Since evidence shows that medication abortion is extremely safe, why is mifepristone so restricted? And should it be? Mifepristone, used with misoprostol for medication abortion for pregnancies up to 10 weeks’ gestation, is highly regulated in the United States. Going back to 2000, when the Food and Drug Administration approved Mifeprex (brand name of mifepristone), its access was restricted under the FDA Risk Evaluation and Mitigation Strategy (REMS).

REMS is an FDA drug safety program, where certain medications with serious safety concerns are subject to restrictions intended to ensure that the benefits of the medication outweigh its risks. For example, the drug vigabatrin, with a side effect of permanent vision loss, is used to treat epilepsy. The REMS for vigabatrin requires counseling on the risk of vision loss and periodic vision monitoring.

The FDA claims that rare side effects of mifepristone – heavy vaginal bleeding, severe infection, and incomplete abortion – are risks that warrant the REMS, despite the known safety of medication abortion, with less than 1% of patients requiring emergency intervention for heavy vaginal bleeding or infection. The mifepristone REMS requires that the drug is dispensed in a hospital, clinic or medical office by a certified health care provider and not in a pharmacy as is the case with most prescribed medications, and that patients must read and sign the patient agreement form in the physical presence of the dispensing physician and may not receive counseling via telemedicine, for example.

Since FDA approval over 20 years ago, much evidence shows that the REMS is unnecessary and creates a major obstacle to access. Many clinicians cannot meet the REMS requirements. Many women must travel great distances to obtain mifepristone or delay their abortion past the acceptable gestational age for medication abortion.

In spring 2020, at the onset of the COVID-19 pandemic, the Centers for Disease Control and Prevention issued general guidance recommending use of telemedicine to limit in-person medical visits to reduce risk of exposure to the SARS-CoV-2 virus, and to ensure access to medication abortion, the ACLU filed a federal lawsuit against the FDA to suspend the requirement for in-person mifepristone dispensing. In July 2020, a Maryland District Judge granted a preliminary injunction, preventing the FDA from enforcing the in-person dispensing requirement for the duration of the declared public health emergency, allowing telemedicine medication abortion using mail or delivery service for administration of mifepristone. All other REMS requirements remained in effect.

In January 2021, the FDA appealed, seeking to reinstate the REMS. The U.S. Supreme Court, with its conservative majority, ruled to reimpose the REMS. Following this decision, a large coalition of reproductive rights groups petitioned the Biden administration to suspend the mifepristone in-person requirement during the public health emergency of the pandemic. In April 2021, the FDA announced it would use discretion and cease to enforce the in-person dispensing requirement throughout the remainder of the public health emergency.

We applaud the FDA for doing the right thing, taking the advice of numerous scientific and advocacy groups to expand access to mifepristone by at least temporarily nullifying unnecessary and burdensome restrictions that disproportionately affect people of color; young people; and people who live in rural areas, have lower incomes, and/or who are undocumented. We join the voices of numerous colleagues and organizations, including the American College of Obstetricians and Gynecologists, our premier women’s health organization, in calling for a permanent end to the mifepristone REMS.

EXPERT COMMENTARY

Most US women aged 15 to 49 currently use contraception, with long-acting reversible contraception (LARC)—IUDs and the contraceptive implant—increasing in popularity over the last decade.¹ Oral contraceptive pills, male condoms, and LARC are the most common reversible methods used.¹ While the efficacy and safety of contraception have been established, few studies have examined the effect of recent contraceptive use on fertility.

Fecundability is the probability of pregnancy during a single menstrual cycle for a couple engaging in regular intercourse and not using contraception.² Small studies have found short-term reductions in fecundability after discontinuing combined oral contraceptives and larger reductions after stopping injectable contraceptives, with no long-term differences among methods.^3,4

Data are limited regarding the effects of other forms of contraception on fecundability, particularly LARC methods. A recent study was designed to evaluate the association between the last contraceptive method used and subsequent fecundability.²

Details of the study

Yland and colleagues pooled data from 3 prospective cohort studies of 17,954 women planning pregnancies in Denmark, Canada, and the United States. Participants reported the contraceptive method used most recently before trying to conceive. They completed questionnaires every 2 months for 12 months or until they reported a pregnancy. Women were excluded if they tried to conceive for more than 6 menstrual cycles at study entry.

The authors calculated the fecundability ratio—the average probability of conception per cycle for a specific contraceptive method compared with a reference method—using proportional probability models adjusted for potential confounders. They also calculated pregnancy attempt time using participant-reported menstrual cycle length and date of last menstrual period during follow-up questionnaires.

After adjusting for personal factors, medical history, lifestyle characteristics, and indicators of underlying fertility, the authors found that injectable contraceptive use was associated with decreased fecundability compared with barrier method use (fecundability ratio [FR], 0.65; 95% confidence interval [CI], 0.47–0.89). Hormonal IUD use was associated with slight increases in fecundability compared with barrier method use (FR, 1.14; 95% CI, 1.07–1.22) and copper IUD use (FR, 1.18; 95% CI, 1.05–1.33). All other contraceptive methods were not significantly different from barrier methods.

LARC method use was associated with the shortest delay in return of normal fertility (2 cycles), followed by oral and ring contraceptives (3 cycles) and patch (4 cycles). Women using injectable contraceptives experienced the longest delay (5–8 menstrual cycles). Lifetime duration of contraceptive use did not impact fecundability in the North American cohort.

Study strengths and limitations

This large, prospective study contributes useful information about fecundability after stopping contraceptive methods. It confirms earlier studies’ findings that showed decreased fecundability after stopping injectable contraceptives. Study participants’ most recent method used was similar to overall US method distribution.¹

Study limitations include online recruitment of self-selecting participants, which introduces selection bias. The study population was overwhelmingly white (92%) and highly educated (70% with college degrees), quite different from the US population. These findings may therefore have limited generalizability. Additionally, injectable contraceptive users had higher body mass index and were more likely to smoke and have diabetes, infertility, or irregular menstrual cycles. IUD users were more likely to be parous and have a history of unplanned pregnancy, indicating possible higher baseline fertility. Even after adjusting, possible unmeasured factors could impact study results. ●
