Missed 2 Weeks of Wegovy: How to Restart Safely

Why a two-week break changes the re-entry point

The Wegovy titration schedule exists for a reason rooted in tolerability, not arbitrary caution. Semaglutide slows gastric emptying and acts on GLP-1 receptors in ways that your body gradually adjusts to as the dose climbs. Jump back to 1.7mg or 2.4mg after a fortnight off, and that adaptation has partially unwound. The result, for many people, is a return of the nausea, vomiting and loose stools that were more pronounced at the start of treatment.

The NHS patient information for semaglutide advises that if more than five days have passed since a missed injection, that dose should be skipped and the next one taken on the usual day. A two-week gap is therefore not a case of being a few days off schedule; it is a meaningful break that the prescriber's team needs to hear about, and our dedicated guide to missing two weeks of Wegovy walks through exactly what that conversation with your prescriber should cover. Most clinical guidance for semaglutide suggests stepping back at least one dose level after a break of this length, though the exact step depends on how far through the titration schedule you were, how your body responded originally, and any changes in your health since you last injected.

If you store your pen in the fridge door and your usual injection day has come and gone twice without you touching it, that is the signal to contact your prescriber before the third week ticks past.

What 'stepping down' looks like in practice after missing two weeks

Stepping down does not mean going back to the very beginning. Someone who had reached the 2.4mg maintenance dose and then missed two weeks would typically be advised to restart one dose level lower (at 1.7mg) and retitrate from there rather than dropping all the way back to 0.25mg. Someone who had only just moved up to 1mg from 0.5mg might be guided back to 0.5mg. The principle is proportionate: the longer the gap and the higher the dose you left at, the more conservative the restart.

It is worth understanding what the doses actually represent. The titration rungs in the Wegovy schedule (0.25mg, 0.5mg, 1mg, 1.7mg, 2.4mg, and now up to 7.2mg with the MHRA's approval of the higher-dose pen in April 2026) are not arbitrary intervals. Each step is designed to let your gastrointestinal system settle before the next increase. The full Wegovy dose structure covers what each level is intended to do and how long titration typically takes. Re-entering the schedule thoughtfully protects that progress.

The Mounjaro SmPC (available on the eMC) contains equivalent stepping-back language for tirzepatide; the semaglutide SmPC follows the same logic. Both are published precisely so that patients and prescribers can make informed decisions when schedules are disrupted.

How a two-week gap affects weight and appetite, and what that means for your plan

Two weeks without semaglutide is long enough for plasma levels to fall noticeably. Semaglutide has a half-life of roughly a week, meaning that by the end of your second missed week, your circulating levels are significantly below the steady state you had built up. For most people, appetite begins to return before the two weeks are up. That is not a sign that the medicine had stopped working; it reflects normal pharmacokinetics.

Some people find that the return of appetite during a gap feels more intense than they expected, particularly if they had been on a maintenance dose long enough to feel genuinely comfortable around food. Understanding how Wegovy works in terms of appetite signalling can make that experience feel less alarming. Weight loss pauses during the gap, and a small amount of regain is possible, particularly if appetite drives higher calorie intake. This tends to resolve once a therapeutic dose is re-established.

The evidence base for semaglutide's effect on weight comes primarily from the STEP 1 trial, published in the New England Journal of Medicine, which reported an average reduction of around 15% body weight over 68 weeks at the 2.4mg dose alongside lifestyle changes. That result was built on consistent weekly dosing; gaps disrupt the steady-state concentration that underpins it. Getting back on schedule, with clinical guidance, is the practical priority.

Getting back on track: when to contact your prescriber

A two-week gap is the kind of thing prescribers hear about regularly. It happens during illness, holidays, supply issues, and periods when life overtakes routine. None of those are reasons to feel awkward about making contact. The practical question your prescriber will work through with you is straightforward: which dose to restart at, whether to stay at that level for a full four weeks before going back up, and whether anything in your health picture has changed during the break.

If you are thinking about the cost of continuing treatment alongside the disruption, understanding what Wegovy typically costs in the UK private market may be a useful background read. At nume, a named prescriber reviews every repeat order before anything is dispensed — there is no algorithm waving things through. That means a restart conversation can happen through the same channel as your ongoing care.

If your gap has now stretched closer to three weeks, the considerations shift slightly; the guidance for a three-week break covers that territory in more detail. And if you want a broader grounding in missed-dose rules across the schedule, the general Wegovy missed-dose page sets out the full picture.
