss any follow-up visits.

Call your doctor or seek emergency medical help if you still have any of the following symptoms more than 24 hours after taking Mifeprex: ongoing fever, severe stomach pain, heavy vaginal bleeding, nausea, vomiting, diarrhea, or if you feel like you might pass out.

It is possible to get pregnant again right after terminating a pregnancy with Mifeprex. You may begin using birth control after your doctor has confirmed that treatment with Mifeprex has effectively ended your pregnancy.
