Ozempic and Pregnancy: What Every Expectant Mother Should Know
As an expectant mother, you’re likely aware of the importance of managing your health during pregnancy. One aspect that might be on your mind is Ozempic and pregnancy.
This medication, containing semaglutide, has gained attention for its role in blood sugar control and weight management. However, its use during pregnancy raises important questions about potential risks and benefits.
You may be wondering about the safety of Ozempic during pregnancy or its effects on fertility. This article will explore the connection between Ozempic and pregnancy risks, including miscarriage and birth defects.
We’ll also look at FDA warnings, the need for a pregnancy registry, and alternatives for managing gestational diabetes.
Additionally, we’ll touch on topics like macrosomia, preterm delivery, and whether you can take Ozempic while breastfeeding, to give you a complete picture of what you need to know.
Understanding Ozempic and Its Effects
What is Ozempic?
Ozempic is a prescription medication containing semaglutide, which belongs to a class of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists. The U.S. Food and Drug Administration (FDA) approved Ozempic in 2017 for adults with type 2 diabetes.
It’s designed to improve blood sugar control when used alongside diet and exercise.
Ozempic is administered as a once-weekly injectable medication. It’s important to note that while Ozempic may lead to weight loss, it’s not primarily a weight loss drug.
Its main purpose is to manage blood sugar levels in people with type 2 diabetes.
How Ozempic works
Ozempic works by mimicking the action of GLP-1, a hormone naturally produced in your body. When you eat, GLP-1 has several effects that help regulate blood sugar:
- It stimulates the release of insulin from your pancreas. Insulin helps move glucose from your bloodstream into your cells, where it’s used for energy.
- It reduces the production of glucagon, another hormone that raises blood sugar levels.
- It slows down the emptying of your stomach, which helps you feel full for a longer time.
By imitating GLP-1, Ozempic has these same effects on your body. This leads to better blood sugar control and can also result in reduced appetite and weight loss.
One key feature of Ozempic is its long-lasting effect. While natural GLP-1 breaks down quickly in the body, Ozempic has been designed to resist degradation.
This means it can remain active in your body for about a week, allowing for once-weekly dosing.
Approved uses of Ozempic
The FDA has approved Ozempic for two main uses in adults with type 2 diabetes:
- To improve blood sugar control: Ozempic can be used along with diet and exercise to help manage blood glucose levels in adults with type 2 diabetes.
- To reduce cardiovascular risks: For adults with type 2 diabetes and known heart disease, Ozempic is approved to lower the risk of major cardiovascular events such as heart attack, stroke, or death.
It’s worth noting that Ozempic is not approved for use in people with type 1 diabetes. Also, while weight loss can be a side effect of Ozempic, it’s not officially approved as a weight loss medication.
However, a higher-dose version of semaglutide, marketed under the brand name Wegovy, has been approved specifically for chronic weight management in adults with obesity or overweight with at least one weight-related condition.
When prescribed Ozempic, you’ll typically start with a lower dose, which may be increased over time based on your body’s response and any side effects you experience. Your healthcare provider will work with you to find the right dose to manage your blood sugar effectively.
While Ozempic can be an effective tool for managing type 2 diabetes, it’s important to remember that it’s just one part of a comprehensive treatment plan.
Maintaining a healthy diet, regular exercise, and other lifestyle changes are crucial for managing diabetes effectively.
Ozempic and Pregnancy: The Risks
Animal studies on Ozempic during pregnancy
Research on animals has provided insights into the potential effects of Ozempic during pregnancy. These studies have shown some concerning results:
In rats, the use of semaglutide (the active ingredient in Ozempic) during pregnancy was linked to lower birth weights and structural abnormalities in offspring.
Similar effects were observed in rabbits, with early pregnancy losses and structural abnormalities occurring at doses below the maximum recommended human dose (MRHD).
Studies on cynomolgus monkeys revealed early pregnancy losses and structural abnormalities at exposures 10 times higher than the MRHD.
It’s important to note that in rabbits and monkeys, these findings coincided with significant maternal weight loss.
However, it’s crucial to remember that these studies used doses much higher than those typically prescribed to humans. Also, results from animal studies don’t always translate directly to human outcomes.
Potential risks to the fetus
Based on the animal studies, there are concerns about potential risks to the fetus if Ozempic is used during pregnancy. These risks may include:
- Increased risk of miscarriage
- Lower birth weight
- Structural abnormalities in various organs and tissues
- Potential effects on fetal development
It’s important to note that the exact risks in humans are not yet fully understood. The limited data available makes it challenging to determine a direct cause-and-effect relationship between Ozempic and these potential risks in human pregnancies.
One theory suggests that these risks might be related to maternal weight loss rather than a direct effect of the medication. Significant weight loss during pregnancy is generally not recommended as it can lead to complications.
Another concern is the potential impact of Ozempic on nutrient absorption. The medication can interfere with digestion, which might make it harder for your body to absorb essential nutrients needed for fetal development.
FDA recommendations
Given the potential risks and limited data on human pregnancies, the U.S. Food and Drug Administration (FDA) has issued specific recommendations regarding Ozempic and pregnancy:
- Discontinuation before pregnancy: The FDA recommends stopping Ozempic at least two months before planning to become pregnant. This recommendation is based on the fact that semaglutide can remain in your system for some time after discontinuation.
- Immediate discontinuation if pregnancy occurs: If you become pregnant while taking Ozempic, you should stop the medication immediately and inform your healthcare provider.
- Breastfeeding considerations: The FDA also advises against taking Ozempic while breastfeeding, as the drug can enter breast milk.
- Pregnancy Category C: The FDA has classified Ozempic under Pregnancy Category C. This means that animal studies have shown adverse effects on the fetus, but there aren’t adequate studies in humans to confirm these risks. Medications in this category should only be used during pregnancy when the potential benefits justify the potential risks to the fetus.
- Need for further research: The FDA has requested additional studies to investigate health outcomes in people exposed to Ozempic during pregnancy. This includes analyzing complications in pregnancies that have already occurred and establishing a registry to follow health outcomes in a group of people exposed to Ozempic during pregnancy.
It’s crucial to have an open discussion with your healthcare provider about managing your diabetes during pregnancy.
They can help weigh the potential risks and benefits of using Ozempic or suggest alternative treatments that are considered safer during pregnancy, such as insulin therapy or metformin.
Remember, maintaining stable blood glucose levels during pregnancy is vital for both your health and your baby’s development.
Your healthcare provider can work with you to create a personalized plan that ensures the best possible outcomes for you and your baby.
Managing Diabetes During Pregnancy
Managing diabetes during pregnancy is crucial for the health of both you and your baby. It’s essential to work closely with your healthcare team to develop a comprehensive plan that addresses your specific needs.

This plan may include alternative medications and strategies to maintain optimal blood sugar control throughout your pregnancy.
Alternative medications for pregnant women with diabetes
If you’re pregnant and have diabetes, your healthcare provider may recommend changes to your medication regimen.
Insulin is often considered the gold standard for treating high blood sugar during pregnancy when lifestyle measures alone are not sufficient.
Unlike some oral medications, insulin doesn’t cross the placenta, making it safe for your baby.
However, recent studies have suggested that certain oral hypoglycemic agents may be safe alternatives for some women. Metformin, for instance, has shown promise in managing gestational diabetes.
Despite crossing the placenta, there are no serious safety concerns associated with its use. In fact, metformin has been linked to reduced neonatal hypoglycemia, decreased maternal hypoglycemia, and less weight gain compared to insulin treatment.
Another medication that has gained attention is glyburide (also known as glibenclamide). Some studies have found it to be more effective than metformin in lowering blood glucose levels in women with gestational diabetes, with a lower treatment failure rate.
It’s important to note that the use of oral anti-diabetic drugs during pregnancy is not universally recommended.
The American Dental Association (ADA) does not endorse their use, while the UK National Institute for Health and Care Excellence (NICE) considers metformin and glyburide safe during pregnancy and lactation.
Currently, no oral anti-diabetic agents are approved by the U.S. Food and Drug Administration (FDA) for treating diabetes in pregnancy.
The Endocrine Society has provided guidelines regarding the use of oral anti-diabetic agents during pregnancy. They suggest that glyburide may be a suitable alternative to insulin therapy for women with gestational diabetes who don’t achieve sufficient glycemic control after a one-week trial of meal planning and exercise.
However, insulin therapy is preferred for women diagnosed with gestational diabetes before 25 weeks of gestation or those with fasting plasma glucose levels above 110 mg/dL (6.1 mmol/L).
As for metformin, it may be considered for women with gestational diabetes who don’t have satisfactory glycemic control despite dietary changes and exercise, and who refuse or cannot use insulin or glyburide. However, it’s not recommended during the first trimester.
Importance of blood sugar control during pregnancy
Maintaining proper blood sugar control during pregnancy is vital for your health and your baby’s development. High blood glucose levels, especially during the first weeks of pregnancy, can harm your baby even before you know you’re pregnant.
This underscores the importance of planning ahead and working to get your blood glucose levels close to your target range before conception.
Throughout your pregnancy, hormonal changes will affect your blood glucose levels, potentially requiring adjustments to your diabetes management plan.
You may need to modify your meal plan, physical activity routine, and medications. If you’ve been taking oral diabetes medications, your healthcare provider might recommend switching to insulin.
Keeping your blood glucose as close to normal as possible before and during pregnancy can help prevent complications for both you and your baby.
Some potential risks associated with poorly controlled blood sugar include:
- Excessive birth weight (macrosomia)
- Increased likelihood of needing a cesarean section
- Higher risk of preterm delivery
- Respiratory distress syndrome in the baby
- Low blood sugar (hypoglycemia) in the baby shortly after birth
- Increased risk of birth defects
To help manage your blood sugar effectively, your healthcare team may recommend frequent blood glucose monitoring.
The American Diabetes Association suggests the following target ranges for women with gestational diabetes:
- Before meals: 95 mg/dL or less
- One hour after a meal: 140 mg/dL or less
- Two hours after a meal: 120 mg/dL or less
Remember, these targets may vary based on your individual circumstances, so it’s essential to work closely with your healthcare provider to determine the best goals for you.
Ozempic During Pregnancy
The use of Ozempic during pregnancy has a significant impact on both maternal and fetal health. While it’s effective for managing blood sugar in adults with type 2 diabetes, its potential risks to fetal development can’t be overlooked.

The FDA’s recommendations to stop Ozempic before planning a pregnancy and to discontinue it immediately if pregnancy occurs highlight need for caution.
This means expectant mothers and their healthcare providers must carefully weigh the benefits against the possible risks.
For women with diabetes who are pregnant or planning to conceive, there are alternatives to consider. Insulin remains a trusted option, while some oral medications like metformin show promise under certain conditions.
The key is to work closely with your healthcare team to develop a personalized plan. This approach ensures the best possible outcomes for both mother and baby, keeping in mind that maintaining stable blood sugar levels during pregnancy is crucial for healthy fetal development.
