What Do I Need to Know About Mounjaro and Pregnancy?

Pregnancy brings about numerous changes in a woman’s body, and for many expectant mothers, maintaining good health is of utmost importance. With this in mind, it’s essential to make informed decisions about medications, including those used to manage conditions like diabetes or obesity. One of the latest medications to gain attention in these areas is Mounjaro (tirzepatide), a drug primarily used for type 2 diabetes management and weight loss. However, if you’re pregnant or planning to become pregnant, it’s important to understand how Mounjaro fits into your antenatal care plan, especially since it is not legal in the UK at this time.

In this article, we’ll dive into the details of Mounjaro, its similarities to Ozempic (semaglutide), and why both medications are generally not prescribed during pregnancy. We’ll also discuss the importance of antenatal support and offer guidance on what pregnant women need to know when it comes to medication use during pregnancy.

Mounjaro (tirzepatide) is a relatively new medication that was approved in the United States by the U.S. Food and Drug Administration (FDA) in 2022 for the treatment of type 2 diabetes. It works by mimicking two hormones—GLP-1 and GIP—which help control blood sugar levels and appetite. In addition to regulating blood sugar, it has been shown to promote significant weight loss, making it a popular option for people managing obesity.

However, as of now, Mounjaro is not legal in the UK. It has not been approved by the UK Medicines and Healthcare products Regulatory Agency (MHRA) or the European Medicines Agency (EMA) for use in the UK. Although it has shown promise, particularly in terms of weight loss and diabetes management, it has yet to be cleared for use in the UK market. Therefore, if you’re living in the UK and are pregnant or planning a pregnancy, this medication would not be available to you as part of your antenatal care plan.

Mounjaro vs Ozempic: Similarities and Pregnancy Considerations

Mounjaro shares some important similarities with another well-known medication, Ozempic (semaglutide). Both medications belong to a class of drugs called GLP-1 receptor agonists, which mimic the natural GLP-1 hormone to help regulate blood sugar and appetite. Ozempic has been available for some time and is commonly used to treat type 2 diabetes. Like Mounjaro, it has also been shown to have a positive effect on weight loss, which has led to its off-label use for obesity management.

Why Ozempic and Mounjaro Aren’t Recommended During Pregnancy

While Mounjaro is not yet available in the UK, it’s worth noting that Ozempic, another GLP-1 receptor agonist, has similar risks and considerations during pregnancy. Both drugs work in a similar manner and carry potential risks for pregnant women. As a result, neither Mounjaro nor Ozempic is recommended for use during pregnancy.

Risk to the Baby

There is limited research on the safety of GLP-1 receptor agonists like Ozempic and Mounjaro during pregnancy, but existing animal studies suggest that these medications could pose risks to fetal development. Specifically, these drugs have been linked to malformations in animal models, particularly affecting the skeletal and cardiovascular systems. Although these findings are based on animal studies, they are taken seriously by healthcare professionals, especially in the absence of reliable human data.

Potential for Pregnancy Complications

Both Ozempic and Mounjaro can also influence insulin secretion and blood sugar regulation, which may affect the developing fetus. Pregnancy already alters a woman’s insulin sensitivity, and adding a medication that alters blood sugar levels could lead to complications like hypoglycemia (low blood sugar), which can be harmful to both the mother and baby.

Moreover, GLP-1 receptor agonists can cause gastrointestinal side effects such as nausea and vomiting. These side effects could be particularly problematic during pregnancy when digestive issues such as morning sickness are common.

Ozempic and Pregnancy: Impact on Fertility and Unplanned Pregnancy

While Ozempic is unlikely to be prescribed during pregnancy due to the aforementioned risks, it’s important to note that Ozempic and Mounjaro may affect fertility and the chances of an unplanned pregnancy.

Some studies suggest that weight loss medications like Ozempic may have an impact on a woman’s menstrual cycle and fertility. While not directly causing infertility, these drugs can alter hormone levels, which may make conception more difficult for some women. On the flip side, if you were already using Ozempic and unexpectedly became pregnant, it would be crucial to stop the medication immediately and consult with your healthcare provider to ensure the best possible care for both you and your baby.

Alternatives to Mounjaro and Ozempic During Pregnancy

Given the risks associated with Mounjaro and Ozempic, particularly during pregnancy, it’s crucial to explore alternative treatments. If you are pregnant and need help managing type 2 diabetes or weight gain, your healthcare provider will be able to offer other options that are safer during pregnancy.

Insulin Therapy: Insulin is considered the gold standard for managing diabetes during pregnancy. Unlike GLP-1 receptor agonists, insulin does not cross the placenta, meaning it doesn’t pose a direct risk to the fetus.

Metformin: Metformin is another commonly prescribed medication for managing type 2 diabetes and gestational diabetes. It has been well studied and is considered safe during pregnancy. However, it should only be used under the guidance of your healthcare provider.

Lifestyle Modifications: For managing weight gain and diabetes during pregnancy, lifestyle changes are always an important first step. This may include following a healthy, balanced diet and engaging in regular antenatal fitness activities like prenatal yoga. Yoga during pregnancy can improve flexibility, reduce stress, and even help with blood sugar control, making it an excellent choice for women managing diabetes and weight gain.

The Importance of Antenatal Care and Support

If you are pregnant, it’s crucial to attend regular antenatal appointments and work closely with your healthcare provider to ensure both your health and the health of your baby. During these appointments, you can discuss any medications you are taking, including those for type 2 diabetes or weight management. Your doctor will help you navigate safe treatment options and provide antenatal support tailored to your needs.

Additionally, antenatal care goes beyond medication; it also involves monitoring your physical and emotional wellbeing. Consider joining antenatal classes or finding a support network that can offer information and resources as you move through your pregnancy.

What Should You Do About Mounjaro and Ozempic During Pregnancy?

In conclusion, Mounjaro is not legal in the UK and has not been approved for use here, while Ozempic, though available, is generally not prescribed during pregnancy due to potential risks to the developing fetus. If you are pregnant, it’s essential to work closely with your healthcare provider to explore safer alternatives for managing type 2 diabetes, weight gain, or other conditions. Insulin therapy, metformin, and lifestyle modifications are safer options, and incorporating activities like antenatal yoga and fitness into your routine can further promote your health and well-being during pregnancy.

Remember, always consult your doctor before starting or stopping any medication during pregnancy to ensure the best possible outcome for you and your baby.
