We take a close look at two drugs with a lot in common that people with Type 2 diabetes may have heard of. They have the same active ingredient, Semaglutide, help with weight loss, and are even made by the same company. So when we look at Wegovy vs Ozempic – they must be the same, right? No! What sets them apart is they’re prescribed to serve different needs: blood sugar control or chronic weight management.
Below we do a deep dive on Ozempic and Wegovy, how they work, and the key differences and similarities.
Wegovy and Ozempic: How They’re Similar
The main thing Ozempic and Wegovy have in common is the active ingredient, Semaglutide.
Semaglutide is an analog to the glucagon-like peptide-1 (GLP-1) hormone. In other words, Semaglutide acts like the GLP-1 hormone by activating the GLP-1 receptors.
The GLP-1 hormone, produced in the intestines, plays many roles when it comes to blood glucose. This includes telling the pancreas to produce more insulin (a hormone that absorbs blood glucose) and slowing the release of glucagon (a hormone that increase glucose).
The GLP-1 hormone also inhibits (or slows) stomach emptying, which results in glucose breaking down slower. And it also helps make you feel more satisfied in order to help slow food intake.
Helps with Weight Loss
Both Wegovy and Ozempic can help lead weight loss. Below we discuss studies on both medications showing participants saw average weight loss between 9lbs to 35lbs.
Wegovy and Ozmepic are both made by the company Novo Nordisk, a Danish pharmaceutical company.
There also both relatively new. Wegovy was FDA approved in June 2021 and Ozempic first FDA approved in 2017. But Ozempic’s higher dose was approved in March 2022.
Side Effects and Warnings
Because they use the same active ingredient, Semaglutide, they have similar side effects and warnings.
We discuss these more below but the more serious side effects may include possible thyroid tumors (including cancer), pancreatitis, gallbladder problems, hypoglycemia, and kidney problems.
Wegovy and Ozempic: How They’re Different
Now that we know what Wegovy and Ozempic have in common, below we look at how they’re different.
The main difference is the two medications serve different needs.
Ozempic is a drug for adults with type 2 diabetes and is intended to improve their blood sugar. And while it’s not a weight loss drug, it may also help you lose some weight.
But Wegovy is a weight management medicine. It’s meant for adults that are overweight or obese – at or above body mass index (BMI) of 27 – with weight-related medical issues in order to help with sustained weight loss.
Another difference is the dosing schedule of the two with Wegovy having slightly higher doses.
Wegovy is prescribed in five (5) dose strengths of 0.25mg, 0.5mg, 1mg, 1.7mg, 2.4mg that’s over five months.
The starting dose of 0.25mg is given for one month, and then increased to the next dose strength per month until the maximum dose of 2.4mg is reached.
Ozempic only has only four (4) dose strengths of 0.25mg, 0.5mg, 1mg and 2mg.
Ozempic recommends that dosage increases only up to 0.5mg at 4 weeks and stays there if A1C is under control. But if not, the doctor may increase dosage to 1mg or 2mg to improve glycemic control.
As we discuss below, the list price of Wegovy is a lot higher than Ozempic. But certain medical insurance coverage will bring those costs down.

In the company’s 68-week study, adults lost an avg. 35lbs or 15% body weight. And over 60% lost at least 10% body weight. This study didn’t include people with type 2 diabetes so impacts to blood sugar or A1C wasn’t included.

The study also showed participants lost an average of 9.3lbs on the 0.5mg dose, and an average of 12.8lb on 1mg dose. This was more weight lost on Ozempic than other similar medications.
