Quick Answer: Switching from Wegovy to Zepbound is possible and often beneficial, thanks to Zepbound's dual hormone action and higher weight-loss potential. The transition should be gradual, starting at a low dose, and always guided by a healthcare provider to minimize side effects and ensure safety.
As Zepbound (tirzepatide) emerges as a groundbreaking treatment for weight loss and obesity, many are considering switching from existing treatments such as Wegovy (semaglutide).
But before making any change, it's important to understand the specifics of both medications. While moving to Zepbound could be a great move for your weight-loss journey, there are many things to consider first, including dosage, side effects, expectations, and suitability.
Let's walk through these considerations together and learn how to make a safe and effective transition from Wegovy to Zepbound.

Switching Between GLP-1s Weight Loss Drugs
Both Zepbound and Wegovy belong to the class of GLP-1 drugs (glucagon-like peptide-1), along with Mounjaro, Ozempic, and others. These medications are mainly used to manage type 2 diabetes and obesity. They primarily work by mimicking the action of the naturally occurring hormone GLP-1, which is involved in regulating blood sugar levels. But GLP-1 drugs also slow gastric emptying and increase feelings of fullness after eating, making them an efficient treatment option for patients with obesity and overweight issues.
Switching between GLP-1 receptor agonist drugs like Wegovy and Zepbound is quite common in the management of obesity and related conditions. However, each has unique properties and effects, making the decision to switch something that should be carefully considered and supervised by your healthcare provider.
So, before we delve into the specifics of switching from Wegovy to Zepbound, let's take a moment to understand what each of these medications is exactly, their shared characteristics, and the differences between them.

What is Zepbound?
Zepbound is the newest prescription injection for weight loss approved by the FDA in November 2023. It contains tirzepatide, which is quite a unique and innovative drug because it targets two hormones at the same time: the GLP-1 hormone, like Wegovy and Ozempic, but also the GIP hormone (glucose-dependent insulinotropic polypeptide). This dual action not only helps reduce appetite but also enhances the body's ability to manage blood sugar and process calories more efficiently, promoting even more substantial weight loss.
Zepbound is approved for chronic weight management in:
- Adults who have obesity with a body mass index (BMI) of 30 kg/m² or higher.
- Adults with overweight (BMI of 27 kg/m² or higher) and at least one weight-related health issue, like hypertension, type 2 diabetes, or dyslipidemia.
It is a weekly subcutaneous injection that you inject yourself at home thanks to an easy-to-use, single dose injector pen. It exists in different dosages from 5 mg to 15 mg. The treatment typically begins with a low starting dose followed by a gradually increased maintenance dose depending on tolerance to the treatment and side effects.
What is Wegovy?
Wegovy has been available since June 2021 and is a prescription medication designed specifically for weight management. Its active ingredient is semaglutide, a GLP-1 receptor agonist that helps regulate appetite and reduce calorie intake.
Unlike Zepbound, which targets two hormones, Wegovy works exclusively by mimicking the GLP-1 hormone. This increases feelings of fullness, slows gastric emptying, and helps reduce overall food intake. While many users have found it effective, it may not work for everyone, especially those who experience side effects or limited weight loss.
FDA Approval and Indications:
Wegovy is approved for chronic weight management in adults who are:
-
Obese (BMI ≥ 30), or
-
Overweight (BMI ≥ 27) with at least one weight-related health condition such as:
-
High blood pressure
-
Type 2 diabetes
-
High cholesterol (dyslipidemia)
-
Administration and Dosage:
-
Wegovy is a once-weekly subcutaneous injection.
-
It comes in a pre-filled pen designed for easy self-injection at home.
-
Treatment usually:
-
Begins with a low dose to reduce the risk of side effects like nausea
-
Increases gradually over several weeks to reach the target dose
-
This stepwise approach helps improve tolerability and minimize side effects common to GLP-1 drugs

Is Zepbound better than Wegovy?
Not necessarily. While Zepbound has shown greater weight-loss results in clinical trials, with up to 22% weight loss compared to 16% for Wegovy, it does not necessarily mean that it is "better" than Wegovy.
When considering whether Zepbound is better than Wegovy, the clinical results aren't the only factor to look at. The choice between Zepbound and Wegovy may also depend on:
- Individual health conditions. For instance, patients with specific metabolic issues may find the additional GIP receptor activity in Zepbound offers better control over blood sugar levels. Besides, both medications come with contraindications for certain medical conditions.
- Side effects. While both medications share common side effects like nausea and diarrhea, the intensity and occurrence can vary a lot between individuals. Some people may experience more side effects with Wegovy and find relief in Zepbound while the opposite may be true for others.
- Response to treatment. Some patients may lose more weight with Zepbound while others may respond better to Wegovy.
Ultimately, whether or not you should switch to Zepbound must be considered with your healthcare provider.

How to Switch from Wegovy to Zepbound
So, you've been on Wegovy for quite some time now and are considering a switch to Zepbound to see if it works better for you? You're not alone! Many are turning to Zepbound, intrigued by its recent launch and high potential for better weight-loss results.
But while the idea of switching weight-loss injections might be exciting, it's crucial to handle the transition thoughtfully. From understanding how each treatment works to managing dosages and expectations, the transition must be done under medical supervision to ensure your switch is as smooth and effective as possible.
Both Wegovy and Zepbound are administered via weekly subcutaneous injections, making the switch somewhat easier.
However, because they act on different hormonal pathways, the transition must be gradual to minimize any disruptions in therapy or side effects. That's why when switching from Wegovy to Zepbound, your doctor will likely advise you to taper off Wegovy while gradually introducing Zepbound. This helps your body adjust to the new medication without overlapping effects that could increase side effects.
Stop Wegovy Before You Start Zepbound
It's important to stop taking Wegovy before you begin your Zepbound injections to prevent overlapping effects that could increase side effect risks. It is not recommended to take Zepbound and Wegovy or any other GLP-1 drugs together.
Follow your doctor's guidelines. Some recommend starting Zepbound the week after your last Wegovy injection, while others may need a few weeks in between the two medications.
Begin with a Low Dose of Zepbound
When switching to Zepbound, treatment typically starts at the lowest dose to help your body adjust and minimize side effects.
Typical Dosage Progression:
-
Starting dose: 0.25 mg per week (usually for the first 4 weeks)
-
After 4 weeks: Increased to 5 mg once a week
-
Ongoing adjustments:
-
Dose may be increased in 2.5 mg increments every 4 weeks
-
Alternatively, your doctor may reduce the dose if needed based on tolerance and side effects
-
Important Notes:
-
The maximum recommended dose of Zepbound is 15 mg per week, but not everyone needs or reaches this dose.
-
This gradual, step-by-step approach:
-
Helps your body adapt to the new medication
-
Allows your doctor to monitor your response closely
-
Reduces the risk of tirzepatide-related side effects
-
Be Prepared for a Trial Period:
-
Finding the right dose often takes time and may involve some trial and error
-
This process can be frustrating and may delay visible results, but it's key to finding the safest and most effective dose for you
Maintain a Balanced Diet and Regular Exercise
Achieving the best weight-loss results from Zepbound involves more than just medication-it requires a healthy diet and regular physical activity. Work with a healthcare provider to create a personalized diet and exercise plan that includes a variety of nutritious foods and at least 150 minutes of moderate exercise per week.

Prepare for Initial Side Effects
While Zepbound and Wegovy have similar safety and side effect profile, you may be more sensitive to one or the other medication. It means that if you may suffer from side effects, mainly gastrointestinal ones, from Zepbound while you had none with Wegovy. The other way around, you may feel much better on Zepbound than on Wegovy.
Side effects with Zepbound are quite common, especially at the beginning of the treatment.

Explore Alternative Weight-loss Treatments If Needed
If Zepbound doesn't meet your needs, or if you experience intolerable side effects, remember that other GLP-1 receptor agonists or weight management options are available.
Typically, a minimum of 5% weight loss within the first three months of taking Zepbound considered a sign of effectiveness. If this benchmark isn't met, Zepbound may not be the right medication for you. So, don't hesitate to share your doubts with your doctor to explore alternative weight-loss treatments.
FAQs About Switching from Wegovy to Zepbound
Can You Take Wegovy and Zepbound Together?
No, it's not recommended to take Wegovy and Zepbound together. Because they belong to the same class of drugs and act in similar ways, combining them can increase the risk of side effects without offering additional benefits. A proper transition plan should be followed when switching between these medications to make sure their effects do not overlap.
How long does it take to see results from Zepbound after switching?
The time it takes to see results from Zepbound after switching from another weight loss medication like Wegovy can vary. Some patients may begin to notice weight loss or reduced appetite within the first few weeks of starting Zepbound.
However, significant results are generally observed after two to three months of consistent use. That being said, individual results vary a lot and don't depend on the medication alone. Your initial weight, diet, exercise, and personal metabolic rate have a great impact too.
Can I switch back to Wegovy if Zepbound doesn't work for me?
Yes, you can switch back to Wegovy if Zepbound does not meet your expectations or if the side effects are too much for you.
However, this decision should always be made in consultation with your doctor. Like switching from Wegovy to Zepbound, switching the other way around requires careful planning and medical monitoring. Repeatedly changing medications may affect your body's response to treatment.
Will my insurance cover Zepbound if I switch from Wegovy?
Insurance coverage is a common concern when switching from Wegovy to Zepbound. Weight-loss injections aren't always covered by health insurance. However, if your insurance previously covered your Wegovy prescription, chances are they will cover Zepbound too. Especially since Zepbound is quite cheaper than Wegovy, with a list price of $1,059 for a month's supply compared to $1,349 for Wegovy.
