Abortion - Medication

What is Medication Abortion?

Abortion is a way to end pregnancy without surgery. It is done with medications up to 56 days after the last period begins.
Medication abortion using mifepristone involves three steps. First, the doctor will give you mifepristone pills, which block progesterone, a hormone needed to maintain pregnancy. Next, as directed by your clinician, you will take another medication called misoprostol Misoprostol causes the uterus to contract and empty which completes the abortion. Finally, women must return to the clinic a few days after taking the misoprostol for a follow-up.

Effectiveness

Medication abortion with mifepristone is 96-97 percent effective.

Deciding if Medication Abortion is Right for You

Before you decide to have a medication abortion, you will meet with a counselor to discuss the three options regarding a pregnancy - parenthood, adoption, or abortion - and to address any questions or concerns you may have. You will also discuss the risks associated with both medication and surgical abortion. Since mifepristone and misoprostol can cause serious birth defects if the medication abortion does not work, a surgical abortion must be done. Therefore you must agree to have a surgical abortion if the medication abortion does not work. However, you can change your mind at any time before beginning the procedure. Remember that it is entirely your choice to have an abortion.

Before the Medication Abortion

Before you get the mifepristone, you will have:
  • some blood taken from your finger or arm to see if you are anemic (have a "low blood count"), and to see if you are Rh negative. If you are Rh negative, you will get a shot of immune globulin;
  • a vaginal ultrasound (a small wand is placed in the vagina to "see through the tissues" to tell how long you have been pregnant). Vaginal ultrasound works with sound waves so there is no radiation. You may need additional ultrasound examinations at Planned Parenthood or elsewhere
  • a pelvic examination. You may also have testing for sexually transmitted infections, if needed. Vaginal infections will be treated if present.

Beginning the Medication Abortion

You will take the mifepristone pill orally.
You will be given the misoprostol to take home with detailed instructions from the clinic staff about when to use it.
How Long Does It Take?

The process of medication abortion begins immediately after taking mifepristone.  Some women may begin spotting before taking the misoprostol.  For most, the bleeding and cramping associated with medication abortion begin after taking the misoprostol.

More than 50 percent of women who use mifepristone abort within four to five hours after taking misoprostol.  Heavy bleeding may continue for about 13 days.  Spotting can last for a few weeks.  About 92 percent of mifepristone abortions are completed within a week.

What Does It Feels Like?

For most women, medication abortion feels like an early miscarriage. You might:

  • feel strong cramps
  • feel nauseous or vomit
  • have diarrhea
  • feel temporary abdominal pain
  • see large blood clots or tissue at the time of the abortion
  • have some bleeding or spotting for 9-16 days

Acetaminophen or non-steroidal, anti-inflammatory pain relievers such as ibuprofen can reduce most of these symptoms. If needed, a stronger medication may be ordered.

What are the risks of medication abortion?

Medication abortion is safe.  But there are risks with any medical procedure.  Risks associated with medication abortion include
  • incomplete abortion – your clinician will help you decide whether to
    • Wait two-to-six weeks and check again
    • Take more misoprostol
    • Have a vacuum aspiration
  • Allergic reaction
  • Infection
  • Very heavy bleeding
  • Undetected ectopic pregnancy
  • In extremely rare cases death is possible from very serious complications

Contact your clinician right away if at any time you

  • Have a fever of 100.4 degrees or higher that lasts for more than four hours
  • Have heavy vaginal bleeding and are soaking through more than two maxi pads an hour, for two hours or more in a row
  • Have clots for two hours or more that are larger than a lemon
  • Bleed heavily for more than 12 hours in a row
  • Throw up for more than four to six hours and are not able to keep anything down
  • Have abdominal pain or discomfort not helped by medication, rest, hot water bottle, or heating pad

You should start to feel better each day after the abortion.   Feeling sick including weakness, nausea, abdominal pain or discomfort, vomiting, or diarrhea more than 24 hours after taking misoprostol could be a sign of serious infection.  Contact your clinician right away if you have any of these symptoms.  Do not wait for your follow-up appointment.

You may need another visit with your provider.  Rarely, women need vacuum aspiration or hospitalization.  Take your medication guide with you if you need to visit a clinician who did not give you the medicine.

After the Abortion

It is very important to return for check ups to be sure that the abortion is complete. The first follow-up visit may take place anytime you think you may have passed the tissue, to confirm that the abortion is complete, or if you want to check on your progress. At the follow-up visit another ultrasound examination will be done.

If you are still pregnant after taking the medicine, your clinician will help you decide what to do. You may:

  • wait 2-6 weeks and see if the tissue is expelled
  • take more misoprostol
  • need a surgical abortion

After you take the medicine and before your follow-up exam:

  • Do not take aspirin
  • Do not drink alcohol
  • Do not take anti-coagulant (anti-clotting) drugs

Why Some Women Prefer Medication Abortion

  • No anesthesia or surgery
  • Can be done early
  • They may feel they have more control
  • They may feel it is less invasive
  • They may feel it is more "natural"
  • They may feel it is more like miscarriage
  • They have more privacy
  • They may have the abortion at home
  • There is decreased risk of damage to the uterus

Abortions are safest early in pregnancy. Ninety-seven percent of women in clinical trials would recommend medication abortion to a friend.
