Q. I heard there is a new pill that can induce abortion so that a surgical abortion is no longer necessary. Is this true? Is it safe to use? Can I take it home?
A. There are two different types of drug therapies that can terminate pregnancy; one is available in the United States and one is not. In my opinion, at this time, neither therapy is better than conventional surgical abortion. RU 486, the so-called abortion pill, is widely used in France. When combined with oral Prostaglandins (substances that cause the uterus to contract) RU 486 can induce abortion up to the ninth week of pregnancy. As of this writing, however, RU 486 is not legal in the United States; therefore, it is not an option for American women. Anti-abortion forces have so far been effective in their efforts to block the use of RU 486 as an abortion drug, and it is only available in the United States to medical researchers for experimental purposes. Recent studies have suggested that RU 486 may be an effective treatment against breast cancer and other diseases, and a handful of American scientists are conducting further research.
There is another drug regimen for abortion that is both legal and available in the United States, but it’s very new and somewhat controversial. According to a study published in the New England Journal of Medicine, two other drugs commonly prescribed for other purposes can, when combined, also safety and effectively terminate pregnancy up to nine weeks.
- The first drug, methotrexate, is approved by the Food and Drug Administration (FDA) to treat some cancers as well as rheumatoid arthritis and psoriasis.
- The second drug, Misoprostol, is an approved anti-ulcer medication that can also cause uterine contractions.
For the past decade, methotrexate has been prescribed “off label” (not for its approved use) to terminate ectopic pregnancies (a potentially life-threatening condition that occurs when the fertilized egg lodges within the fallopian tube). Misoprostol is also commonly prescribed “off label” to soften the cervix when inducing labor.
In order to induce abortion, the patient must be given a shot of methotrexate, which terminates the pregnancy in two ways: it interferes with the growth of the embryo in the placenta by killing rapidly-dividing cells, and it also blocks the action of folic acid, an important B vitamin that is critical to the normal growth and development of the embryo. Five to seven days later, the patient must return to the doctor for a vaginal suppository containing Misoprostol. Typically, within two days after getting the suppository, the woman will begin to bleed and cramp, as she would with a miscarriage. In rare cases, the pregnancy may not terminate, and a surgical abortion is required.
There are some advantages to this new abortion procedure over surgical abortions. For one thing, it can be performed in any doctor’s office and does not necessitate a hospital stay or visit to an abortion clinic, which many women may find upsetting (particularly if anti-abortion people are picketing outside). For another, unlike a surgical abortion, which is best performed at around six weeks, the drug-induced abortion can be performed as soon as the woman knows she is pregnant, which eliminates the days or weeks of waiting.
There are some disadvantages, however, to this procedure that women should be aware of. First, the drug-induced abortion takes considerably longer than the usual surgical procedure. During the first twelve weeks of pregnancy, abortion is usually done by vacuum aspiration, which takes between 10 and 15 minutes. In this procedure, the cervix at the entrance of the uterus is dilated and a blunt-tipped tube is placed in the uterus. The tube is connected to a small suction machine which draws out the contents of the uterus. Vacuum aspiration can be performed with either local or general anesthetic. In most cases, after an hour or two of rest, the woman can go home. Although there may be some residual bleeding for up to two weeks, the abortion is over quickly and efficiently. On the other hand, the drug-induced abortion can take up to two weeks before the abortion is finalized, which can be emotionally wrenching for many women. In addition, if unprepared, many women may be very distressed by the amount of bleeding and cramping, although most of the women who have had this procedure find out the pain is easily controlled with medication. In addition, since neither methotrexate nor Misoprostol have been approved by the FDA for use for abortion, some doctors may be reluctant to administer them for this purpose. As of now, I personally would not recommend this procedure until it has been tested further.

Marianne J. Legato, MD, Ph. D. (hon. c.), FACP is an internationally renowned academic, physician, author, lecturer, and pioneer in the field of gender-specific medicine. She is a Professor Emerita of Clinical Medicine at Columbia University College of Physicians & Surgeons and an Adjunct Professor of Medicine at Johns Hopkins Medical School. Dr. Legato is also the Director of the Foundation for Gender-Specific Medicine, which she founded in 2006 as a continuation of her work with The Partnership for Gender-Specific Medicine at Columbia University. She received an honorary PhD from the University of Panama in 2015 for her work on the differences between men and women.
At its core, gender-specific medicine is the science of how normal human biology differs between men and women and how the diagnosis and treatment of disease differs as a function of gender. Dr. Legato’s discoveries and those of her colleagues have led to a personalization of medicine that assists doctors worldwide in understanding the difference in normal function of men and women and in their sex-specific experiences of the same diseases.
She began her work in gender-specific medicine by authoring the first book on women and heart disease, The Female Heart: The Truth About Women and Coronary Artery Disease, which won the Blakeslee Award of the American Heart Association in 1992. Because of this research, the cardiovascular community began to include women in clinical trials affirming the fact that the risk factors, symptoms, and treatment of the same disease can be significantly different between the sexes. Convinced that the sex-specific differences in coronary artery disease were not unique, Dr. Legato began a wide-ranging survey of all medical specialties and in 2004, published the first textbook on gender-specific medicine, The Principles of Gender-Specific Medicine. The second edition appeared in 2010 and the third edition, dedicated to explaining how gender impacts biomedical investigation in the genomic era, won the PROSE Award in Clinical Medicine from the Association of American Publishers in 2018. A fourth edition is forthcoming.
She also founded the first scientific journals publishing new studies in the field, The Journal of Gender-Specific Medicine, and a newer version, Gender Medicine, both listed in the Index Medicus of the National Library of Medicine. She has founded a third peer-reviewed, open access journal, Gender and the Genome, which focuses on the impact of biological sex on technology and its effects on human life.
Dr. Legato is the author of multiple works, including: What Women Need to Know (Simon & Schuster, 1997), Eve’s Rib (Harmony Books, 2002), Why Men Never Remember and Women Never Forget (Rodale, 2005), Why Men Die First (Palgrave, 2008), The International Society for Gender Medicine: History and Highlights (Academic Press, 2017), and most recently, The Plasticity of Sex (Academic Press, 2020). Her books have been translated into 28 languages to date.
As an internationally respected authority on gender medicine, Dr. Legato has chaired symposia and made keynote addresses to world congresses in gender-specific medicine in Berlin, Israel, Italy, Japan, Panama, South Korea, Stockholm, and Vienna. In collaboration with the Menarini Foundation, she is co-chairing a symposium on epigenetics, Sex, Gender and Epigenetics: From Molecule to Bedside, to be held in Spring 2021 in Italy. She maintains one of the only gender-specific private practice in New York City, and she has earned recognition as one of the “Top Doctors in New York.”
