Can you skip a week of Wegovy — and what actually happens if you do?

You had a busy week, forgot the injection, and now you're not sure what to do

It happens. Wegovy is a once-weekly injection, which most people find straightforward to build into a routine, but life gets in the way. A holiday, a stressful week at work, a pen that ran out unexpectedly, missing a dose is genuinely common, and the first thing to know is that one skipped week rarely derails a course of treatment.

The practical rule, drawn directly from NHS guidance on semaglutide: if you remember within five days of your missed injection day, take the dose straight away and then continue on your usual day. If it is already day six or seven (so your next scheduled dose is one or two days away) leave the missed dose entirely and simply take the next one as planned. Your weekly schedule does not change. You might feel that a week of reduced appetite suppression is frustrating, but trying to double up creates a far larger problem: a significantly higher likelihood of nausea, vomiting and stomach pain, with no clinical benefit to justify it.

For more detail on the single-dose scenario, the Wegovy skipped-dose guide goes through the five-day window in full, including what counts as the clock starting. Worth a read if you are unsure which side of the line you fall on.

What skipping a week of Wegovy can do to how you feel when you restart

Semaglutide works by suppressing appetite progressively as it accumulates to a steady tissue level. A single missed week will not erase that, the medicine's half-life is around one week, so levels fall but do not vanish overnight. Most people find their appetite creeps back slightly during the gap and settles again within a few days of resuming.

The more noticeable effect is on side effects. If you recently moved up a dose, your body had begun adjusting. A week's gap can partially reset that adjustment, meaning nausea and digestive discomfort may return when you resume, sometimes as strongly as when you first started that dose. This is not dangerous, but it is uncomfortable, and it catches people off guard. Staying hydrated, eating smaller and blander meals in the first few days back, and giving yourself a little extra time are the practical responses.

One week away from the injection is unlikely to affect your long-term results, particularly if your diet and activity habits have become established. The bigger concern with skipping Wegovy is what it signals about the routine: one missed week is nothing; a pattern of missed weeks is worth discussing openly with your prescriber, because there may be a dose or schedule adjustment that helps.

If you are weighing up a deliberate break for a holiday, there is specific guidance on skipping Wegovy during a holiday that covers the storage and timing questions that trip people up when travelling abroad.

When a skipped week becomes something your prescriber needs to know about

A single missed injection is a patient-managed event. Longer gaps are clinical ones. NHS guidance and the semaglutide Summary of Product Characteristics are aligned on this: if your treatment is interrupted for four weeks or more, resuming at your current dose carries a meaningful risk of significant side effects, and your prescriber may advise restarting at a lower dose and retitrating upward.

This matters most for people on the higher end of the Wegovy schedule. Someone on the 1.7mg or 2.4mg maintenance dose who misses a month is not in the same position as someone who misses a week at 0.5mg. The higher the dose, the more important it is to seek clinical guidance before resuming rather than simply carrying on.

Supply issues have occasionally forced gaps on people who did not choose them. If you are in that situation, the full breakdown of what happens when you skip a week of Wegovy is a useful reference, but it is not a substitute for prescriber advice on whether to retitrate. At nume, at our pharmacy, a GPhC-registered Independent Prescriber personally reviews every repeat order before it is dispensed; questions about resuming after a gap are exactly the kind of thing that review is there to catch.

The cost of treatment is a separate, practical question for many people, and understanding what is included in a private prescription is worth reading about on the Wegovy cost and pricing page if supply gaps have you rethinking your options.

The short answer, restated plainly

Can you skip a week of Wegovy? You can, and it will not wreck your progress, though our guide to skipping one week of Wegovy explains in more detail what to expect and how to handle the restart. Whether you should, and what to do when you resume, depends on how long the gap is, which dose you are on, and why the week was missed. Within five days: take it and continue. Beyond five days: skip it and keep your usual schedule. Beyond four weeks: talk to your prescriber before injecting again.

These are the verified parameters from the Wegovy SmPC on the eMC, and they are the same guidance our prescribers follow. If you are unsure which scenario applies to you, or if this keeps happening and you want to think through your treatment more broadly, starting a free consultation with our clinical team is the straightforward next step.
