Can I start herbal diet medicine right after stopping Mounjaro?
When to start herbal diet medicine after stopping Mounjaro or Wegovy
At ACRO Korean Medicine Clinic, we start herbal diet medicine once 1 week has passed since your last Mounjaro or Wegovy injection. Please decide when to stop with the clinic that prescribed your injections first, and tell us the date of your last injection so we can set your start date around it.
Why do the first months after stopping matter?
In the SURMOUNT-MAINTAIN study, published in the Lancet in 2026, people who had lost weight on Mounjaro were split into three groups and followed for one year. All three groups received the same diet and exercise counseling, yet the results differed widely.
| After weight loss | Weight loss remaining after 1 year |
|---|---|
| Stayed on high dose | 96.5% |
| Lowered to 5mg | 67.9% |
| Stopped (placebo) | 42.8% |
Even with the same counseling, depending on what they continued after losing weight, their weight one year later differed this much. That is why we recommend deciding on your next step before you stop.
I'm on injections now. Can I take it at the same time?
If you would like to take both, we decide together at your visit. We look at the injection you use, its dose and schedule, the medicines you take and your health, and discuss with you whether to take them together or start after you finish the injections. Pyeonan Pill, which eases constipation, can be taken while you are still on injections.
If you had discomfort while on injections
Please tell us at your consultation about any symptoms you had while on injections, such as nausea or vomiting, bloating, constipation or diarrhea, fatigue, dizziness or sleep problems. We take those into account when planning your prescription, and adjust it right away if any discomfort appears while you take it.
At ACRO
For the first 3 months after stopping, we see you every month and check your appetite and weight together. The cost is the same as the herbal diet medicine program: ₩270,000 for 1 month and ₩580,000 for 3 months. If you live far away, you can have a telemedicine consultation and receive the medicine by delivery (same cost). See After GLP-1 See S-Capsule
