How long can you stay on Wegovy for weight loss?

You've been on Wegovy for six months — now what?

Picture this: six months in, you've moved through the dose titration, the early nausea has eased, and the scale is moving in the right direction. The question that comes next is almost universal. A question our prescribers hear most weeks is some version of: "Do I have to stop soon?" The short answer is no, not automatically — but the longer answer depends on the pathway you're on.

If your Wegovy was prescribed through an NHS specialist weight management service, NICE's appraisal of semaglutide (TA875) sets a two-year maximum. That cap exists because the NHS recommends ongoing review against the clinical benefit seen, and because specialist service slots need to be shared. The guidance also says treatment should be reviewed if you haven't lost at least 5% of your starting weight after six months at the maintenance dose, not because time is up, but because non-response is a signal the medicine may not be working for you specifically.

Private prescribing is framed differently. The licensed indication for Wegovy doesn't carry a built-in two-year ceiling; the SmPC specifies use alongside a reduced-calorie diet and increased physical activity in adults with a qualifying BMI, and continuation is a clinical decision based on ongoing benefit and tolerability. That means your prescriber reviews your progress and health at each repeat, rather than counting down to a fixed end date. Responsibility for that ongoing assessment is real, it should not be a rubber stamp.

Why the two-year NHS limit exists, and what happens at that point

Weight regain after stopping semaglutide is well-documented. In the STEP 1 extension analysis, participants who discontinued after 68 weeks regained around two-thirds of their lost weight within a year. That finding matters for how you read the two-year NHS guideline: it isn't a cure horizon, it's a resource and review structure.

When someone reaches the end of their NHS course, the clinical team will assess what comes next, whether that's a referral for further support, a transition to a different pathway, or an honest conversation about maintenance strategies. How long you can stay on Wegovy through any route should be a genuinely individualised discussion, not a default decision made for administrative convenience.

On the private side, without the two-year ceiling, some people remain on treatment for considerably longer if the clinical benefit is sustained and tolerability is good. If you want to understand how long you should be on Wegovy for weight loss, the honest answer is that it depends on your individual clinical picture rather than a single fixed rule. NHS England's guidance on weight-management injections reinforces that lifestyle support runs alongside the medicine throughout, that combination matters for what happens after, whenever after arrives.

What if Wegovy stops working as well after a year or more?

Plateau is common and worth addressing directly. Some people find that weight loss slows significantly after the first six to twelve months, even at the 2.4mg maintenance dose. This can be a normal biological adaptation rather than a sign the medicine has stopped working entirely, but it's worth investigating. The MHRA approved the 7.2mg Wegovy pen in April 2026, giving prescribers a higher ceiling to work with for patients who tolerate lower doses well but whose progress has stalled.

If you're on an existing dose and progress has stopped, the right move is a conversation with your prescriber rather than a search for answers online. When Wegovy stops working as expected is something our clinical team reviews carefully, looking at dose, adherence, diet, activity, and whether another option might serve you better. Many patients also want to know how long they can use Wegovy for weight loss, and that question is best answered by a clinician who knows your history, not in isolation.

Switching from Wegovy to Mounjaro (tirzepatide) is something some patients and prescribers consider when semaglutide's effect plateaus; in the SURMOUNT-5 trial, tirzepatide produced greater average weight reduction than semaglutide 2.4mg over 72 weeks. That's a clinical conversation, not a consumer choice, and it's one our prescribers can have with you properly. If you'd like to check your eligibility for treatment, a free consultation is the right starting point.
