Maintenance Dosing with Tirzepatide and Semaglutide: What the data tells us.

THIS IS NOT SPECIFIC MEDICAL ADVICE IN THIS BLOG POST. THIS IS FOR INFORMATIONAL PURPOSES ONLY.
As a plastic surgeon offering comprehensive medical weight loss services in Austin, I frequently work with patients using GLP-1 medications like semaglutide (Ozempic®, Wegovy®) and tirzepatide (Mounjaro®, Zepbound®). These medications have transformed the way we approach weight management, helping patients lose significant amounts of weight safely and sustainably.
One of the most common questions I hear is:
“Once I’ve reached my goal weight, what’s next? Do I have to stay on the medication forever?”
The truth is, there’s no single answer for everyone — but research has given us important insights about maintenance dosing and how to set yourself up for long-term success.
WHY MAINTENANCE MATTERS
GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptor agonists work by:
- Slowing gastric emptying, so you feel full longer
- Reducing hunger signals in the brain
- Improving insulin sensitivity and blood sugar control
These effects are powerful for weight loss, but they don’t permanently “reset” your metabolism. If the medication is stopped suddenly, hunger and cravings often return, and the body’s natural defense mechanisms against weight loss — like a slower resting metabolism — can make regaining weight almost inevitable.
A maintenance dose is designed to keep these beneficial effects in place while minimizing side effects and medication costs.
WHAT RESEARCH SHOWS ABOUT STOPPING THE MEDICATIONS
Several major studies have examined what happens when patients stop taking semaglutide or tirzepatide:
STEP-1 Trial (Semaglutide):
Participants treated with semaglutide 2.4 mg weekly lost ~17% of body weight over 68 weeks. When treatment stopped, they regained two-thirds of their weight loss within one year, demonstrating how quickly the body can revert without ongoing support.

SURMOUNT-1 Trial (Tirzepatide):
Patients taking tirzepatide 5, 10, or 15 mg weekly lost 15–21% of body weight over 72 weeks compared to just 3% with placebo.
SURMOUNT-4 Randomized Withdrawal Study:
After an initial weight loss phase, participants were either kept on tirzepatide or switched to placebo.
Those who continued medication maintained or furthered their weight loss, while those who stopped experienced significant regain.
Key takeaway:
- Maintenance dosing dramatically improves your chances of keeping the weight off. Stopping treatment suddenly often leads to rapid regain, even when strong lifestyle habits are in place.
For those who want to dive deeper into the data, additional long-term studies like STEP-5 (two-year semaglutide trial) are showing similar results but are not complete or publishes as of September 2025.
WHEN TO TRANSITION TO MAINTENANCE DOSING
In my practice, I typically consider maintenance dosing when a patient:
- Has achieved 70–90% of their target weight loss goal
- Has had stable weight for at least 4–6 weeks
- Has built sustainable diet and exercise habits during the active weight loss phase
At this point, we carefully taper down to find the lowest effective dose that prevents hunger and weight regain. We also can adjust the frequency perhaps to every other week or even less frequent in some patients.
If you’ve recently completed a major weight loss journey, you may also be considering body contouring procedures like a tummy tuck or mommy makeover to address loose skin and achieve your ideal silhouette. When the weight loss has stabilized over 3-6 months it may be time to consider those surgeries.
But....
Remember we would need to hold the medications prior to procedures that would require general anesthesia for at least a week so that needs to be taken into account for maintenance dosing.
TYPICAL MAINTENANCE DOSE RANGES
Note: Always follow a plan created by your prescribing provider. This is not specific and only for educational purposes.
Semaglutide (Wegovy® / Ozempic®)
- Standard weight loss dose: 2.4 mg weekly
- Typical maintenance dose: 0.5 – 1.7 mg weekly
- Some patients may maintain results on as low as 0.25 mg weekly, though this varies greatly.
Tirzepatide (Mounjaro® / Zepbound®)
- Standard weight loss dose: 10 – 15 mg weekly
- Typical maintenance dose: 5 – 7.5 mg weekly
- Some patients stabilize at 2.5 mg weekly, particularly when lifestyle factors are strong.
The goal of maintenance dosing is to minimize medication while still supporting appetite control and metabolic stability.
TIPS FOR SUCCESS WHILE ON MAINTENANCE DOSING
Transitioning from active weight loss to long-term maintenance is as much mental and behavioral as it is physiological. Here are the strategies I recommend to my patients:
- Prioritize Protein - Aim for 80–120 grams of protein daily, depending on your size and activity level. Protein preserves lean muscle mass, which is crucial for maintaining your metabolism.
- Strength Train Regularly - GLP-1 medications can result in loss of both fat and muscle. Strength training 2–3 times per week helps maintain lean tissue and tone your body.
- Monitor Weight Weekly - Small weight fluctuations are easier to correct than large ones. If you notice a 2–3 pound upward trend, it may be time to adjust your dose or habits.
- Optimize Sleep and Stress Levels - Poor sleep and high stress raise cortisol, which can increase cravings and fat storage. Aim for 7–9 hours of sleep nightly and use mindfulness or meditation to manage stress.
- Stay Hydrated - Dehydration can feel like hunger. Drink plenty of water throughout the day, especially before meals.
CAN YOU EVER STOP MEDICATION COMPLETELY?
For some patients, especially those who have maintained healthy habits for a year or longer, it may be possible to gradually wean off medication. However, this should always be done under medical supervision.
Even after successfully stopping, some patients benefit from occasional “booster cycles” of treatment to maintain results — similar to returning to physical therapy after an injury.
If weight regain occurs, restarting your program at our medical weight loss clinic is a straightforward process.
THE ROLE OF ONGOING MEDICAL SUPERVISION
GLP-1 medications are powerful tools, but they aren’t a magic solution. Long-term success comes from combining medication with:
- Personalized nutrition guidance
- Tailored exercise plans
- Regular follow-up visits to monitor lab work and adjust dosing as needed
At Levesque Plastic Surgery, we take a whole-patient approach. Many of our patients also pursue aesthetic procedures like breast augmentation or facelifts after weight loss to further enhance their confidence and results.
BOTTOM LINE: What the Data Tells Us
- Stopping semaglutide or tirzepatide abruptly almost always leads to weight regain.
- Maintenance dosing, even at a lower level, dramatically improves long-term outcomes.
- Sustainable success requires nutrition, exercise, and behavioral support, not just medication.
- With the right plan, many patients can eventually reduce or even stop medication while maintaining their results.
