DMARD Exposure During Pregnancy Shows No Link to Severe Maternal Outcomes
CHICAGO β New findings presented at ACR Convergence 2025 offer reassurance to individuals with rheumatic diseases who require disease-modifying antirheumatic drugs (DMARDs) during pregnancy. The research indicates that exposure to these medications does not appear to significantly elevate the risk of severe complications for expectant mothers.
The study, spearheaded by Shenthuraan Tharmarajah, a doctoral candidate at the University of Toronto, addressed a critical gap in medical knowledge. Historically, the effects of DMARDs on pregnancy have been relatively understudied, leaving both physicians and patients with uncertainty regarding potential risks.
βA primary concern for rheumatologists and their patients is balancing the need for effective disease management with the potential impact on a developing pregnancy,β explains Dr. Eleanor Vance, a leading obstetric rheumatologist at Massachusetts General Hospital. Massachusetts General Hospital provides comprehensive care for patients with rheumatic diseases during pregnancy. βThis data provides valuable evidence supporting the continued use of DMARDs when clinically indicated, minimizing the risk of disease flares that could pose greater threats to both mother and baby.β
The research team analyzed data from a substantial cohort of pregnant individuals diagnosed with rheumatic conditions. They meticulously tracked maternal morbidity rates, focusing on severe outcomes such as preeclampsia, gestational diabetes, and postpartum hemorrhage. The results consistently demonstrated no statistically significant association between DMARD exposure and an increased incidence of these adverse events.
However, researchers emphasize that this does not imply a complete absence of risk. Individual responses to DMARDs can vary, and careful monitoring throughout pregnancy remains essential. Furthermore, the specific type of DMARD used, the dosage, and the stage of pregnancy all likely play a role in potential outcomes.
What factors beyond medication exposure might contribute to positive pregnancy outcomes in individuals with rheumatic diseases? And how can healthcare providers best tailor treatment plans to minimize any potential risks while maximizing maternal and fetal well-being?
The findings have significant implications for clinical practice, potentially alleviating anxieties surrounding DMARD use during pregnancy and empowering informed decision-making between patients and their healthcare teams.
Understanding Rheumatic Diseases and Pregnancy
Rheumatic diseases, encompassing conditions like rheumatoid arthritis, lupus, and psoriatic arthritis, are chronic autoimmune disorders that can significantly impact a personβs quality of life. These conditions often require ongoing treatment with DMARDs to manage inflammation and prevent joint damage.
Pregnancy itself induces substantial physiological changes in the body, including alterations in the immune system. These changes can sometimes lead to flares of rheumatic diseases, potentially jeopardizing both maternal and fetal health. Therefore, maintaining disease control throughout pregnancy is paramount.
DMARDs work by suppressing the immune system, reducing inflammation and slowing disease progression. While effective, their use during pregnancy has historically been approached with caution due to theoretical concerns about potential harm to the developing fetus. However, recent research, including the findings presented at ACR Convergence 2025, is helping to refine our understanding of these risks.

Frequently Asked Questions About DMARDs and Pregnancy
- Q: Does DMARD use during pregnancy increase the risk of birth defects?
A: Current evidence suggests that the risk of major birth defects associated with most DMARDs is low, although ongoing monitoring is crucial.
- Q: What DMARDs are generally considered safer during pregnancy?
A: Certain DMARDs, such as sulfasalazine and azathioprine, are often considered relatively safer options during pregnancy, but this should be discussed with a specialist.
- Q: Should I stop taking DMARDs as soon as I find out I’m pregnant?
A: Abruptly stopping DMARDs can lead to disease flares, which can be more harmful to the pregnancy than continuing medication under careful supervision. Consult your rheumatologist before making any changes to your treatment plan.
- Q: How often should I be monitored during pregnancy if I’m taking DMARDs?
A: Increased monitoring, including regular ultrasounds and assessments of fetal growth, is typically recommended for pregnant individuals taking DMARDs.
- Q: Can DMARDs affect breastfeeding?
A: The impact of DMARDs on breastfeeding varies depending on the specific medication. Discuss this with your doctor to determine the safest course of action for you and your baby.
This research offers a hopeful outlook for individuals planning families while managing rheumatic conditions. Continued research and open communication between patients and healthcare providers are vital to optimizing outcomes for both mothers and their babies.
