Diabetes Management in Pregnancy: Why Jardiance Is Monitored Closely

Managing diabetes during pregnancy is essential for the health of both mother and baby. Blood sugar levels that are too high can increase the risk of complications, including preeclampsia, premature birth, and excessive birth weight. Because of these risks, medication choices during pregnancy are carefully evaluated.

One medication that often raises questions is Jardiance (empagliflozin). While it is widely used to treat type 2 diabetes in non-pregnant adults, it is closely monitored and generally not recommended during pregnancy. Understanding why can help you make informed decisions with your healthcare provider.

What Is Jardiance?

Jardiance belongs to a class of medications called SGLT2 inhibitors (sodium-glucose co-transporter 2 inhibitors). It works by:

• Helping the kidneys remove excess glucose through urine
• Lowering blood sugar levels
• Supporting heart health in certain patients
• Reducing the risk of cardiovascular complications in people with type 2 diabetes

In non-pregnant adults, Jardiance can be highly effective. However, pregnancy changes how medications affect the body — and the developing baby.

Why Is Jardiance Monitored Closely During Pregnancy?

1. Limited Safety Data in Pregnant Women

There are no well-controlled clinical trials of Jardiance in pregnant women. Because of this, healthcare providers rely on animal studies and post-marketing data.

In animal studies, SGLT2 inhibitors have shown potential risks to developing kidneys when exposure occurred during certain stages of pregnancy. Since a baby's kidneys continue developing in the second and third trimesters, medications that affect kidney function are approached cautiously.

When safety data is limited, doctors typically recommend medications with a longer, proven safety history in pregnancy — such as insulin.

2. Potential Effects on Fetal Kidney Development

Jardiance works directly on the kidneys. During pregnancy:

• The fetus is developing kidney structures.
• Exposure to medications affecting kidney function could theoretically interfere with normal growth.

Although human data is limited, this theoretical risk is significant enough that most professional guidelines recommend avoiding SGLT2 inhibitors during pregnancy, especially in the second and third trimesters.

3. Risk of Dehydration and Low Blood Pressure

One of the known Jardiance side effects is increased urination. While this helps lower blood sugar, it can also:

• Increase risk of dehydration
• Lower blood pressure
• Cause dizziness or fainting

Pregnant women already experience changes in blood volume and circulation. Additional fluid loss may increase the risk of complications, especially if nausea or vomiting is present.

---

4. Risk of Diabetic Ketoacidosis (DKA)

Although uncommon, SGLT2 inhibitors like Jardiance have been associated with euglycemic diabetic ketoacidosis (DKA) — a serious condition where acid levels rise in the blood even when blood sugar is not extremely high.

Pregnancy itself increases the risk of DKA. Combining pregnancy with a medication that may elevate that risk makes doctors cautious.

Symptoms of DKA may include:

• Nausea or vomiting
• Abdominal pain
• Rapid breathing
• Confusion
• Fatigue

DKA is a medical emergency and requires immediate treatment.

Common Jardiance Side Effects

Understanding general Jardiance side effects helps explain why the medication requires close monitoring, even outside of pregnancy.

Common side effects include:

• Urinary tract infections (UTIs)
• Genital yeast infections
• Increased urination
• Dehydration
• Low blood pressure
• Increased thirst

More serious but less common side effects include:

• Diabetic ketoacidosis
• Acute kidney injury
• Severe urinary tract infections
• Allergic reactions

Pregnancy can increase susceptibility to infections and dehydration, which is another reason providers typically choose alternatives.

What Medications Are Preferred During Pregnancy?

For women with:

Pre-existing Type 1 or Type 2 Diabetes

Insulin is the gold standard treatment during pregnancy because:

• It does not cross the placenta in significant amounts
• It has a long history of safe use
• It can be precisely adjusted

Gestational Diabetes

Depending on severity, treatment may include:

• Lifestyle and dietary changes
• Blood sugar monitoring
• Insulin (if needed)
• In some cases, metformin (used selectively under medical guidance)

Your provider will individualize treatment based on:

• Blood sugar patterns
• Overall health
• Trimester of pregnancy
• Risk factors

---

Why Blood Sugar Control Matters So Much in Pregnancy

Uncontrolled diabetes during pregnancy can increase the risk of:

• High birth weight (macrosomia)
• Cesarean delivery
• Birth injuries
• Low blood sugar in the newborn
• Preeclampsia
• Preterm birth

The goal is steady, well-controlled glucose levels — not just lowering numbers quickly, but maintaining stability safely.

If You Are Taking Jardiance and Become Pregnant

If you are currently taking Jardiance and discover you are pregnant:

1. Do not panic.
2. Do not stop medication abruptly without medical advice.
3. Contact your healthcare provider promptly.

Your doctor will evaluate:

• How far along you are
• Your blood sugar control
• Alternative treatment options

Often, the medication will be discontinued and replaced with insulin or another safer option.

Monitoring and Shared Decision-Making

In rare situations, medication decisions may be complex. If a patient has significant cardiovascular disease or other serious conditions, specialists may weigh risks and benefits carefully.

Management may involve:

• An obstetrician
• An endocrinologist
• A maternal-fetal medicine specialist

Close monitoring may include:

• Frequent blood sugar checks
• Kidney function testing
• Blood pressure monitoring
• Fetal growth ultrasounds

The goal is always to protect both mother and baby.

Understanding Your Symptoms

If you are unsure whether you may have diabetes — or if you are experiencing symptoms such as:

• Increased thirst
• Frequent urination
• Blurred vision
• Fatigue
• Unexplained weight changes

You can use a free AI-powered Diabetes Mellitus symptom checker to help understand what your symptoms might mean and prepare for a more informed conversation with your healthcare provider.

However, an online tool should never replace professional medical care.

Balancing Benefits and Risks

Jardiance is an effective medication for many adults with type 2 diabetes. It has proven cardiovascular and kidney benefits in appropriate patients.

But pregnancy changes the equation.

Because of:

• Limited human safety data
• Potential fetal kidney risks
• Increased risk of dehydration
• Risk of ketoacidosis

Most medical guidelines recommend avoiding Jardiance during pregnancy, especially after the first trimester.

This cautious approach is not meant to alarm — it reflects a commitment to safety when evidence is limited.

---

When to Seek Immediate Medical Care

Seek urgent medical attention if you experience:

• Severe abdominal pain
• Persistent vomiting
• Rapid breathing
• Confusion
• Signs of severe dehydration
• High blood sugar that does not improve
• Decreased fetal movement (if later in pregnancy)

These symptoms could signal serious complications.

The Bottom Line

Jardiance is a valuable medication for many adults with type 2 diabetes, but it is closely monitored and generally avoided during pregnancy due to limited safety data and potential risks to fetal kidney development.

If you are pregnant or planning to become pregnant:

• Review all medications with your doctor
• Discuss safer alternatives
• Monitor blood sugar carefully
• Attend all prenatal appointments

Most importantly, speak to a doctor promptly about any symptoms that feel severe, unusual, or potentially life-threatening. Diabetes in pregnancy is manageable with the right care plan — and early, proactive treatment makes a significant difference.

With careful monitoring and medical guidance, most women with diabetes go on to have healthy pregnancies and healthy babies.
