Use mifepristone as directed by your doctor. Check the label on the medicine for exact dosing instructions. Mifepristone comes with an extra patient information sheet called a Medication Guide and a Patient Agreement. Read them carefully. Read them again each time you get mifepristone refilled. Mifepristone is supplied by your health care provider and is not available at a pharmacy. Mifepristone requires 3 visits to your health care provider. On day 1 at your health care provider's office, you will read the Medication Guide and discuss the benefits and risks of using mifepristone to end your pregnancy. If you decide mifepristone is right for you, sign the Patient Agreement. After your physical exam, you will take 3 tablets of mifepristone. On day 3 at your health care provider's office, if you are still pregnant, you will take 2 misoprostol tablets. Misoprostol may cause cramps, nausea, diarrhea, and other symptoms. Your health care provider may give you other medicines for these symptoms. Around day 14 at your health care provider's office, you will return for an important follow-up visit. You must return about 14 days after you have taken mifepristone to be sure the pregnancy has ended. If the pregnancy has not ended, there is a chance of birth defects. Your health care provider will discuss with you your choices, including surgical abortion. Grapefruit and grapefruit juice may increase the risk of side effects from mifepristone. Talk to your doctor before including grapefruit or grapefruit juice in your diet while taking mifepristone. You must follow the dosing schedule as directed by your doctor. If you miss an appointment, contact your doctor immediately.
Ask your health care provider any questions you may have about how to use mifepristone. Important safety information: Mifepristone may cause dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use mifepristone with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it. Make sure that your health care provider gives you clear instructions and a telephone number that you can call in case of an emergency or if you have any problems or concerns. If you are using an IUD, it should be removed before treatment with mifepristone begins. Mifepristone should not be used if your pregnancy is outside the womb (ectopic pregnancy). It will not cause an abortion in this case. In fact, it may cause very serious internal or external bleeding. You can become pregnant again immediately after using mifepristone. To avoid pregnancy, start using birth control as soon as your pregnancy ends and before you start having sexual intercourse again. Tell your doctor or dentist that you take mifepristone before you receive any medical or dental care, emergency care, or surgery. Take the Medication Guide with you if you go to an emergency room or another health care provider so they will know that you are taking mifepristone. Lab tests, including human chorionic gonadotropin (hCG) levels and ultrasonographic scan, may be performed while you use mifepristone. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments. Mifepristone should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed. PREGNANCY and BREAST-FEEDING: Mifepristone usually causes fetal death. In the unlikely event you have an ongoing pregnancy after treatment, birth defects may result. It is not known if this medicine is found in breast milk. Because the effects of mifepristone on infants are not known, contact your doctor if you are breast-feeding to determine if you should discard your breast milk for a few days following treatment.
