Mounjaro is a new medication used to manage blood sugar levels in people who have type 2 diabetes. This medication offers weight loss and cardiovascular benefits, which can also help with insulin resistance.

Mounjaro is a relatively new diabetes medication used to help improve blood sugar and A1C levels in people with type 2 diabetes.

However, many people are not familiar with exactly what the medication is, what it does, and if it can really help with insulin resistance.

This article explores everything you need to know about Mounjaro as it relates to insulin resistance.

Mounjaro is the name brand for the Eli Lilly-manufactured drug tirzepatide. The Food and Drug Administration (FDA) approved it in 2022 for managing blood sugar levels in people with type 2 diabetes.

It’s the first medication available in the United States that activates both the glucagon-like peptide 1 (GLP-1) agonist and glucose-dependent insulinotropic peptide (GIP) receptors, making it more effective for managing blood sugar, A1C, and weight than other diabetes medications.

Specifically, Mounjaro can help with insulin resistance in a few ways.

This medication improves blood sugar levels and helps with insulin resistance by increasing the amount of insulin the pancreas releases, but only when your blood sugar is rising. That means there is no risk of low blood sugar levels while taking the medication.

It also stops your liver from releasing sugar into the blood, resulting in lower blood sugar levels.

While not FDA approved as a weight loss drug, it also aids in weight loss and maintenance by helping reduce food intake by lowering appetite and slowing digestion.

Mounjaro may sometimes be prescribed off-label (doctor-prescribed use other than what it is FDA-approved to treat) to help people with insulin resistance lose weight, even if they do not have diabetes.

Whether or not you have diabetes, when you lose weight, your insulin resistance improves.

Experiencing better blood sugar levels without lows and losing weight can lead to improved insulin sensitivity.

While there is no best drug for improving insulin resistance, many drugs can treat the root causes of insulin resistance. These may include obesity, type 2 diabetes, and a sedentary lifestyle.

The most commonly prescribed medication to treat insulin resistance is metformin.

You can discuss treatment options with your healthcare team. They can help you determine whether a different GLP-1 agonist medication like Ozempic, Victoza, or Trulicity might be best for you or whether a combination GLP-1 and GIP medication like Mounjaro might work best.

Mounjaro may help people without diabetes lower their insulin resistance and lose weight.

However, since it is not FDA approved as a stand-alone weight loss medication, you may experience challenges in trying to get a healthcare professional to prescribe it for that off-label use. Many health insurance plans may also not cover the cost of the drug.

Whether or not you have diabetes, medications like Mounjaro can improve insulin resistance, aid in the lowering of blood sugar and A1C levels, and may help with weight loss.

In clinical trials, people taking 15 milligrams of Mounjaro per week lost:

  • 12 pounds (lb) more than participants on the GLP-1 medication (semaglutide)
  • 29 lb more than participants on insulin degludec
  • 27 lb more than participants on insulin glargine

Mounjaro stimulates insulin release in response to high blood sugar levels, helping improve insulin resistance.

When hormones like insulin and glucagon are released in the body, it reduces hunger, decreases appetite and food intake, and makes you feel fuller for longer, all resulting in weight loss.

More research needs to be done to test the efficacy of Mounjaro as a preventive measure against prediabetes and type 2 diabetes.

However, given its strong effectiveness on weight loss and insulin sensitivity, it may be helpful in preventing the weight gain and insulin resistance that often accompany a prediabetes or type 2 diabetes diagnosis.

Additionally, along with diet and physical activity, such as exercise, Mounjaro may help with reversing prediabetes and may even help people in weaning or getting off their type 2 diabetes medications, but this largely remains to be seen.

Mounjaro is a new drug approved for people 18 years and older with type 2 diabetes. It can help improve insulin resistance, as well as aid in weight loss and improve blood sugar and A1C levels.

It is currently only FDA approved for treatment in people living with type 2 diabetes. However, more and more people are taking it off-label. It’s important to note that you should never take Mounjaro if your healthcare team has not approved it and provided a prescription.

You can consult your doctor and healthcare team about any questions related to Mounjaro and whether it may help improve your health.
