Switching from one weight loss treatment to another can feel daunting, especially if you are unsure how to do it and whether it is even possible.

In the article, we’ll look into the differences between Mounjaro and Wegovy, the reasons why you might consider switching, and whether you’re eligible to switch. We’ll also provide you with a clear guide on how to switch safely, as well as answers to other frequently asked questions to help you make an informed decision.

Key Takeaways

Here are the five biggest takeaways from this article about switching from Wegovy to Mounjaro:

• While both medications are effective for weight loss, Mounjaro contains tirzepatide, which has shown greater weight loss potential in some clinical trials, whereas Wegovy contains semaglutide.

• To switch between Wegovy and Mounjaro, you must meet the criteria for both medications, including a BMI of 30 or higher (or 27–30 with a weight-related condition).

• Switching involves stopping Wegovy under medical supervision, waiting for five weeks to allow the active ingredient to leave your system and then starting Mounjaro at the lowest dose to minimise side effects.

• Withdrawal symptoms are not typically expected when switching, but a break between medications may cause appetite to return to pre-treatment levels.

• Both medications are prescription-only and require careful planning when switching to avoid overlapping effects or side effects.

What are the differences between Mounjaro and Wegovy?

Mounjaro and Wegovy are both prescription medications used to support weight loss when combined with a healthy diet and regular exercise, however, there are several differences between them. Mounjaro contains tirzepatide as its active ingredient, while Wegovy uses semaglutide. Tirzepatide, in some clinical trials, has been shown to be more effective than semaglutide, although results will vary from person to person [1].

Both medications follow dosing schedules that gradually increase. This is the case as it helps to minimise side effects, which can include nausea, diarrhoea and constipation. Below is a handy table you can use to compare the two medications:

Other Brand Names For Wegovy and Mounjaro

Wegovy and Mounjaro are primarily known as weight loss medications, but their active ingredients are also used in treatments designed for managing type 2 diabetes. The active ingredient in Wegovy, semaglutide, is also found in Ozempic. 

You may have heard of Ozempic as a weight loss medication. This is because it can treat weight loss in countries such as the United States. This is NOT the case in the UK, as it is not licensed for weight loss. Instead, Ozempic is used as a medication to treat type 2 diabetes. It’s important to note that Wegovy is specifically approved for weight loss, making it the recommended option. Ozempic for type 2 diabetes can be purchased online from UK Meds.

Mounjaro, on the other hand, is licensed to treat type 2 diabetes as well as weight loss. In some countries, Mounjaro is available as generic tirzepatide, which can be used to treat type 2 diabetes and weight loss.

Why would I consider switching from Wegovy to Mounjaro?

There are several reasons you might consider switching from Wegovy to Mounjaro. Clinical trials suggest that Mounjaro can deliver better weight loss results than Wegovy. Although both medications are thought to be highly effective, some people are more drawn to Mounjaro for the potential for better results.

Other people may be interested in switching simply to try something new, especially if they’ve not had the results they expected when using Wegovy or if they have experienced adverse side effects from semaglutide. Whatever your reason for switching, your doctor can help determine whether it is right for you.

Am I eligible to switch?

You may be eligible to switch from Wegovy to Mounjaro if you meet the criteria for both medications. Typically, this includes having a body mass index (BMI) of 30 or higher or a BMI between 27 and 30 if you have a weight-related condition such as prediabetes. You should also consult with your doctor before changing your treatment. They will ensure you don’t have any pre-existing medical conditions or allergies to the active ingredients that could make these medications unsuitable for you.

You must be over 18 years old, not pregnant or breastfeeding, and not taking any medications that might interact with Mounjaro. If you meet these requirements, your doctor can advise whether switching is the right option for you.

How do I switch from Wegovy to Mounjaro?

Switching from Wegovy to Mounjaro should be done carefully and always under the supervision of a healthcare professional. The first step in the process is to stop taking Wegovy. Your doctor will help you decide when and how to stop using the medication.

After you stop using Wegovy, you’ll typically go through a “wash-out” period. This usually lasts a few weeks, allowing the Wegovy to leave your system before starting Mounjaro. The exact time it takes can vary.

Once your doctor is satisfied the wash-out period is complete, you’ll start your treatment with Mounjaro. Your doctor will start you on a lower dose to help your body adjust to the new medication. Similar to Wegovy, your dose will increase over several weeks or months to reach the maintenance level. When you reach the maintenance dose of Mounjaro, you’ll continue with this dosage for the rest of your treatment.

Switching weight loss medications is a big decision that should be carefully considered. Communication with your doctor about your experiences, goals, and any side effects is vital.

How to stop Wegovy

Stopping Wegovy should always be done under the supervision of a doctor to make sure you stay safe. Your doctor will guide you through the process, which may vary depending on your current dose and how your body has reacted to the medication.

In most cases, you’ll be advised to gradually decrease your dose over several weeks. This helps minimise the risk of withdrawal or side effects that could happen if you stop using the medication too quickly. If you’ve experienced significant while on Wegovy, your doctor may recommend reducing the medication more slowly to give your body extra time to adjust.

It is important to remember that Wegovy is still an effective weight loss medication that could provide you with excellent results. You can buy Wegovy online from UK Meds.

How to start Mounjaro

Starting Mounjaro after switching from Wegovy should always be done under the guidance of your doctor. They will provide personalised advice to ensure a safe transition. Follow their instructions carefully to minimise the risk of side effects and allow your body to adjust to the new medication.

Typically, you will begin Mounjaro at the lowest dose of 2.5mg, taken once a week for the first four weeks. This initial low dose is designed to help your body get used to the medication while reducing the likelihood of side effects.

FAQS About Switching From Wegovy To Mounjaro

Can you use both medications interchangeably?

No, Mounjaro and Wegovy are not interchangeable, and it’s important not to use them without proper breaks or at the same time. While both medications are used for weight loss and work in similar ways, they contain different active ingredients that work slightly differently in the body.

Switching between the two medications without medical supervision or using them together could be dangerous and significantly increase the risk of side effects. If you are considering changing from one medication to another, always consult your doctor to ensure you stay safe.

Can you switch from semaglutide to Mounjaro?

Yes, you can switch from semaglutide to Mounjaro, as semaglutide is the active ingredient in Wegovy. This process is the same as switching from Wegovy to Mounjaro and should always be done under the supervision of a doctor to ensure safety and effectiveness.

Are withdrawal symptoms possible when switching?

Withdrawal symptoms are not typically expected when switching from Wegovy to Mounjaro. While you can stop taking Wegovy without the need to taper your dose, there may be a break between medications during which the effects of Wegovy begin to wear off.

During this time, you may notice your appetite returning to how it was before you started Wegovy. This is not the same as experiencing withdrawal symptoms, it’s just the medication’s effects diminishing as it leaves your system. If you have concerns, your doctor can provide guidance to help manage any changes you might feel during the switch.

Is there a recommended time to wait before switching?

Yes, it is recommended to wait at least five weeks after finishing Wegovy before switching to Mounjaro. This period allows your body time to clear the active ingredient, semaglutide, from your system before starting a new treatment. This also helps to reduce the risk of side effects from overlapping the effects of the two medications.

Final Thoughts

Switching from Wegovy to Mounjaro is a process that should always be carefully managed with the guidance of a healthcare professional. While both medications are effective for weight loss, they contain different active ingredients and work slightly differently in the body. This makes it crucial to follow a safe transition plan that includes stopping Wegovy, observing a period of at least five weeks and gradually starting Mounjaro at a low dose. Remember, open communication with your doctor is key to making an informed decision that supports your weight loss goals.
