Missing a Week of Wegovy: What Happens and How to Get Back on Track

Step 1, Work out exactly how many days have passed

Before doing anything else, count carefully. Wegovy is a once-weekly injection, so your usual pattern has a specific day attached to it. The official guidance, set out in the approved Patient Information Leaflet and summarised on the NHS's semaglutide medicines page, hinges on a five-day window. If you are within five days of your missed injection (say you normally inject on a Monday and it is now Thursday) you can take the dose as soon as you remember, then return to Monday the following week as usual.

If more than five days have passed, the guidance changes. In that case, leave the missed dose entirely and continue with your next scheduled injection on the usual day. That might feel counterintuitive, but it is the safer path. Taking a dose too close to the next planned one compresses the gap and makes side effects more likely.

Write down the date as soon as you realise what has happened. It sounds obvious, but several days of uncertainty can blur together, and an accurate count genuinely changes what you should do. If you are unsure about the timing, contacting your prescriber before injecting is always the right move.

Step 2, Decide whether you need to restart at a lower dose

A single missed week is unlikely to require a dose step-down. Your body has not lost all adaptation to semaglutide in seven days, and most people can resume at their current dose without a significant increase in side effects.

The situation changes if you have missed wegovy for a week or more repeatedly, or if supply issues have left you without your pen for two or more weeks. In those cases, your prescriber may suggest dropping back by one dose level to let your system readjust before stepping up again. That is a clinical judgement, not a rule you can apply yourself from a list.

You might be feeling frustrated right now, especially if your missed dose was not your fault, a pen out of stock, a delivery that did not arrive in time, or simply a chaotic week. That frustration is understandable. The good news is that semaglutide's relatively long half-life means your body does not switch off completely between doses, and a brief gap rarely undoes the metabolic changes that have built up over weeks of treatment.

Step 3, Manage what you might notice in the gap

As the level of semaglutide in your system falls during a missed week, some things may shift noticeably. Appetite often returns faster than people expect. Many patients find that hunger feels sharper than it did in the weeks before, and foods that had lost their pull might feel appealing again. This is not a sign of treatment failure; it reflects the medicine's mechanism wearing thinner.

Gastric emptying may also speed back up slightly, which for some people means digestion feels different. If you had found a comfortable eating rhythm on Wegovy, maintaining it consciously during the gap can help, particularly keeping portions steady and protein intake adequate.

One practical detail worth knowing: if you are missing a dose because of storage issues rather than forgetfulness, the Wegovy SmPC on the electronic Medicines Compendium sets out the exact conditions under which a pen can be kept at room temperature and for how long. Checking that before assuming a pen is unusable can save an unnecessary gap in treatment. Any pen that has been stored outside the permitted conditions should not be used.

Step 4, Know when to contact your prescriber before resuming

Most single missed doses can be handled by following the Patient Information Leaflet guidance, but some situations do warrant a conversation with your prescriber first. Contact them before your next injection if: you have been without Wegovy for more than two consecutive weeks; you have had significant side effects since your last dose and are unsure whether they are connected; your circumstances have changed in a way that might affect your suitability for treatment; or you are simply not confident about which dose to take next. If you are asking yourself whether it is ok to miss a week of Wegovy, our guidance page walks through the key considerations, and if you want a slightly different framing, we also cover whether it is okay to miss a week of Wegovy in a separate resource. For a direct answer to the question of whether you can miss a week of Wegovy, that page sets out what the evidence and prescribing guidance actually say.

At nume, every prescription is reviewed by a named GPhC-registered prescriber before it is issued, and clinical support is available seven days a week. If you are a patient with questions about restarting after a gap, reaching out through our aftercare contact is faster than waiting until your next repeat order.
