ACOG Issues First Formal Guidance on GLP-1 Use During Pregnancy

Guidance on GLP-1 Use Before and After Pregnancy

The rise of GLP-1 medications has created a clinical gray zone for pregnancy, prompting the American College of Obstetricians and Gynecologists to issue its first-ever formal guidance on the topic, NPR reported.

While the drugs can boost fertility for some patients, leading to both planned and unplanned pregnancies, doctors advise stopping them beforehand.

If patients use a GLP-1 medication, the guidance recommends stopping it one to two months before trying to conceive. This washout period ensures complete drug clearance before fetal organogenesis begins. Doctors also advise avoiding the medications entirely during pregnancy.

GLP-1 Exposure Does Not Increase Maternal Pregnancy Complications

Recent high-quality evidence provides reassurance regarding maternal pregnancy complications following early drug exposure. Researchers evaluated maternal outcomes among thousands of women exposed to GLP-1 therapies around conception. Systematic reviews examined major obstetric complications, including gestational diabetes, preterm delivery rates, and hypertensive disorders of pregnancy.

Exposure to these therapies did not alter overall preterm delivery rates. The odds of preeclampsia and hypertensive disorders remained comparable to unexposed control patients. Exploratory sensitivity analyses even suggested a possible protective effect against gestational diabetes, though observational studies still feature confounding factors such as maternal body mass index.

Experts Advise Avoiding GLP-1 Drugs While Breastfeeding

Regarding breastfeeding and GLP-1 use, ABC News Medical Contributor Dr. Darian Sutton said that providers ideally recommend avoiding the drugs for the first month of the baby’s life. After that period, use can be considered following a discussion with a doctor about risks and benefits. Oral GLP-1 medications carry stricter recommendations due to an additional ingredient that might affect absorption, and experts advise avoiding them during the entirety of breastfeeding.

A recent study found that GLP-1 use is growing among pregnant women and new moms, which led the American College of Obstetricians and Gynecologists to establish formal guidance on the matter. When patients conceive while taking a GLP-1 receptor agonist, clinicians should immediately discontinue the medication and transition the patient to standard obstetric management.

Do GLP-1 medications increase the risk of gestational diabetes or preeclampsia?
Current meta-analyses show no significant rise in gestational diabetes, preeclampsia, or pregnancy hypertension following early exposure.

How long before conception should patients stop taking these drugs?
Most international guidelines advise discontinuing GLP-1 receptor agonists one to two months before conception to allow for complete drug clearance.

What are the recommendations for using oral GLP-1s while nursing?
Medical contributors recommend avoiding oral formulations during the entirety of breastfeeding because an additional ingredient might affect absorption.
