What Happens If You Miss a Dose of Wegovy

The decision you actually face when a dose is late

A missed Wegovy injection rarely happens at a convenient moment. You remember on a Tuesday that Friday was injection day, or you find the pen at the back of the fridge on a weekend morning and realise you lost track of the days. The good news is that the decision tree is short.

Count the days between now and your next scheduled injection. Five days or more still to go? Inject the missed dose today, then continue as normal on your usual day the following week. Fewer than five days until the next dose? Leave the missed one out and simply carry on to the next planned injection. Your dose level does not change either way, there is no need to step back to a lower strength because of a single skipped week.

This is different from intentionally pausing Wegovy for a week, which raises its own questions worth reading about separately. A forgotten dose and a planned break are not the same situation, and they are handled differently.

The one thing that matters most: do not inject twice in close succession to make up for the gap. Taking two doses within a short window does not accelerate weight loss and significantly increases the chance of nausea, vomiting and other gastrointestinal discomfort. If you are unsure about the timing, the NHS semaglutide guidance and your Patient Information Leaflet are both clear on this point.

What a missed dose does (and does not) do to your progress

Semaglutide works by staying in your system over time. Each weekly injection maintains a steady level of the medicine in your body, which is why once-weekly dosing is effective for most people. A single missed injection does not wipe that out. Levels fall gradually, so the appetite-reducing effect softens rather than disappears overnight.

You may notice your appetite returning a little more than usual in the days before your next injection. Some people find they feel hungrier or that meals feel less filling. That is a normal response to slightly lower levels of the medicine and tends to resolve once the weekly rhythm resumes.

What a missed dose does not do is reset your position on the titration ladder. Wegovy is started at 0.25mg and increased by the prescriber through a series of steps, you can read more about the full Wegovy dose schedule and what each stage involves. A forgotten injection does not send you back to the beginning of that schedule, and if you are curious about what happens when someone begins Wegovy at 1mg rather than the standard starting point, that is a separate question with its own considerations. Your next dose is the one your prescriber already set.

If you are ever tempted to take a higher dose to compensate, it is worth reading about what happens when a higher Wegovy dose is taken outside the prescribed plan, the short answer is that it introduces risk without clinical benefit.

When a pattern of missed doses needs a proper conversation

One forgotten injection is not a crisis. A recurring pattern is different. If you find yourself regularly missing doses (perhaps because the injection day clashes with a busy weekly routine, or because side effects make you reluctant to take the next pen) that is information worth sharing with your prescriber rather than managing quietly on your own.

The cost of Wegovy is a real consideration for many people, and missing doses while still paying for treatment each month is frustrating. A frank conversation about whether the timing, the dose, or the treatment itself still fits your situation is a reasonable thing to request. You can see a breakdown of what private Wegovy treatment typically involves on the Wegovy cost page.

There are also practical reasons doses get missed that are easy to solve. Keeping the pen somewhere you will actually see it (on the fridge shelf at eye level rather than tucked behind other things) makes a genuine difference. Some people tie their injection day to something fixed in the week, like Sunday evening before the working week begins, so it does not drift.

If side effects are the reason you are hesitant, that conversation matters most of all. Nausea and gastrointestinal discomfort are common during dose increases and can be managed; an experienced prescriber can slow the titration pace or offer practical tips before you consider stopping. Our Wegovy treatment overview covers the side-effect profile honestly, and our clinical team reviews every case individually. If you have questions about your current treatment or are thinking about starting, checking your eligibility is the right first step.
