How Long Can You Take Wegovy, and What Happens When You Stop?

What the NICE guidance actually says about duration

The honest starting point is the official NHS framework. NICE's appraisal of semaglutide (TA875) recommends Wegovy for a maximum of two years when used within a specialist weight management service, alongside dietary support and increased physical activity. That two-year boundary was set partly on economic grounds and partly because the long-term trial data at the time extended to roughly that window.

The guidance also includes a stopping rule: if you have not lost at least 5% of your starting weight after six months on the highest dose you can tolerate, continuing is unlikely to benefit you and should be reviewed. That threshold applies within the NHS. Private prescribers apply similar clinical reasoning, it is not arbitrary, it reflects what the trial evidence shows about who responds.

It is worth knowing that NICE's two-year cap applies specifically to NHS commissioning through specialist services. A private prescriber is not automatically bound by that ceiling, but they are bound by the medicine's licence, their clinical judgement, and their professional duty to reassess regularly. Longer private treatment is possible; it is not a rubber stamp.

How long to take Wegovy if you are on a private prescription

If you are wondering how long you can take Wegovy outside the NHS, the practical answer is: for as long as the clinical case for it holds, reviewed at every repeat. Private treatment does not come with a countdown, but it does come with accountability.

At nume (sorry, at a service like ours) every repeat order is clinically re-reviewed. That means a prescriber looks at your progress, your tolerance of the medicine and whether continuing makes sense before anything is dispensed. Treatment is never just auto-renewed. If you are curious about how that works day to day, our clinical model sets it out plainly.

The question of how long to take Wegovy is also bound up with your goals. Some people reach a stable weight that they can maintain through changed habits; for them, stopping becomes a planned clinical step. Others need longer support. Neither is unusual. What matters is that the decision is made with a prescriber who knows your history, not guessed at independently.

Weight regain after stopping, the honest picture

This is the part most people feel uneasy about, and it deserves a straight answer. Clinical trial evidence, including the STEP extension studies, shows that on average people regain much of the weight lost within one to two years of stopping semaglutide, without sustained lifestyle changes in place.

That is not a flaw in the medicine, it reflects the biology of obesity. Weight is regulated by hormonal and neurological systems that push back when energy stores fall. Semaglutide modulates those systems while you take it. When the medicine stops, those systems reassert. The NHS's obesity overview explains this biology clearly and is worth reading if you find yourself frustrated by that pattern.

The practical implication: the period before stopping matters as much as the treatment itself. A prescriber who knows you can help build a plan (around food habits, activity, and realistic expectations) that improves the chances of holding onto what you have gained. Some people find that dietary approaches during treatment also shape their outcomes after it ends.

None of this is a reason not to start. It is a reason to start with eyes open, and with a clinical team that plans for what comes next.

Deciding whether to continue, pause or stop

If you are currently on semaglutide and weighing up whether to carry on, the key factors your prescriber will consider are: how much weight you have lost and whether it has stabilised, how well you are tolerating the medicine, how long you have been on treatment, and what your plan looks like if you do stop.

You can find a useful summary of what NICE recommends (and what it means for NHS versus private access) on our Wegovy overview page. For context on what treatment typically costs privately, the Wegovy pricing page is worth a read before you make any decisions.

There are also related questions that come up alongside duration, for instance, how long it takes for Wegovy to work in the first place, or whether the semaglutide duration question changes if your prescriber switches the form of the medicine. These are good things to raise directly, our prescribers hear them regularly.

If you want a clinical view on your specific situation, checking your eligibility starts that conversation.
