Skipping a Week of Wegovy: What to Expect and What to Do Next

Step 1: work out where you are in the five-day window

Semaglutide stays active in your system well beyond seven days, which is exactly why the once-weekly schedule works. When you miss an injection, the medicine does not vanish overnight. The practical threshold is five days: count forward from the day and time the injection was due. If you are still within that window, give the dose as soon as you remember, then return to your original weekly day going forward. If more than five days have passed, leave that week's dose entirely and pick up on your normal day the following week. Do not double up to compensate. That is not caution being overcautious — injecting two doses close together increases the risk of nausea, vomiting and other gastrointestinal effects without any meaningful benefit to weight loss. For a fuller look at the specific rules around a missed Wegovy dose, including examples for different day combinations, we have covered the detail elsewhere.

Step 2: understand what your body does during the gap

A question our prescribers hear most weeks is whether skipping a week of Wegovy will cause a rebound in hunger, and we explore that question in full, including what to expect from your appetite and energy levels during the gap. The honest answer: possibly, and temporarily. Semaglutide reduces appetite partly by slowing gastric emptying and partly through its action on hunger-signalling centres in the brain. As levels in your blood gradually fall across the missed week, those effects soften. Most people notice their appetite beginning to return, sometimes accompanied by a resurgence of food noise, in the latter days of the gap. Nausea, if you had it, often eases during the break too. None of this means the medicine has stopped working for you; it means the pharmacology is doing what it is supposed to do when the dose is not topped up. When you give the next injection on schedule, the cycle restores. The licensed dose schedule for Wegovy is designed around exactly this weekly rhythm, so one interruption sits within the range the trials accounted for.

Step 3: restart on your normal day and monitor how you feel

Give your next injection on the same weekday you always use, not a different day, not earlier to make up time. Consistency in timing matters for keeping blood levels stable. After skipping wegovy for a week, some people find the first injection back brings gastrointestinal side effects more noticeably than usual: nausea, loose stools or indigestion that had settled since the earlier weeks of treatment. This is not unusual. Go steadily with meals, keep portions moderate, stay hydrated, and give the medicine a few days to restabilise. If you are on a lower dose mid-titration and the symptoms feel significant, speak to your prescriber before your next planned dose increase rather than pushing ahead. If you are thinking about whether a planned holiday or surgery explains your gap, our guide to skipping Wegovy around a holiday covers practical timing considerations for trips abroad. For a broader look at weight-loss treatment options, including how Wegovy sits alongside other licensed medicines, our treatment overview is a useful reference. Costs and what to budget for are explained on our Wegovy cost page, if that is on your mind before a repeat order.

Step 4: know when to call your prescriber rather than managing alone

Most single missed weeks can be handled by following the five-day rule above, with no prescriber contact needed. But some situations do warrant a conversation. If you have missed more than two consecutive weeks, particularly at a higher maintenance dose, your prescriber may advise restarting at a lower dose to let your body readjust, pushing straight back to 1.7mg or 2.4mg after a longer gap raises the likelihood of side effects that could make continuing harder. If you experience severe or persistent stomach pain during or after a gap, seek medical attention promptly; the MHRA Drug Safety Update issued in January 2026 highlighted acute pancreatitis as an infrequent but serious known risk with GLP-1 medicines, with severe abdominal pain that may spread to the back as the key warning sign. And if missing doses is becoming a pattern rather than a one-off (because supply is disrupted, because life has been difficult, or because you are unsure the treatment is still right for you) that is precisely what aftercare is for. Speak to a prescriber rather than quietly stopping. At nume, every repeat order is reviewed by a GPhC-registered prescriber before it is approved, so there is a natural checkpoint built into each cycle. If any of this has prompted questions about whether you are still on the right plan, checking your eligibility takes a few minutes and costs nothing.
