TribeTeam
At TribElle, we know that everyone's weight management journey is unique. Some of our patients start on Mounjaro (Tirzepatide) and later consider switching to Wegovy (Semaglutide), whether due to cost, supply, personal preference, or clinical reasons. Here's everything you need to know to make the switch safely and confidently.
Key Takeaways
- Always start Wegovy from the lowest dose (0.25mg), even if you were established on a higher Mounjaro dose
- No washout period is needed between the two medications
- Your next injection day stays the same, you simply switch the medicine
- Titrate up gradually for the best safety and tolerance outcomes
Why Do I Have to Start From the Lowest Dose?
Even if you have been taking Mounjaro, Wegovy works differently in the body. Tirzepatide (Mounjaro) targets two hormones, GIP and GLP-1, while Semaglutide (Wegovy) targets GLP-1 only. That means your system needs time to adjust to a new mechanism, regardless of how long you have been on treatment.
🛡️
Safety First
Helps your body tolerate semaglutide safely and in line with its licensed guidance
🌿
Fewer Side Effects
Reduces the risk of nausea, bloating, and changes in bowel habits that can come with jumping doses
📋
Clinically Supported
Follows Wegovy's licensed titration schedule, based on extensive clinical trial data
How the Switch Works
The good news? It is simpler than you might think. There is no washout period needed, and your injection day stays exactly the same.
1
Take Your Last Mounjaro Dose as Planned
No need to stop early or skip a dose. Carry on as normal.
2
Start Wegovy 0.25mg on Your Next Injection Day
If your last Mounjaro was on a Sunday, your first Wegovy is the following Sunday.
3
Follow Wegovy's Titration Schedule
Increase your dose gradually based on how your body responds and your clinical plan.
Wegovy Titration Schedule
| Weeks 1-4 | 0.25mg weekly |
| Weeks 5-8 | 0.5mg weekly |
| Weeks 9-12 | 1mg weekly |
| Weeks 13-16 | 1.7mg weekly |
| Week 17 onwards | 2.4mg weekly (maintenance) |
Your clinical team may adjust this schedule based on your individual tolerance and response.
What to Expect When Switching
Everyone responds differently. Some patients find the switch completely smooth, while others notice changes in appetite suppression or mild side effects as their body adapts to the new medicine.
Most common side effects during the switch include nausea, bloating, constipation, or diarrhoea. These usually ease as your body adjusts, especially when titrating gradually.
💡 Starting at 0.25mg is about safety, not starting over. Your body already knows how to respond to GLP-1 medicines. The titration simply helps maintain tolerability on a new one.
Frequently Asked Questions
Do I need to stop Mounjaro before starting Wegovy?
No. Simply take your last Mounjaro dose as planned, and begin Wegovy on your next scheduled injection day. There is no washout period needed.
Will I lose progress if I start back at 0.25mg?
Not at all. Starting at the lowest dose is about safety, not starting over. Your body already knows how to respond to GLP-1 medicines, and the gradual titration simply helps maintain tolerability on the new medication.
Can I jump to a higher Wegovy dose since I was already on Mounjaro?
No. Even if you were established on a higher Mounjaro dose, Wegovy acts differently in the body. Skipping the titration steps could increase side effects and is not recommended by our clinical team.
