On March 29, 2016, the U.S. Food and Drug Administration (FDA) approved updated labeling for mifepristone (also known as the abortion pill or by its brand name, Mifeprex®), which is prescribed along with another medication, misoprostol, for medication abortion in the United States. The FDA’s move to change the label is important in many ways. Although off-label use of drugs is generally accepted in the United States, many clinicians see FDA labels as guides to appropriate and legally defensible clinical practice. First and foremost, the label update reaffirms that medication abortion is very safe and highly effective. It also has the potential to increase access to medication abortion in this country.

An Update Based On Evidence And Clinical Practice

Scientists and medical providers have been conducting studies of alternate medication abortion regimens since before Mifeprex® was approved in 2000. Since its approval, many physicians have prescribed Mifeprex® according to the regimen in the updated label, so the label is now aligned with standard medical practice, which has been proven safe and effective. Over the past 15 years, it has been used in more than 2.75 million abortions in the United States, and serious complications have been extremely rare.

One of the most significant changes to the mifepristone label is an increase in eligibility from 49 days’ to 70 days’ gestation. This change is supported by substantial evidence demonstrating that the mifepristone/misoprostol regimen is safe and effective through the 10th week of gestation. This change has significant implications for access to medication abortion: Under the original protocol, just 37 percent of all U.S. abortions were eligible for mifepristone, but as a result of the updated protocol, the proportion of all abortions now eligible has doubled to 75 percent.

Some of the key changes to the mifepristone label include:

Old LabelingNew Labeling
Use through 49 days' gestationUse through 70 days' gestation
Day 1: Mifepristone 600 mg (3 tablets) orallyDay 1: Mifepristone 200 mg (1 tablet) orally
Day 3: Misoprostol 400 µg (2 tablets) orally at healthcare provider facility24-48 hours after mifepristone dose: Misoprostol 800 µg (4 tablets) buccally (placed in the cheek); home administration allowed
Post-treatment examination: Patients return to provider 14 days after taking mifepristonePost-treatment assessment: Patients are assessed 7-14 days after taking mifepristone; not necessarily an in-person clinic visit
Prescriber: By or under the supervision of a physician who is authorized to prescribe the drugPrescriber: By or under the supervision of a healthcare provider who is authorized to prescribe the drug

Improving Access To Medication Abortion

In addition to increasing eligibility for medication abortion, the mifepristone label update will likely strengthen an existing trend towards earlier abortions. According to data from the Centers for Disease Control and Prevention, the timing of abortions has shifted to earlier in the first trimester over the past decade, likely due in part to the availability of medication abortion. Additionally, although the overall number of abortions in the U.S. has been declining since the 1990s, the share of abortions performed using medication has increased, from 6 percent of all abortions in 2001 (one year after mifepristone was approved) to 23 percent of abortions in 2011 (the most recent year for which data are available).

Other mifepristone label updates also reduce barriers to medication abortion. In particular, the changes make the procedure more affordable. A regimen involving one mifepristone tablet is substantially less expensive than one involving three. Additionally, because the label allows a woman to take misoprostol at home and to follow up with her provider over the phone, rather than in person, she will have to make fewer trips to the clinic. The updated label also allows mid-level providers—such as nurse midwives, nurse practitioners, and physician assistants—to administer medication abortion, which could increase access to this safe and effective procedure.

Legal Barriers To Medication Abortion

Over the last several years, antiabortion state legislators have enacted a wave of provisions hostile to medication abortion. Counter to the updated mifepristone label, 37 states allow only physicians to provide medication abortion. In these states, a woman seeking an abortion may have a longer wait time for an appointment or have to travel further to reach a clinic attended by a physician. Provisions that require in-person counseling prior to taking mifepristone, which exist in 13 states, and other requirements that necessitate multiple trips to the clinic pose further barriers to medication abortion. If these unnecessary restrictions were removed, they would increase access to abortion, including early medication abortion.

In an effort to reach rural women or women living in cities without an abortion provider, some providers began offering medication abortion services via telemedicine. Telemedicine allows a physician at a remote site to provide the screening and counseling for mifepristone via a computer, and press a button that allows a cash-register type drawer containing a single dose of mifepristone to be opened at the patient’s location. Telemedicine provision of medication abortion has been found to be safe, effective, and acceptable to women — and improves access to early abortion. Yet, 18 states prohibit the use of telemedicine for medication abortion by requiring that the clinician providing a medication abortion physically present the pill to the patient, thereby limiting access.

In addition, North Dakota, Ohio, and Texas require that mifepristone be provided in accordance with the FDA-approved label. In these states, the updated label will likely improve current access to medication abortion; however, these state laws do not allow for additional improvements in practice if further advances are made to the medication abortion regimen. For example, research has found mifepristone to be effective in facilitating some second-trimester abortion procedures, but these practices will not be permitted in these states. Similarly, if research uncovers further improvements to the early medication abortion regimen, these state laws will prevent implementation of those improvements to medical practice.

The FDA’s decision to update the mifepristone label will help ensure that individuals seeking abortion have easy, safe access to a medication option. In turn, the label change is a validation of clinical research showing that this protocol is safe, effective, and medically sound.
