Whether you’ve tried Ozempic and found it wasn’t for you or you’re just exploring your options before getting started, Zepbound and Wegovy are two popular weight management drugs you have at your disposal.
But what’s the difference between Wegovy and Zepbound? Is Zepbound better than Wegovy, or is it the other way around? We see these questions pop up all the time, so we’re going to cover everything you need to know about Zepbound vs Wegovy in this guide.
Zepbound uses tirzepatide, a compound that activates both GIP and GLP-1 hormone receptors. It not only helps manage hunger but can even improve insulin sensitivity and energy balance.
On the other hand, Wegovy contains semaglutide, a GLP-1 receptor agonist known for its strong appetite suppression and simplicity of use. That’s the main distinction in comparing Wegovy vs Zepbound - while they can accomplish the same goals, they do it very differently.

What is Zepbound?
Zepbound is a once-weekly injectable medication that uses the active ingredient tirzepatide. As we touched on above, this compound targets two key hormones that regulate hunger and blood sugar: GLP-1 and GIP.
Zepbound activates these receptors and helps slow digestion, reduce appetite, and improve the way your body handles insulin. The end result: less food intake and steadier energy throughout the day. That’s why you see people raving about their weight loss results from Zepbound.
While earlier drugs target just one pathway, tirzepatide engages two, which is how it potentially amplifies results for some users. A lot of people say they have much stronger control over their appetite and feel full from smaller portions than they normally would need to eat.
But like any weight loss drug, it’s important to look at both sides of the coin. Zepbound is known for causing an array of uncomfortable side effects, such as digestive discomfort. Nausea, constipation, bloating, and/or fatigue are all common as the body gets used to delayed gastric emptying.
Some people also notice dehydration or reduced food volume, leading to sluggish digestion. You could face high out-of-pocket costs if insurance doesn’t cover it, too. And because results fade when injections stop, you really need to commit to using Zepbound for the long haul.
That’s not to say Zepbound isn’t worth looking into further - just that there are a lot of moving pieces to consider. Let’s look at the other half of our Zepbound vs Wegovy comparison in the meantime.
What is Wegovy?
Wegovy works a bit differently, though we see a lot of people comparing Wegovy vs Zepbound. This drug relies on a different compound, one that’s more common in today’s weight loss drugs: Semaglutide. It’s the same GLP-1 receptor agonist that has made Ozempic so popular.
Semaglutide tells your brain you’re full sooner, so it’s easy to see the confusion between Zepbound vs Wegovy. They share this mechanism. Wegovy can also slow down how quickly your stomach empties and helps stabilize blood sugar levels between meals.
All of this translates to fewer cravings, less snacking, and gradual, sustained weight loss - with the “convenience” of a single weekly injection. Wegovy works, there’s little doubt about that. Clinical data show average weight reductions of around 15% when paired with lifestyle changes.
But while most people think about it for weight loss, Wegovy has also been studied for heart health benefits in people with obesity and cardiovascular risk factors. So what’s the catch?
Well, a lot of the same side effects you could face with Zepbound are a risk here, too. That includes nausea, constipation, diarrhea, and, for some, a feeling of fatigue or “slowing down.”
And as with most GLP-1 medications, the benefits tend to last only as long as you stay on the drug. Stopping abruptly can lead to a rebound in appetite and weight.
You can learn more about Wegovy vs Ozempic in our blog. For now, though, let’s zero in on the most important differences between Zepbound vs Wegovy.
Zepbound vs Wegovy: Key Differences to Consider
Both Zepbound and Wegovy sit in the same category of GLP-1–based medications, but they’re not interchangeable. The main similarity is in what they’re designed to do, but that’s where the differences between Zepbound and Wegovy start to show.
From the compounds they’re powered by to the degree of weight loss, potential costs/side effects, and more, here are all the most important nuances between Zepbound vs Wegovy.
Weight Loss Results
There’s no denying it. Both of these drugs can help you get your weight in check. Clinical trials for Wegovy show average weight reductions of roughly 15% after 68-72 weeks, while studies for Zepbound report an average of 15-21% (depending on dose).
In this sense, each drug can produce meaningful changes when combined with nutrition and activity adjustments. Some people say Zepbound is the better choice because of its dual-action design (GLP-1 + GIP) - but it really depends on tolerability at the end of the day.
Other Potential Benefits
Weight loss aside, there are other potential benefits associated with Zepbound and Wegovy. Both can potentially improve insulin sensitivity and help regulate blood sugar.
But Wegovy is unique in that it has an FDA indication for reducing major cardiovascular events in adults with obesity and heart disease. On the other hand, Zepbound is also approved for treating obstructive sleep apnea in people with obesity.
On top of all that, there’s reason to believe either drug could help support a better inflammatory response and improve metabolic markers - but lifestyle factors play a huge role in this, too.
Side Effects
From GLP-1 fatigue to GLP-1 nausea, there’s little you can do to escape the side effects of any weight management drug in this class. You should be prepared to deal with nausea, bloating, constipation, and slower digestion, especially at first, as the body adapts.
Your healthcare provider will discuss more rare but serious side effects of Zepbound/Wegovy, such as pancreatitis or gallbladder problems. In general, though, a lot of experts have said Wegovy’s single-pathway approach is sometimes gentler than Zepbound’s dual mechanism.
Dosing and Convenience
Zepbound and Wegovy may work through different compounds, but you’ll need an injection once a week either way. This is typically administered in the abdomen, thigh, or upper arm. So if you’re not comfortable with needles, you may have a hard time with these types of drugs.
Zepbound comes in several dosage tiers that are titrated up over time, and Wegovy works through a pretty similar step-up schedule. They’re virtually identical in terms of how they’re taken and the overall treatment plan.
That could be a good thing or a bad thing, depending on how you feel about constant injections.
Approval Process
Neither Zepbound nor Wegovy can be prescribed on demand. You have to get prescribed these types of drugs by a healthcare provider. And as we talk about in our guide on how to qualify for GLP-1, that’s easier said than done.
Doctors typically look for a BMI of 30 or higher, or 27+ with a related condition like diabetes or high blood pressure. They’ll also review your medical history and check for issues like pancreatitis or thyroid disease before writing a prescription.
From there, you’ll have to navigate insurance approval, which is a whole other battle. Many providers and plans will call for documentation of prior weight-loss attempts or extra paperwork for authorization. Otherwise, you’re stuck paying out of pocket. Speaking of which…
Cost Comparison
Finally, you need to think about the cost of GLP-1 to choose between Wegovy vs Zepbound. Monthly costs typically fall between $1,000 and $1,300 without insurance, regardless of the name-brand drug you get prescribed.
Results require ongoing use, as we talked about above. Ongoing use means long-term cost is a real consideration for anyone exploring these treatments. This is why so many people end up looking towards more natural options before committing to GLP-1 drugs.
So is Zepbound Better Than Wegovy, or the Other Way Around?
All that being said, is Zepbound better than Wegovy? Or, is it the other way around? It’s impossible to say, really, without knowing your goals and how your body will respond. Both can deliver real weight loss results.
Zepbound may have a slight edge in total weight loss for some people because it activates two hunger-related hormone pathways instead of one. That being said, Wegovy has a longer track record and more data behind it.
Ultimately, your doctor will help you figure out which of these GLP-1 drugs makes the most sense. In the meantime, we hope this Zepbound vs Wegovy comparison has left you feeling clear on the most important differences!
