Mounjaro® (tirzepatide) is a once-weekly injectable medication approved to help adults with type 2 diabetes improve their blood sugar levels. It works by targeting two hormone receptors involved in metabolic regulation.

Additionally, Mounjaro has been shown in clinical studies to support significant metabolic improvements, including better insulin sensitivity and appetite regulation. Although it is not FDA-approved for weight loss, many individuals may experience weight changes as a secondary effect.

Mounjaro should be used alongside a reduced-calorie diet and increased physical activity as part of a long-term treatment plan.

Mounjaro works by activating two metabolic hormone pathways: GLP-1 and GIP. This dual mechanism is unique to tirzepatide and is designed to provide more comprehensive metabolic support.

The medication helps:

• Improve insulin release in response to elevated blood sugar

• Reduce glucagon levels (a hormone that raises blood sugar)

• Slow gastric emptying to support fullness and appetite regulation

• Influence brain receptors involved in hunger and satiety

Together, these effects help regulate blood sugar, reduce appetite, and improve metabolic function.

Mounjaro is not approved for weight loss, but weight changes have been observed in clinical studies. These effects are believed to come from the medication’s impact on appetite, digestive speed, and insulin response.

Some individuals may experience meaningful weight reduction, while others may see smaller or no changes. Results depend on dose, diet, physical activity, consistency, and personal metabolic differences.

Good Girl Rx emphasizes that weight change should not be considered a guaranteed outcome with Mounjaro.

Many people notice improvements in blood sugar control within the first few weeks. As the dose increases, individuals may experience additional benefits such as reduced appetite or improved metabolic balance.

However, full therapeutic effects often take several weeks to months, depending on dose escalation and individual response. Consistency—taking the medication weekly—is essential for achieving results.

Mounjaro is intended for adults with type 2 diabetes who need improved blood sugar control. Individuals with a history of type 1 diabetes or diabetic ketoacidosis should not use Mounjaro.

Mounjaro is also not recommended for individuals with:

• A personal/family history of medullary thyroid carcinoma (MTC)

• Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)

• A history of pancreatitis

• Serious gastrointestinal diseases

A Good Girl Rx provider will evaluate your medical history and determine whether this treatment is appropriate.

The most common side effects involve the digestive system, especially during the first few weeks. These may include:

• Nausea

• Vomiting

• Diarrhea or loose stools

• Constipation

• Decreased appetite

These symptoms typically improve as your body adjusts. If side effects become severe or persistent, your provider may adjust your dose or offer guidance to help manage them.

Both medications contain tirzepatide, but they are approved for different uses.

Mounjaro®: FDA-approved for type 2 diabetes.

Zepbound®: FDA-approved for chronic weight management.

Although they share the same active ingredient, they differ in approved indications, dosing, labeling, and clinical guidelines. They are not interchangeable.

No. Mounjaro should not be used with:

• GLP-1 receptor agonists

• Other tirzepatide medications

• Weight-loss injections or appetite suppressants

Combining medications that act on similar pathways can increase risks and is not recommended. Your Good Girl Rx provider will review all your medications to ensure safe use.

Insurance coverage depends heavily on the plan. Many commercial insurance providers cover Mounjaro for type 2 diabetes, but not for weight-related purposes alone. This can vary greatly between insurance companies.

Good Girl Rx offers:

• Insurance support: Full benefit verification and coordination with your plan.

• Cash-pay options: Transparent pricing if insurance coverage is limited or unavailable.

Your provider and our support team can guide you through both pathways.
