How to Come Off Wegovy: What Happens When You Stop

Does semaglutide need to be tapered, or can you just stop?

Unlike some medicines that require a gradual wind-down, there is no pharmacological reason to taper Wegovy before stopping. The NHS semaglutide medicines page does not describe a mandatory dose-reduction schedule before discontinuation. You can, in principle, simply stop after your last pen, but "can" and "should" are different questions.

The practical case for discussing the decision with your prescriber is strong. If you are stopping because of a side effect, they may be able to adjust your dose or approach. If you are stopping because treatment has run its course, they can help you plan what comes next. Stopping without a plan is the main reason people find weight regain harder to manage.

How you come off Wegovy matters less than what you put in place before the final dose lands. That is the conversation worth having. If you have not yet started treatment and are weighing up your options, our Wegovy overview sets out how the medicine works from the beginning.

How quickly does appetite return after stopping Wegovy?

Semaglutide has a half-life of roughly one week, which means meaningful concentrations remain in your system for several weeks after the last injection. Most people notice appetite beginning to increase within one to two weeks of stopping, with the full effect gone by around four to five weeks.

What catches people off guard is not just hunger returning, but its character. Wegovy dampens the brain signals that drive cravings and reward-eating, not just baseline hunger. When those signals come back, food can feel more compelling than it did before treatment, particularly in the first few weeks. How long Wegovy takes to wear off is covered in more detail on a dedicated page, because the timeline varies by dose and how long you have been using it.

Knowing this in advance lets you prepare. Having a structure for meals (even something as simple as eating at the same time each day) reduces the chance that the returning appetite catches you without a plan.

What does the evidence say about weight regain after stopping?

The STEP 1 extension study is the clearest data point available. Participants who stopped semaglutide 2.4mg after 68 weeks and received lifestyle support alone regained, on average, about two-thirds of the weight they had lost within one year of stopping, a finding published in the New England Journal of Medicine. NICE's appraisal of semaglutide acknowledges this trajectory, which is one reason NICE guidance (TA875) recommends Wegovy for a maximum of two years within a specialist service rather than as an open-ended prescription.

That figure can feel discouraging, but context helps. The participants who maintained the most weight were those who used the intervening period to build sustainable eating and movement habits, not those who relied on the medicine alone. Managing weight after Wegovy ends is a real, evidence-informed challenge, not an inevitability. Protein adequacy, adequate sleep, and consistent resistance training are the three factors the research points to most consistently.

For people thinking about what private treatment costs across its full course, our Wegovy price comparison sets out what UK providers typically charge and what those prices do and do not include.

Should you consider pausing rather than stopping entirely?

Some people come off Wegovy not because they want to stop permanently, but because of a planned pregnancy, a surgical procedure, a period of financial pressure, or simply a break. Pausing and restarting is clinically possible, though each restart requires fresh clinical assessment rather than picking up where you left off, your prescriber needs to review your current weight, health status and any changes since your last dose before continuing.

A question our prescribers hear fairly often is whether stopping for a few weeks to "reset" tolerance is worthwhile. The evidence does not support tolerance as a clinically meaningful issue with semaglutide; if the medicine has stopped feeling effective, the more likely explanations are adherence, dietary patterns, or the need for a dose review. Addressing a plateau while still on Wegovy is worth exploring before stopping entirely. Similarly, if your concern is about semaglutide specifically rather than injectable treatment as a whole, switching from semaglutide to a different treatment is a conversation your prescriber can walk you through. Whatever direction you are heading, a structured plan made with a clinician is the thing that makes the difference.
