Medication decisions in pregnancy: A balancing act
Experts propose an ethics-based, evidence-backed approach to shared decision-making

Most women use medication during pregnancy. Yet, selecting appropriate drugs and doses is challenging. In a new The Lancet article, physicians and researchers from the Radboud university medical center, Maastricht UMC+, Imperial College London, and the University of Liverpool introduce a shared decision-making approach combining ethical principles and a pregnant woman’s values with existing evidence. They use the example of sertraline, a commonly prescribed antidepressant in pregnancy, to illustrate the advocated decision-making process.
Although pregnant women often need medication, data on drug safety and efficacy in pregnancy remains limited. Historically seen as vulnerable research subjects, pregnant women have been widely excluded from drug development and testing. The thalidomide scandal of the 1950s-60s, which caused severe birth defects in thousands of children, exposed the potential risks of administering medications to pregnant women without adequate evidence, prompting a highly cautious approach to prescribing drugs during pregnancy. However, withholding medication from a pregnant woman may indirectly harm both her and her child by compromising the mother’s health and well-being. Additionally, pregnant women may not receive balanced information about a medication’s risks and benefits or be fully involved in treatment decisions, potentially leading to suboptimal decision-making and avoidable harm.
‘The medical community urgently needs ethical and actionable models to help balance the benefits and risks of medications for individual pregnant patients and fetuses,’ says lead author Charlotte Koldeweij. The article outlines key ethical principles and provides practical steps to assist clinicians and pregnant women in making shared decisions on appropriate drug use and dosage, considering both available evidence and a woman’s personal values. This approach is exemplified for sertraline, an antidepressant that may be prescribed during pregnancy. Promoting the active participation of pregnant women in decisions about their treatment could help shift societal perceptions of their vulnerability and increase their inclusion in medical research, helping to address the current evidence gap.
This work is part of project MADAM (Model Adjusted Doses for All Mothers). In collaboration with the Dutch Teratology Information Service Lareb Moeders van Morgen, which compiles available information on medication safety during pregnancy and breastfeeding, researchers leverage virtual pregnancy models and insights from a multidisciplinary committee of experts and patients to develop tailored dose recommendations for pregnant women and fetuses for widely used medications. The project is supported by a grant from the Bill & Melinda Gates Foundation. ‘Our goal is to establish and promote the use of model-informed, pregnancy-adjusted doses, which requires gaining acceptance from clinicians and pregnant women,’ states project leader Saskia de Wildt.

A low-sugar diet in utero and in the first two years of life can meaningfully reduce the risk of chronic diseases in adulthood, a new study has found, providing compelling new evidence of the lifelong health effects of early-life sugar consumption.
Published in Science, the study finds that children who experienced sugar restrictions during their first 1,000 days after conception had up to 35% lower risk of developing Type 2 diabetes and as much as 20% less risk of hypertension as adults. Low sugar intake by the mother prior to birth was enough to lower risks, but ...

New Orleans - Ochsner Health physicians Dr. Richard Zweifler and Dr. Joseph Tarsia are co-authors on a post hoc analysis carried out in the ARCADIA randomized clinical trial, comparing the effectiveness of apixaban versus aspirin in preventing adverse clinical outcomes in patients with a history of cancer and cryptogenic stroke. The research found no significant difference in the risk of major ischemic and hemorrhagic events between those taking apixaban and aspirin. The ...

Researchers at the University of Arizona’s Mel and Enid Zuckerman College of Public Health received a $1.75 million Centers for Disease Control and Prevention grant to conduct a community-based, participatory research study designed to improve vaccine uptake in Arizona’s rural and border communities.
Vaccination is a highly effective public health intervention that saves millions of lives per year, yet vaccination rates have declined in recent years for a variety of reasons, ranging from safety concerns to religious and philosophical objections.
“Vaccination is a cornerstone of public health,” said co-principal investigator Tomas ...

Macrophage cells are the immune system’s frontline soldiers, early on the scene to protect the body from foreign invaders. These cells answer the immune system's critical question for the rest of its troops: friend or foe?
As critical responders, macrophages can perceive helpful biotechnology as threats. If not created with the right materials or mechanical forces, these devices can trigger an immune response that can cause inflammation, scar tissue or device failure.
But what is the right material or the right mechanical force? In a meta-analysis co-led ...

Beyond colorful coral reefs and diverse nearshore ecosystems, Pacific Ocean waters surrounding the Hawaiian Islands have comparatively little marine life and low biological productivity. New research published by University of Hawai‘i (UH) at Mānoa oceanographers showed that eddies on the leeward side of the Hawaiian Islands can supply nutrients, not only locally, but also to the opposite side of the island chain and stimulate blooms of phytoplankton, microscopic plant life that lives in the surface ocean.
The study, published in JGR Oceans, was selected by the American Geophysical Union’s editorial board as a featured article.

While many people believe that poor sleep during pregnancy is inevitable, new research has determined that cognitive behavioral therapy for insomnia (CBTi) while pregnant can not only improve sleep patterns but also address postpartum depression.
Researchers from UBC’s Okanagan and Vancouver campuses, as well as the University of Calgary, discovered that delivering CBTi during pregnancy significantly reduces postpartum depressive symptoms after a baby arrives.
“Early intervention is crucial for infant and parental mental health,” says Dr. Elizabeth Keys, an Assistant Professor in UBCO’s School of Nursing and a study co-author. “Our research explores how addressing ...
