Switching between treatments doesn’t mean starting over — it’s about continuing your progress with confidence and expert support. At Curate, your safety and weight loss journey are our priority. Every transition is overseen by a prescriber who will design a Wegovy plan tailored to your treatment history, tolerance and goals.
Your Personalised Transition Plan
Mounjaro (tirzepatide) and Wegovy (semaglutide) act differently in the body, so there is no direct milligram-for-milligram conversion. Our prescribers use recognised clinical guidance to determine the safest and most effective starting dose for you. When creating your plan, we consider:
- Your current Mounjaro dose and treatment duration
- How well you tolerated therapy, including gastrointestinal side effects
- Your weight management progress and goals
Overall health and other medications
A Short Pause Before Starting Wegovy
To ensure a safe transition, you will usually wait 7 days after your final Mounjaro injection before starting Wegovy. This interval allows Mounjaro to clear your system and reduces overlapping effects.
Mounjaro contains the active ingredient tirzepatide which mimics two hormones - GLP-1 and GIP. This helps to regulate blood sugar levels, reduce cravings and enhance feelings of fullness; the action of the two hormones combined can mean a stronger effect. All of these actions result in weight loss.
Wegovy contains the active ingredient semaglutide which mimics the hormone GLP-1. This helps to regulate appetite and food intake. It does not mimic GIP and therefore weight loss can be slower.
Because Wegovy binds strongly to GLP-1 receptors, some patients may notice stronger gastrointestinal side effects at first, such as:
- Nausea
- Vomiting
- Diarrhoea
- Constipation
These are usually mild and temporary. Strategies to minimise discomfort include smaller, lighter meals, avoiding rich or fatty foods, and staying hydrated. Contact your Curate clinical team if symptoms persist or become difficult to tolerate.
Choosing your dose
Option 1: Starting at the lowest Wegovy dose
- Recommended if you experienced gastrointestinal side effects on Mounjaro.
- Allows your body to adapt gradually and reduces the likelihood of side effects returning.
Option 2: Starting at a higher Wegovy dose
- Appropriate if you tolerated Mounjaro well with minimal side effects.
- Helps maintain treatment momentum and appetite control without restarting at the lowest strength.
- You may be more likely to experience side effects
Evidence and clinical experience support higher starting doses for patients with prior GLP-1 tolerance, allowing for more rapid continuation of therapy while maintaining safety.
Your prescriber will review both options and decide the best approach for your comfort, safety, and goals.
Typical Starting-Dose Guidance
While there is no direct equivalent dose when switching medication, however our prescribers useclinical experience and available studies to guide dosing. Your exact starting dose will always be confirmed after a full review.
What to Expect After Switching
As your body adjusts to Wegovy, you may notice:
- Appetite changes — suppression may feel less than with Mounjaro
- Mild GI symptoms — nausea, constipation or diarrhoea may occur, especially after dose increases
- Weight loss pace — may initially be slower, but long-term results are comparable with consistent treatment
Serious side effects are rare, but seek prompt medical attention for severe abdominal pain, especially if accompanied by nausea, vomiting, jaundice or fever.
Supporting Your Transition
To adapt comfortably:
- Eat smaller, balanced meals
- Drink water regularly
- Maintain gentle daily activity
Track side effects and share with your Curate team
Ongoing Care with Curate
Your Wegovy dose typically increases every four weeks, if well tolerated, until reaching a maintenance dose that supports long term appetite control and weight management. Our clinical team will monitor progress, review response and adjust your plan to ensure safe, steady results.
