If you are overweight or obese, you may have heard of Wegovy and Ozempic. They are popular for treating type 2 diabetes. Both medications are GLP-1s (glucagon-like peptide-1 receptor agonists). The active component in each of them is Semaglutide.
The medications Wegovy and Ozempic are identical; they are just marketed differently. Each pen has a different amount of Semaglutide. Semaglutide was first approved in 2017 as Ozempic. It treats type 2 diabetes.
In 2021, the FDA approved Wegovy as a weight loss drug. Doctors frequently recommend both b Regulators have approved Ozempic for treating type 2 diabetes. Some doctors may prescribe Ozempic off-label for weight loss.
There are variations in some of the doses offered for each drug. Every Wegovy injection pen also comes with an integrated needle. Ozempic pens come with separate needles to attach before each dose. In this post we will talk about the Ozempic and Wegovy for weight loss, their key differences and which one is right for you.
Ozempic and Wegovy for Weight Loss: Key Differences
Wegovy and Ozempic are brand-name injectables. They are both prescription drugs. They contain the same active ingredient: Semaglutide. Both are glucagon-like peptide-1 receptor agonists (GLP-1s). Ozempic and Wegovy for weight loss are similar, but the FDA has approved them for different uses.
The FDA has approved Ozempic for:
- Managing blood sugar in people with type 2 diabetes who are older than 18 years old.
- Reducing the risk of serious heart problems in adults with type 2 diabetes and heart disease. These issues include deaths, strokes, and heart attacks.
In contrast, the FDA has approved Wegovy for weight management in adults 18 and older with either:
- Obesity: body mass index (BMI) of 30 kg/m2 or greater.
- Overweight: a BMI of 27 kg/m2 or more and one weight-related condition, like type 2 diabetes or high blood pressure.
In 2024, the FDA approved Wegovy for a new use. It can reduce heart disease risk in adults who are obese or overweight. They must also have heart disease.
How you use Ozempic and Wegovy pens is another important distinction between the two medications. With Wegovy, each injection pen has a built-in needle. After you use the pen once, you’ll dispose of it in a sharps container.
Ozempic comes with needles that you’ll attach to the injector pen before each dose. Then, you’ll dispose of the needle in a sharps container, but continue using the same pen several times.
These are the key differences between Ozempic and Wegovy in terms of weight loss.
How Does Ozempic Work?
As a GLP-1, Ozempic acts like the natural hormone GLP-1. It binds to GLP-1 receptors. It tells the pancreas to release insulin when blood sugar spikes. Increased insulin in the body brings blood sugar levels back down. Ozempic mimics the GLP-1 hormone. It is very effective at stabilizing blood glucose in people with type 2 diabetes.
Ozempic also stabilizes blood sugar by slowing digestion. It keeps food in the stomach longer. It limits sugar release into the bloodstream. It also lowers food intake by reducing appetite. Lastly, after eating, GLP-1 receptor agonists like Ozempic alert the brain to your fullness. This adds another layer of appetite regulation. Due to its effects on appetite, Ozempic is often prescribed off-label for weight loss.
How Does Wegovy Work?
Wegovy works the same as Ozempic. Wegovy raises the body’s GLP-1 levels. It keeps food in the stomach longer and signals the brain that you’re full. All that helps regulate your appetite and leads to significant weight loss.
A trial found that participants who took the highest dose of Wegovy, and made lifestyle changes lost 15% of their body weight by the end of the 68-week trial.
Ozempic vs Wegovy: Which Is More Effective?
Wegovy often requires a larger maintenance dosage than Ozempic. It comes in higher doses of semaglutide. Ozempic comes in 0.25 mg, 0.5 mg, 1.0 mg, and 2 mg strengths. Wegovy comes in 0.25 mg, 0.5 mg, 1.0 mg, 1.7 mg, and 2.4 mg single-use pens.
This means you can take Wegovy at a higher dose than Ozempic, but you do have to ramp up over five months. If appropriate, your provider can raise your Ozempic dose to 2 mg once a week for blood sugar control. This is the highest dose.
A trial compared weekly use of semaglutide 1 mg and 2.4 mg. Wegovy, semaglutide 2.4 mg, caused more weight loss than the typical maintenance dose of Ozempic, semaglutide 1 mg.
A trial found that a common Wegovy dose of 2.4 mg of semaglutide, plus diet and exercise, led to a 15% weight loss by 68 weeks. In comparison, people with diabetes taking 1 mg of semaglutide (a common Ozempic dose) lost 7% of their body weight, on average, over 68 weeks. They also followed a diet and exercised.
Both Wegovy and Ozempic for weight loss can be effective treatment options. If you’re unsure if any of these drugs are suitable for you, a healthcare professional may provide you with advice.
