Abortion access

Non-surgical, medically induced, abortions
using methotrexate and misoprostol

Overview:

Medically induced abortions involve the use of a medication instead of surgical techniques.

Religious and social conservatives often refer to medical abortions as "chemical abortions."

Abortions have traditionally involved surgery, clinics, hospitals, insurance companies, instruments, anesthetics, etc. But two recent medical developments may change this in the near future for many women:

Methotrexate is approved by the FDA as an anti-cancer and immune modulator drug. Misoprostol is used to prevent ulcers in patients treated with nonsteroidal antiinflammatory drugs. In 2000-OCT, the manufacturer of misoprostol sent a circular letter which mentioned that the FDA had not approved its use on pregnant women. ₁₆ However, the FDA allows physicians to employ these drugs to induce an abortion, even though that was not their original intent. Obstetricians have used the drug since 1988 to terminate ectopic pregnancies. (Ectopic pregnancies occur when the fertilized ovum lodges in the fallopian tubes. They are sometimes called "tubal pregnancies." If untreated, they are generally life threatening.) ₆

An office of Planned Parenthood reports that "More that 3,000 women have used this method in clinical trials, clinics, and doctors' offices, and there have been no reports of significant side-effects or long-term risks." ₅

A woman who has had unprotected sex can check whether she is pregnant within two weeks of the possible conception, and terminate any pregnancy immediately with help from any cooperating physician. One physician refers to these as "Early Medical Abortions (6-7 weeks) Option using Methotrexate and Misoprostol." ₄

Three women from Seattle who have had medical abortions describe their experience in Reference 13.

In late 1999-DEC, Rhode Island became the last state to pass legislation that approves of the use of Methotrexate & Misoprostol. The treatment is thus legally available across the country. 

What a medical abortion involves:

Methotrexate has been available for almost 50 years as a treatment for tumors, arthritis, and psoriasis. It is given by injection. Normal side effects are described as "usually mild" and not of long duration; they can include: nausea, diarrhea, abdominal cramping, hot flashes, or sores in the mouth. The medication stops the development of the embryo.

Misoprostol is a commonly used prostaglandin medication for ulcers. It is inserted into the vagina, often by the woman at home, 5 to 7 days after the injection of methotrexate. A number of side-effects are possible, including nausea, vomiting, diarrhea, abdominal pain, dizziness, and/or fever and chills.

Methotrexate prevents the cells in the embryo from dividing. Misoprostol causes the womb to contract. Cramping and bleeding will be experienced. Blood clots will be passed. The embryo is usually expelled within a week. If the woman has determined that she is pregnant 2 weeks after conception, and goes immediately to her doctor for the injection, then the development of the embryo might be stopped at 2 weeks, when it is an small piece of undifferentiated tissue. At 3 weeks, it is typically 1/12" (2 mm) long, the size of a pencil point. It most closely resembles a worm; it is long and thin and with a segmented end. A week later, it is typically about 1/5" (5 mm) long. It looks something like a tadpole. The structure that will develop into a head is visible, as is a noticeable tail. The embryo has structures like the gills of a fish in the area that will later develop into a throat.

One complication of this procedure is that it is only about 95% reliable; the embryo is sometimes not expelled, but continues to grow. Because of the nature of the medication used, it will be almost certainly seriously deformed. Before proceeding with a medical abortion, the woman should be willing to follow up with a surgical abortion if the chemical technique fails. One study expresses concern that a small percentage of women may change their mind and not follow through with a surgical abortion in the event that a medical abortion fails. Very serious limb damage in the newborn will result. ₃

Planned Parenthood reports: "The most common complication of a medical abortion, like the most common complication of miscarriage, is heavy bleeding. A small number of women may even need an emergency D&C to stop the bleeding. In very rare cases, a woman may need a blood transfusion." ₅

Published studies by other medical researchers have found that using methotrexate and misoprostol in terminating pregnancies is approximately 90% effective when it is taken up to 49 days from the first day of a woman's last menstrual period.

Results of a Clinical Trial:

Richard U. Hausknecht reported the results of a study at Mount Sinai School of Medicine, New York, NY.

"A total of 171 of the 178 women enrolled in the study (96 percent) had successful medical abortions. Twenty-five women (14 percent) did not have an abortion after the first dose of misoprostol and received a second dose. Eighteen subsequently had complete abortions, but seven required suction curettage. In all seven women who required suction curettage, there was histologic evidence of disruption in the conceptus. No important side effects or complications were noted."

A second study by Dr. Eric Schaff was held at the University of Rochester. They "found that 98 of 100 women completed abortions with the Methotrexate-Misoprostol combination". ₉

Some advantages/disadvantages to medical abortions:

When compared to other methods, advantages include:

Disadvantages include:

One source predicts that the Methotrexate/Misoprostol combination will be eventually replaced with a Mifepristone (RU486)/Misoprostol procedure when RU486 is finally made available. The latter is faster, and has a proven safety history. "Over 200,000 women already have successfully used the Mifepristone regimen." ₉ In Canada, a series of studies across the country started in mid-2000; both medications are being compared.
