Levonorgestrel in cases of rape: How does it work?

Catholic Hospitals Should Permit Physicians to Provide Emergency Contraception to Rape Victims as an Act of Conscientious Provision

While many Catholic hospitals permit the prescription of the emergency contraception drug levonorgestrel for rape victims, some continue to prohibit this practice as a matter of institutional conscience. While the standard approach to this issue has been to offer an argument that levonorgestrel either is or is not morally permissible, we have taken a different tack. We begin by briefly describing and acknowledging that reasonable disagreement exists on this question (part one), and then arguing that the reasonable disagreement itself can serve as a compelling basis for Catholic leadership at hospitals that prohibit emergency contraception for rape victims to accommodate physicians who wish to provide levonorgestrel as a matter of conscience (part two). We end by anticipating and responding to some objections.

Emergency Contraception: Access and Challenges at Times of Uncertainty

BACKGROUND

The UN Commission on Life-Saving Commodities for Women's and Children's Health identified emergency contraceptive pills as 1 of the 13 essential underused, low-cost, and high-impact commodities that could save the lives of millions of women and children worldwide. In the US, 2 emergency contraceptive regimens are currently approved, and their most plausible mechanism of action involves delaying and/or inhibiting ovulation.

AREAS OF UNCERTAINTY

Abortion and contraception are recognized as essential components of reproductive health care. In the US, in the wake of the Dobbs v. Jackson Women's Health Organization Supreme Court decision on June 24, 2022, 26 states began to or are expected to severely restrict abortion. It is anticipated that these restrictions will increase the demand for emergency contraception (EC). Several obstacles to EC access have been described, and these include cost, hurdles to over-the-counter purchase, low awareness, myths about their mechanisms of action, widespread misinformation, and barriers that special populations face in accessing them. The politicization of EC is a major factor limiting access. Improving sex education and health literacy, along with eHealth literacy, are important initiatives to improve EC uptake and access.

THERAPEUTIC ADVANCES

A randomized noninferiority trial showed that the 52 mg levonorgestrel intrauterine device was noninferior to the copper intrauterine device when used as an EC method in the first 5 days after unprotected intercourse. This is a promising and highly effective emergency contraceptive option, particularly for overweight and obese patients, and a contraceptive option with a different bleeding profile than the copper intrauterine device.

CONCLUSIONS

EC represents an important facet of medicine and public health. The 2 medical regimens currently approved in the US are very effective, have virtually no medical contraindications, and novel formulations are actively being investigated to make them more convenient and effective for all patient populations. Barriers to accessing EC, including the widespread presence of contraception deserts, threaten to broaden and accentuate the already existing inequities and disparities in society, at a time when they have reached the dimensions of a public health crisis.

Clinical Pharmacology of Hormonal Emergency Contraceptive Pills

Emergency contraceptives play a major role in preventing unwanted pregnancy. The use of emergency contraceptives is characterized by myths and lack of knowledge by both health professionals and users. The main objective of this paper is to summarize the clinical pharmacology of hormonal methods of emergency contraception. A literature review was done to describe in detail the mechanism of action, efficacy, pharmacokinetics, safety profile, and drug interactions of hormonal emergency contraceptive pills. This information is useful to healthcare professionals and users to fully understand how hormonal emergency contraceptive methods work.

Appreciation for Analysis of how Levonorgestrel Works and Reservations with the use of Meloxicam as Emergency Contraception

This paper is a response to Dr. Kathleen Raviele's recent article on her critical analysis of the use of levonorgestrel given to women postsexual assault and her suggestion that the use of Meloxicam may be an ethical alternative.

Physicians' information to patients and prescription of the emergency contraceptive pill according to their personal experience of using the method and perception of its mechanism of action

OBJECTIVES

The aim of the study was to evaluate the association between physicians' understanding of the mechanism of action of the emergency contraceptive pill (ECP), their personal use of it, and their practice in informing their patients about the method and in prescribing it.

METHODS

The study was carried out in a sample of 3337 obstetrician-gynaecologists who responded to a mailed questionnaire. Bivariate analysis was used to test the association between physicians' personal use of the ECP, their understanding of its mechanism of action, and their practice in informing their patients about the method and in prescribing it. Multiple Poisson regression analysis was carried out to identify variables independently associated with the two dependent variables.

RESULTS

Multiple regression analysis showed that the percentage of physicians who had informed their patients about the ECP was significantly lower among those who had needed it themselves but had not used it and among those living in the northeast of Brazil. A significantly higher percentage of female than male physicians had provided information on the ECP. The percentage of physicians who had prescribed the ECP was significantly lower among those who had needed it themselves but had not used it and among those who believed that it caused a mini-abortion. The proportion of physicians who had ever-prescribed the ECP was greater among those who worked exclusively in private practice and among those who worked in a state capital.

CONCLUSIONS

The misconception that emergency contraception could cause a mini-abortion was associated with its denial to potential users, while physicians' personal experience of needing to use it favoured the likelihood of their informing potential users about it and prescribing it.

Mechanism of action of levonorgestrel emergency contraception

There has been much debate regarding levonorgestrel emergency contraception's (LNG-EC's) method of action since 1999 when the Food and Drug Administration first approved its use. Proponents of LNG-EC have argued that they have moral certitude that LNG-EC works via a non-abortifacient mechanism of action, and claim that all the major scientific and medical data consistently support this hypothesis. However, newer medical data serve to undermine the consistency of the non-abortifacient hypothesis and instead support the hypothesis that preovulatory administration of LNG-EC has significant potential to work via abortion. The implications of the newer data have important ramifications for medical personnel, patients, and both Catholic and non-Catholic emergency room protocols. In the future, technology such as the use of early pregnancy factor may have the potential to quantify how frequently preovulatory LNG-EC works via abortion. Lay Summary: How Plan B (levonorgestrel emergency contraception) works has been vigorously debated ever since the Food and Drug Administration approved it in 1999. Many doctors and researchers claim that it has either no-or at most-an extremely small chance of working via abortion. However, the latest scientific and medical evidence now demonstrates that levonorgestrel emergency contraception theoretically works via abortion quite often. The implications of the newer data have important ramifications for medical personnel, patients, and both Catholic and non-Catholic emergency room rape protocols.
