Can I switch from Wegovy to Mounjaro?
When deciding between Wegovy and Mounjaro for weight loss, there are various factors to consider that may prompt a change in your weight loss approach.
Weight-loss treatments have varying effects on individuals, and what works for one person may not necessarily work for another. If you are suffering from side effects and are not experiencing any weight loss even at the highest prescribed dose of semaglutide (Wegovy) , switching to Tirzepatide (Mounjaro) might be worth considering.
If you have experienced adverse effects from Wegovy, transitioning to Mounjaro could be an alternative. Although both medications share common side effects, their compositions differ in that Wegovy, manufactured by Novo Nordisk, is solely a GLP-1 receptor agonist; Mounjaro, produced by Eli Lilly, is both a GLP-1 and GIP receptor agonist and the first of its kind in obesity and weight management.
It is crucial to remember that both drugs should be used alongside a low-calorie diet and regular exercise for optimal results.
Clinical trials suggest both medications are safe and effective for weight management, but they found that Mounjaro appears to be more effective than Wegovy when it comes to the total amount of weight lost.
Doses
Another factor when considering switching from Wegovy to Mounjaro are the doses. Wegovy has 5 different strengths, while Mounjaro has 6. They are both once-weekly injections, and you should follow the dosing schedule until you find the dose most suited to you.
With Mounjaro, you must start on the lowest dose at 2.5mg and it is important to remember that if a lower dose is effective, there will be no need to increase. If you have already been taking Wegovy and wants to swap to Mounjaro, depending on the dose of Wegovy you may be able to start Monujaro on a higher dose but this will be discussed following your approved consultation form.
Switching treatments
Do not stop or start any medication without speaking to us first, due to the different doses and scheduling, you will need to have stopped taking Wegovy before you start taking Mounjaro but advice will be given to you following your consultation.
Starting Mounjaro
Once you have decided to make the switch, you may need to start Mounjaro on the lowest dose before following the dosing schedule and increasing. It may feel like a set back starting from the beginning but it is important for us to manage your weight loss journey safely. If you increase the dose too quickly, it could lead to adverse side effects, so it is important that you follow the schedule until we find the dose suited to you.

What is the difference between Mounjaro and Wegovy?
Both Mounjaro and Wegovy are safe and effective weight loss medications that help to reduce appetite, curb cravings, and, when used alongside diet and lifestyle factors, help you to lose weight.
Mounjaro
Mounjaro contains the active ingredient Tirzepatide
It is a revolutionary weight-loss injection that offers a clinically proven approach to managing obesity.
It was developed by the pharmaceutical company Eli Lilly.
It is a single use, once-weekly injectable treatment designed to regulate appetite and metabolism, providing a targeted solution for sustainable weight loss.
Mounjaro is indicated for chronic weight management as an adjunct to a reduced-calorie diet and increased physical activity in adults with an initial BMI ≥30 kg/m2 (obesity) or ≥27 kg/m2 (overweight) in the presence of at least one weight-related comorbid condition.
Mounjaro is a glucose-dependent insulinotropic polypeptide (GIP) receptor agonist and glucagon-like peptide-1 (GLP-1) receptor agonist. It is a first in a new class of treatments for weight loss and works by suppressing appetite, making you feel less hungry, resulting in weight loss.
Wegovy
Wegovy contains the active ingredient Semaglutide.
It is a revolutionary weight-loss injection that offers a clinically proven approach to managing obesity.
It was developed by the pharmaceutical company Novo Nordisk.
It is a once-weekly injectable treatment designed to regulate appetite and metabolism, providing a targeted solution for sustainable weight loss.
Until recently, healthcare professionals would prescribe semaglutide under the brand name Ozempic (which is licensed to treat type 2 diabetes) ‘off-label’ to treat obesity.
However, Semaglutide now has an additional product license under the brand name Wegovy, which is specifically licensed for the management of overweight and obesity, so off-label use of ozempic is no longer required.

How long does it take to switch from Wegovy to Mounjaro?
Currently, we do not have specific details regarding the waiting period required between stopping Wegovy and starting Mounjaro.
Wegovy has an extended half-life, which means it may take several weeks for it to completely leave your system, depending on the dosage.
Once we have determined the appropriate timeframe for transitioning from Wegovy to Mounjaro, we will provide you with that information.

It is important to remember to continue to lead a healthy lifestyle with a reduced-calorie diet along with increased physical activity.
How does Mounjaro work?
Similar to Ozempic and Wegovy, Mounjaro works by mimicking the naturally occurring hormone called glucagon like peptide-1 (GLP-1) which is released in the gut in response to food intake and acts as a physiological regulator of appetite.
GLP-1 targets areas of the brain involved in the regulation of appetite and food intake. This can help you eat less, which can lead to weight loss.
Unlike other weight loss medications, Mounjaro is also a Gastric Inhibitory Polypeptide receptor agonist (GIP) which works on another hormone in the body used to help regulate your appetite.
