When Wegovy is stopped, the medicine takes weeks to leave. Semaglutide's elimination half-life is about one week, and the US label says it is present in the circulation for about five to seven weeks after the last injection (US label). What follows over the next year was measured in the STEP 1 extension, where semaglutide and the trial's lifestyle support stopped on the same day, with no taper: people regained about two-thirds of the weight they had lost, on average (Wilding 2022); individual results vary. At GetLean the exit is planned from the first consultation, and Dr Quek steps the dose down at the monthly reviews rather than stopping it at once. This article walks through the first weeks, the first months and the first year, and what the labels and trials show.
Availability in Singapore. This medicine is registered with Singapore's Health Sciences Authority, and its registered indication includes weight management. Which medicine suits a particular person, if any does, is decided by the doctor who assesses them.
What the labels and the STEP 1 extension report about how semaglutide clears, what it does while it is in the body, and the first year after it is stopped.
| Stage | What the labels or trial report | Source |
|---|---|---|
| The first five to seven weeks | An elimination half-life of about one week; present in the circulation for about five to seven weeks after the last injectable dose (US label), or approximately seven weeks after the last 2.4 mg dose (EU label) | US label, EU SmPC |
| While the medicine is in the body | Semaglutide reduces calorie intake, an effect "likely mediated by affecting appetite" | US label |
| The first year | In the STEP 1 extension, adults who had lost 17.3% over 68 weeks stopped semaglutide and the lifestyle programme at once, with no taper; by week 120 they had regained 11.6 percentage points, about two-thirds of the loss, finishing 5.6% below where they started, on average | Wilding 2022 |
The first five to seven weeks: the medicine leaves the body
Semaglutide was built to last a week, so it also takes weeks to clear.
Both labels give an elimination half-life of approximately one week. The US label says semaglutide is present in the circulation for about five to seven weeks after the last injectable dose (US label); the European label says approximately seven weeks after the last 2.4 mg dose (EU SmPC). Both labels tell people planning a pregnancy to stop at least two months beforehand, for the same reason.
So the effect does not end with the last injection. It fades over the following weeks, which is why some people notice little change at first and more later.
Appetite in the weeks after the last dose
The US label says semaglutide reduces calorie intake, and that the effect is "likely mediated by affecting appetite" (US label). As the medicine clears, that effect fades over the following weeks. That is why the eating pattern and the training habit are built while the medication is still working, rather than after it has gone. Appetite after stopping GLP-1 goes into more detail.
The first year: what the STEP 1 extension found
When semaglutide and the lifestyle support stopped on the same day, with no taper, much of the weight came back, but not all of it.
In the STEP 1 extension, adults who had lost 17.3% of body weight over 68 weeks stopped both semaglutide and the lifestyle programme that went with it, at once and with no taper. By week 120 they had regained 11.6 percentage points, about two-thirds of what they had lost, finishing 5.6% below where they started (Wilding 2022).
Those are averages from a studied population, and individual results vary. Some people held most of their loss; others regained more than the average. How much weight comes back after stopping covers what the averages hide.
Stepping down rather than stopping
Neither label gives an instruction on tapering when stopping, and the withdrawal trials stopped treatment outright, with no taper. At GetLean we favour a gradual reduction under a doctor's guidance rather than a cliff-edge stop, which allows appetite to adjust incrementally: Dr Quek steps the dose down at the monthly reviews, towards the lowest effective dose, as the response comes in. Mounjaro or Wegovy maintenance dose covers lower doses, and weaning off GLP-1 how a planned taper works.
Coming off Ozempic
Ozempic is the same molecule at lower doses, registered in Singapore for type 2 diabetes only (NDF). It has no registered weight-management indication here, so prescribing it for weight is off-label: a decision only a doctor who has assessed you can make, and one they may decide against. The trial on this page used the 2.4 mg weight-management dose, and its figures describe that dose.
The US Ozempic label gives an elimination half-life of approximately one week and says semaglutide will be present in the circulation for about five weeks after the last dose (US Ozempic label). The US Ozempic label gives no instruction on tapering when stopping (US Ozempic label).
If Ozempic was prescribed for type 2 diabetes
This page is about the weight side of coming off. If Ozempic was prescribed for diabetes, any decision to stop, reduce or switch it belongs to the doctor managing the diabetes. GetLean is a weight-management programme and does not replace that doctor.
Already on Ozempic with another doctor
If you are already on Ozempic with another doctor, tell us which GLP-1 medication and dose you are currently taking when you complete the eligibility check, and bring any recent records to your consultation. Dr Quek confirms whether the programme is suitable for you at your consultation. Nothing is prescribed or dispensed before he has assessed you, and a consultation does not guarantee that a prescription will be issued. While that is arranged, do not stop or change Ozempic on your own; that is a conversation with the doctor who prescribed it.
What makes coming off go better
Building what replaces the medicine before the medicine goes: muscle protected with resistance training, an eating pattern that has stopped needing effort, and a habit of weighing that is already running before the last dose. In the withdrawal trials the medicine was stopped on a date, with no taper; a planned exit is built the other way round. While appetite is quiet, the daily WhatsApp coaching builds the eating pattern and the training habit. Designed to end: planning a GLP-1 exit sets out what the plan contains.
Exercise also counts after the medication stops. In a Copenhagen randomised trial that followed adults for a year after treatment ended, those who had combined a GLP-1 medication with supervised exercise were more likely than those who had taken the medication alone to still hold a loss of at least 10% of their starting weight (Jensen 2024). The medication was liraglutide, an earlier GLP-1 medicine, and the initial loss came from a low-calorie diet.
At GetLean, the programme is designed to end: our philosophy is that GLP-1 medication should act as a catalyst — not something to depend on indefinitely. The taper is planned from the first consultation and set at the monthly reviews as the response comes in.
Individual results vary, and clinical-trial figures describe the populations studied. Never stop or change a prescribed medicine on your own; that is a conversation with the doctor who prescribed it.
What happens after the taper at GetLean?
Finishing the taper does not have to end the support. After the taper, a patient can keep the daily WhatsApp coaching and the monthly reviews with Dr Quek by continuing the monthly subscription, if they wish. If the weight starts coming back, they can come back to Dr Quek at any time: a restart begins with a review consultation, and whether to restart the medication is his decision at that review.
Designed to end: a programme whose pace and taper off the medication are planned from the first consult, so the result holds after the medication stops.
Common questions
How long does Wegovy stay in your system after stopping?
Semaglutide's elimination half-life is about one week, and the US label says it is present in the circulation for about five to seven weeks after the last injectable dose (US label); the EU label says about seven weeks after the last 2.4 mg dose (EU SmPC). Both say to stop at least two months before a planned pregnancy.
How much weight comes back after stopping Wegovy?
In the STEP 1 extension, adults who had lost 17.3% over 68 weeks and then stopped both semaglutide and the lifestyle programme at once, with no taper, regained 11.6 percentage points by week 120, about two-thirds of the loss, finishing 5.6% below where they started (Wilding 2022). Individual results vary.
Do you need to taper Wegovy?
The labels give no taper instruction, and the withdrawal trials stopped treatment outright, with no taper. At GetLean the dose is stepped down at Dr Quek's monthly reviews rather than stopped overnight, so appetite can adjust step by step. Any change to a prescribed dose is a decision for the prescribing doctor.
Does the same apply to Ozempic?
Ozempic is the same molecule, semaglutide, at lower doses, and is registered in Singapore for type 2 diabetes only (NDF). The withdrawal trial described here used the 2.4 mg weight-management dose, so its figures describe that dose.
How long does Ozempic stay in your system after stopping?
Semaglutide's elimination half-life is about one week, and the US Ozempic label says it is present in the circulation for about five weeks after the last dose (US Ozempic label). The US label for the 2.4 mg weight-management product says about 5 to 7 weeks after the last 2.4 mg injection (US label).
I am on Ozempic with another doctor. Can GetLean help me plan coming off?
You are welcome to complete the eligibility check and tell us which GLP-1 medication and dose you are currently taking. Dr Quek confirms whether the programme is suitable for you at your consultation, and nothing is prescribed or dispensed before he has assessed you. If Ozempic was prescribed for type 2 diabetes, decisions about stopping or changing it belong to the doctor managing the diabetes.
What happens after the taper at GetLean?
A patient can keep the daily WhatsApp coaching and the monthly reviews with Dr Quek by continuing the monthly subscription, if they wish. If the weight starts coming back, they can come back to Dr Quek at any time; a restart begins with a review consultation, and whether to restart the medication is his decision.
