Missed a Wegovy Shot? Here's What to Do Next

The decision the five-day rule is actually asking you to make

When you realise you have missed your Wegovy shot, there is one question that resolves almost everything: how many days until your next scheduled dose? Count them carefully, then apply the guidance in the NHS patient information for semaglutide. Five or more days left means you can inject the missed dose straight away and then return to your normal weekly day. Fewer than five days left means the sensible move is to leave that dose out entirely and resume on schedule.

The logic behind this is straightforward. Wegovy stays active in the body for several days after each injection, which is why it works as a once-weekly medicine. Taking a dose when the next one is very close creates an unintended overlap, raising the concentration of semaglutide in your system above what the titration schedule was designed to produce. That increases the likelihood of nausea, vomiting or other gastrointestinal effects without offering any extra benefit.

One missed dose, handled correctly, is not a clinical event worth worrying about, and if you are wondering whether it is ok to miss a week of Wegovy altogether, the short answer is that occasional gaps are unlikely to derail your progress when managed properly. What matters is that you do not try to compensate by injecting more than once in a single week. If you are regularly forgetting doses, it is worth talking to your prescriber about whether there is a better day of the week that fits your routine, that conversation costs nothing and can make a real difference to consistency.

What to do if you have missed two weeks or more

A single late dose is one thing. A gap of two weeks or longer is a different situation, and it is one where you genuinely need clinical input before injecting again. After a prolonged break, your body's tolerance to semaglutide will have dropped, and picking up from where you left off at a higher dose can cause stronger-than-expected side effects. Your prescriber may advise restarting at a lower dose and re-titrating upward, in the same way a new patient would.

There is a fuller discussion of the considerations involved in what happens if you miss two weeks of Wegovy, including when re-titration is likely and what to tell your prescriber. The short version: do not self-decide to stay on your current dose after a long gap. Contact the team who prescribed for you first.

If you sourced your Wegovy through nume, our aftercare team is available seven days a week. A quick message is all it takes. Our prescribers can review the situation and advise whether to step back down a dose or continue as planned, and that advice is included as part of the service, with no additional charge.

Injection technique and storage after an unplanned delay

Before you inject the missed dose, it is worth confirming that the pen has been stored correctly throughout the gap. Wegovy pens must be kept refrigerated between 2°C and 8°C; the exact room-temperature window during which the pen remains usable is set out in the Patient Information Leaflet, and that is the definitive source, not an online forum and not a rough estimate from memory. If you are at all unsure whether a pen has been compromised by heat or improper storage, do not use it. Contact the pharmacy.

On the injection itself: if you could use a refresher on technique, there is a practical walkthrough of how to give a Wegovy shot that covers site rotation, the subcutaneous angle and what to do if the pen does not click. Rotating between the abdomen, thigh and upper arm matters more than most people realise, the same spot repeatedly can affect how consistently the medicine is absorbed.

When your next pen arrives from us (plain packaging, tracked through DPD, no clue on the outside what's inside) pop it straight into the fridge. That habit alone removes one category of problem. If you have questions about the injection process or are reconsidering whether Wegovy is the right approach for you, the Wegovy overview covers how it works, what the evidence says and how to get started properly through a licensed route.

When a missed dose is a sign to revisit your treatment plan

If missed doses are becoming a pattern, that is worth raising with a prescriber rather than quietly managing alone. Sometimes side effects are making injections feel unappealing. Sometimes life circumstances have changed and weekly injections no longer fit. Sometimes the current dose is not producing enough benefit to feel motivated.

All of these are legitimate clinical conversations, not admissions of failure. The MHRA-approved titration schedule for Wegovy exists precisely because tolerance and response vary between people, and your prescriber can adjust accordingly. If you want a clear picture of what happens if you miss a week of Wegovy, including how your body responds and what steps to take next, that page sets it out in full. If injection frequency itself is the barrier, it may be worth exploring what other treatment options are available, including the oral semaglutide now approved in the UK, which removes the injection question entirely for those who prefer a tablet.

The semaglutide page covers both the injection and tablet forms in one place, with the clinical differences laid out factually. And if you are not yet on treatment but are weighing up whether Wegovy is right for you, the weight loss treatment overview is a reasonable starting point before you speak to a prescriber.
