Tirzepatide maintenance dose after weight loss: what the FDA label lists, what two trials found, and how this clinic’s schedule works.
The tirzepatide maintenance dose after weight loss is the dose you stay on to keep the weight off, and the FDA-approved Zepbound label lists 5 mg, 10 mg or 15 mg once a week as the maintenance options. Two large trials found that people who stopped tirzepatide regained much of the weight, and that staying on treatment kept it off.
This article is general information, not medical advice or a dose recommendation. Your prescribing provider sets your dose, and nobody should change or stop a dose on their own.
What is the maintenance dose of tirzepatide?
The maintenance dose is the weekly dose you reach after the step-up period and then continue. On the brand-name product, Zepbound, the FDA-approved label sets out the schedule:
- The starting dose is 2.5 mg once a week for 4 weeks.
- After at least 4 weeks, the dose goes up in 2.5 mg steps until the recommended maintenance dose is reached.
- The recommended maintenance dose for weight reduction and long-term maintenance is 5 mg, 10 mg or 15 mg once a week.
- The label tells prescribers to consider treatment response and tolerability when choosing the maintenance dose. The maximum is 15 mg once a week.
The label also describes the medicine as being used with a reduced-calorie diet and increased physical activity, to reduce excess body weight and to maintain weight reduction long term. So “maintenance” is not a separate drug or a finish line. It is the same medicine, at the dose that works for you, continued.
How does this clinic’s schedule handle maintenance?
The clinic’s published tirzepatide schedule moves in this order: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg and 15 mg, which is the maximum. We explain every step in our guide to the starting dose of compounded tirzepatide. The clinic’s published rule has two parts:
- Stay if it is working. If the medication is curbing your appetite and you are losing weight, you stay at your current dose for as long as it keeps working.
- Move up only if it is not. The dose is only increased after at least two weeks, and only if the medication is not working and is not causing serious side effects.
In practice, that means the clinic’s maintenance dose is the dose you are on when it is working. A higher number is not a better result in itself. The schedule is a ladder with the right rung for you, not a countdown to 15 mg. If you want to see what a dose looks like on a syringe, our guide to tirzepatide units by vial strength explains how the numbers work.
| Brand-name label | This clinic’s published schedule | |
|---|---|---|
| Starting dose | 2.5 mg once a week for 4 weeks | 2.5 mg once a week |
| Step size | 2.5 mg, after at least 4 weeks | 2.5 mg, after at least 2 weeks, only if it is not working |
| Maintenance | 5 mg, 10 mg or 15 mg | Your current dose, as long as it works |
| Maximum | 15 mg once a week | 15 mg once a week |
Do not mix the two schedules yourself. Ask your prescribing provider which one applies to you.
What happens to your weight if you stop tirzepatide?
The clearest answer comes from a trial called SURMOUNT-4, published in JAMA. The design was simple:
- 783 adults with obesity or overweight took tirzepatide at their maximum tolerated dose (10 mg or 15 mg) for 36 weeks.
- Those who completed this period lost 20.9% of their body weight on average.
- 670 of them were then randomly chosen to either continue tirzepatide or switch to a placebo for another 52 weeks, alongside diet and physical activity.
From week 36 to week 88, people who continued tirzepatide lost a further 5.5% of their weight on average. People switched to placebo regained 14.0%. At the end, 89.5% of those who continued had kept at least 80% of their weight loss, compared with 16.6% of those on placebo. The authors concluded that withdrawing tirzepatide led to substantial regain, while continued treatment maintained and added to the initial weight loss.
These are averages from a trial. They do not predict what will happen to you, and they do not mean you should never stop. They show why stopping is a decision to make with your provider, not on your own. A later analysis of the same trial, in JAMA Internal Medicine, looked at the health measures that moved with weight regain, including waist size and blood pressure.
Does lowering the dose keep the weight off?
A newer trial asked exactly this question. SURMOUNT-MAINTAIN, published in The Lancet in 2026, followed adults for 52 weeks after a 60-week weight-loss period on 10 mg or 15 mg. They were randomly assigned to one of three paths:
| Path after weight loss | Average body weight vs the start of the trial (week 112) |
|---|---|
| Continue the maximum tolerated dose (10 mg or 15 mg) | About 22% lower |
| Reduce to 5 mg | About 17% lower |
| Switch to placebo | About 10% lower |
Figures are rounded from the model-based estimates in the published abstract. The Lancet later published a correction to this paper, so check the journal for the final numbers.
The authors wrote that reducing to 5 mg might be a valuable alternative to stopping, although each person’s response may differ. People who regained at least half of their lost weight were offered rescue treatment, and that was needed far more often after switching to placebo than after continuing or reducing the dose.
This is research, not a recommendation to lower your dose. Whether a lower dose makes sense for you depends on your weight, your health, how you tolerate the medicine, and what your provider advises.
Do these results apply to compounded tirzepatide?
Not directly. Both trials tested the brand-name product, and both were funded by the manufacturer. The FDA states that compounded drugs are not FDA-approved, which means the agency does not review them for safety, effectiveness or quality before they are sold. So the trial results show what to expect from the studied medicine. They cannot be assumed to carry over to a compounded product.
The ideas that do carry over are practical ones: weight regain after stopping is common, and a maintenance plan should be agreed in advance. For the clinic’s current programs, see the tirzepatide programs page.
What should you ask your provider about maintenance?
Bring these questions to your next appointment:
- Is my current dose still working, and how will we know?
- If my weight has levelled off, should I stay on this dose?
- If I want to change my dose, what are the risks of going lower or stopping?
- How will we watch my weight, waist size and blood pressure over time?
- What is the plan if weight starts to come back?
- What side effects should make me call you before my next dose? Our page on GLP titration side effects explains the common ones.
If you are on the weekly schedule and miss an injection, follow the instructions your own prescriber gave you. The brand-name label has its own missed-dose rules, which are not a substitute for that advice.
Frequently asked questions
What is the maintenance dose of tirzepatide?
On the brand-name Zepbound label, the recommended maintenance dose for weight reduction and long-term maintenance is 5 mg, 10 mg or 15 mg once a week, with 15 mg as the maximum. Your prescribing provider decides which dose is right for you.
Do you have to stay on tirzepatide forever?
There is no rule that says so, but the evidence suggests weight often returns after stopping. In the SURMOUNT-4 trial, people switched to placebo regained 14.0% of their body weight on average over 52 weeks. Whether and when to stop is a decision for you and your provider.
Can you lower the tirzepatide dose after losing weight?
A 2026 trial in The Lancet tested reducing to 5 mg after weight loss and found it kept more weight off than switching to placebo, though less than staying on the maximum tolerated dose. Do not lower your dose without your provider’s guidance.
What happens if you stop tirzepatide?
In SURMOUNT-4, people who switched to placebo after 36 weeks of tirzepatide regained 14.0% of their body weight on average, and only 16.6% kept at least 80% of their weight loss. Individual results vary.
Is the maintenance dose different for compounded tirzepatide?
The trials tested the brand-name product, so their results cannot be assumed for compounded tirzepatide, which the FDA says is not FDA-approved. This clinic’s published rule is to stay at your current dose for as long as it is working.
Does a higher tirzepatide dose mean better results?
Not by itself. The brand-name label tells prescribers to consider response and tolerability when choosing the maintenance dose. This clinic’s published rule is to stay at your current dose while it works and to move up only if it is not working and not causing serious side effects.
Do diet and exercise still matter during maintenance?
Yes. The brand-name label describes tirzepatide as used with a reduced-calorie diet and increased physical activity, and the SURMOUNT-4 trial was run alongside diet and physical activity.
