When considering treatment options, it’s essential to compare and contrast different medications. In this context, Wegovy and Mounjaro are two notable options. Let’s explore and analyze their mechanisms, side effects, and effectiveness
An Overview of Wegovy
Wegovy, known generically as semaglutide, is a prominent medication in managing obesity and type 2 diabetes. It belongs to a class of drugs known as GLP-1 receptor agonists. It is a prescription drug primarily used for weight management in adults with obesity or overweight who have weight-related medical problems. It works by mimicking a hormone that targets areas of the brain involved in appetite regulation, thereby reducing hunger and calorie intake.
Approved by Health Canada in 2022, Wegovy is administered through once-weekly subcutaneous injections. It’s distinct from other weight-loss medications due to its higher dose of semaglutide.
How Does Wegovy Work?
Wegovy functions by mimicking the effects of a hormone called glucagon-like peptide-1 (GLP-1), which is naturally produced in the body. GLP-1 plays a crucial role in appetite regulation and calorie & food intake.
When introduced into the body, Wegovy binds to GLP-1 receptors in the brain, particularly in areas responsible for regulating appetite and food intake. This binding action enhances the body’s natural response to GLP-1, leading to appetite suppression and increased feelings of fullness. As a result, individuals on Wegovy tend to consume fewer calories, aiding in gradual and sustained weight loss.
Additionally, Wegovy has been observed to slow gastric emptying, further contributing to a decrease in appetite and caloric intake. It’s important to note that while Wegovy is effective in promoting weight loss, it works best when combined with a healthy diet and regular exercise.
An Overview of Mounjaro
Mounjaro, generically known as tirzepatide, is a relatively new medication approved by Health Canada in 2022. It represents a novel class of diabetes medication, as it is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist.
This dual action enables Mounjaro to effectively lower blood sugar levels by enhancing insulin secretion, reducing the liver’s glucose production, and slowing gastric emptying.
It is administered through a subcutaneous injection, typically once a week.
How Does Mounjaro Work?
Mounjaro functions through its innovative dual-action mechanism as a combined agonist of both the glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors. This dual receptor activity is a first in diabetes treatment.
By stimulating the GLP-1 receptor, Mounjaro enhances insulin secretion in response to high blood sugar levels, while simultaneously reducing glucagon secretion, a hormone that raises blood sugar levels.
The GIP receptor activity complements this by further improving insulin release and decreasing glucagon secretion.
Additionally, Mounjaro slows gastric emptying, contributing to a decrease in appetite and caloric intake, which assists in weight management—a crucial aspect for many individuals with type 2 diabetes.
This combined approach not only helps in effectively lowering blood sugar levels but also supports weight loss, making it a significant advancement in diabetes care.
Wegovy vs. Mounjaro: What are the Differences?
The main difference between Wegovy and Mounjaro lies in their mechanisms of action, dosage, approval for certain uses, and effectiveness.
Wegovy and Mounjaro, while both used in the management of related health issues, differ significantly in their composition and primary indications.
Approved Use
- Wegovy: Approved for weight management in adults with obesity or overweight with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol.
- Mounjaro: Primarily approved for the treatment of type 2 diabetes; research on its use for obesity is ongoing.
Effectiveness in Weight Loss
Recent studies have found that patients on tirzepatide (the active ingredient in Mounjaro) were significantly more likely to achieve 5%, 10%, and 15% weight loss and experience larger reductions in weight at 3, 6, and 12 months than those on semaglutide (the active ingredient in Wegovy).
While both drugs can lead to significant weight loss and improved blood sugar levels in people with type 2 diabetes, it’s also important to remember that the extent of effectiveness can vary based on individual factors such as body mass index (BMI), existing health conditions and adherence to the treatment plan.
The remarkable weight loss results associated with Mounjaro may intrigue many readers seeking more information. To delve deeper into this topic, our in-depth exploration of weight loss with Mounjaro offers additional insights and success stories.
Approval for Weight Loss
While Wegovy is approved specifically for weight loss, Mounjaro’s current approval is for type 2 diabetes management. This distinction is crucial for insurance coverage and prescription considerations.

Wegovy vs. Mounjaro Side Effects
Comparing the side effects of Wegovy and Mounjaro reveals some similarities and differences, reflecting their distinct mechanisms of action. Both medications, operating as GLP-1 receptor agonists, commonly cause gastrointestinal-related side effects, though the extent and nature of these effects can vary.
Wegovy (Semaglutide) Side Effects
– Nausea
– Diarrhea
– Vomiting
– Constipation
– Abdominal pain
– Headache
– Fatigue
– Increased risk of thyroid C-cell tumors (in animal studies)
Mounjaro (Tirzepatide) Side Effects
– Nausea
– Diarrhea
– Reduced appetite
– Vomiting
– Abdominal pain
– Constipation
– Headache
– Hypoglycemia (especially when used with other diabetes medications)
While both medications share common side effects like nausea and diarrhea, Wegovy has a noted concern for thyroid C-cell tumors observed in animal studies. On the other hand, Mounjaro, due to its dual action on GIP and GLP-1 receptors, may have an increased risk of hypoglycemia, particularly when combined with other diabetes medications. It’s crucial for individuals to consult with healthcare professionals to understand these side effects in the context of their personal health conditions and treatment plans.
