Debate over the abortion pill mifepristone resurfaces after Makary confirmed to head the FDA
Many Americans wonder whether the pill used in most U.S. abortions will be restricted under the new Republican administration in Washington.
President Donald Trumpās pick to lead the Food and Drug Administration, Dr. Marty Makary, was confirmed by the Senate late Tuesday. In recent testimony before the Senate health committee, Makary wouldnāt commit to specific action on the pill, called mifepristone, despite prodding from both Republicans and Democrats.
Medical professionals call it āamong the safest medicationsā ever approved by the FDA. But a Christian conservative group that sued the FDA over the drug says it has caused ātens of thousandsā of āemergency complications."
Hereās what to know about the safety of mifepristone, which is typically used with misoprostol in medication abortions that make up close to two-thirds of abortions in the U.S.
What are the safety limits on use of the abortion pill?
The FDA approved mifepristone in 2000 as a safe and effective way to end early pregnancies. Currently, there are no in-person requirements and the pill can be sent through the mail.
That's not how the FDA first treated mifepristone, which on rare occasions can cause dangerous, excessive bleeding that requires emergency care. Strict safety limits were placed on who could prescribe and distribute it ā only specially certified physicians and only as part of three mandatory in-person appointments with the patient getting the drug. The doctors also had to be capable of performing emergency surgery to stop excess bleeding and an abortion procedure if the drug didnāt end the pregnancy.
Over time, the FDA reaffirmed mifepristoneās safety and repeatedly eased restrictions.
How often are there serious problems?
Abortion opponents say the FDAās 2021 decision allowing online prescribing and mail-order use of mifepristone resulted in many more āemergency complications.ā
But that argument lumps together women experiencing a range of issues ā from mifepristone not working to people who may simply have questions or concerns but donāt require medical care.
OB-GYNs say a tiny fraction of patients suffer āmajorā or āseriousā adverse events after taking mifepristone.
A filed with the Supreme Court last year by a group of medical organizations including the American College of Obstetricians and Gynecologists says: āWhen used in medication abortion, major adverse events ā significant infection, excessive blood loss, or hospitalization ā occur in less than 0.32% of patients, according to a highly regarded study with more than 50,000 patients.ā
The definition that scientists generally use for serious adverse events includes blood transfusions, major surgery, hospital admissions and death, said Ushma Upadhyay, one of the authors of that .
The prescribing information included in the packaging for mifepristone tablets lists slightly different statistics for what it calls āserious adverse reactions.ā It cites ranges for how frequently various complications occur: 0.03% to 0.5% for transfusion; 0.2% for sepsis and 0.04% to 0.6% for hospitalization related to medication abortions. The ranges reflect findings across various relevant studies, experts said.
Why do patients go to the emergency room?
Mifepristoneās labeling lists a complication that most medical groups donāt consider a serious or major adverse event: ER visits, which ranged from 2.9% to 4.6%. The current FDA label lists going to the ER as an option if patients experience prolonged heavy bleeding, severe abdominal pain or a sustained fever. But ER visits donāt always reflect big problems.
Some people may go there after a medication abortion because they want to be checked out or have questions but donāt have a doctor, said Upadhyay, a public health scientist at the University of California, San Francisco. Others, she said, ādonāt want to go to their primary care provider about their abortionā because of stigma.
A in 2018 found that slightly more than half of patients who visited the ER because of abortions received only observational care.
How effective is the pill?
Mifepristone results in a completed abortion 97.4% of the time, according to U.S. studies cited in the FDA label.
But in 2.6% of cases, a surgical intervention is needed. And 0.7% of the time, the pregnancy continues.
Thatās compared to a procedural abortion in a clinic, where the chance of the procedure failing to end a pregnancy āis extremely, extremely low,ā probably less than 0.1%, said Dr. Pratima Gupta, a board member for the American College of Obstetricians and Gynecologists.
āAny time a procedural abortion is done, the clinicians ensure that it was a complete abortionā by examining the tissue that is removed or performing an ultrasound during or after the procedure, she said.
Gupta, who has done abortion procedures for more than 20 years, said there are āvery few complications from abortion ā any kind of abortion, medication or procedural abortion.ā
One suggested thatās just as true for medication abortions that happen in a clinic, a doctorās office or at home with the help of telehealth.
How does mifepristoneās safety and effectiveness compare to other drugs?
The FDA makes drug approval decisions on a case-by-case basis, weighing effectiveness, safety and other factors.
No drug is 100% effective, and many common medications donāt work for a significant portion of patients.
Antidepressants typically help between 40% and 60% of people with depression. New antibiotics approved by the FDA often resolve about 70% of infections.
Since 2000, roughly 6 million patients have taken mifepristone, according to the FDA. A 2021 review of agency records looking for deaths that were likely related to the drug identified 13, or 0.00027% of patients.
Medical organizations supporting mifepristoneās availability say the drugās safety ā given the rate of deaths ā compares to āibuprofen, which more than 30 million Americans take in any given day.ā
