How Many Days Between Wegovy Shots?

Why is the interval exactly seven days?

Semaglutide has a long half-life (roughly one week in the body) which is precisely why a once-weekly injection works as a dosing model. Giving it every seven days keeps blood levels relatively stable rather than spiking and then dropping sharply. That steady-state profile is what the STEP clinical programme was built around, and it is the basis on which NICE recommended semaglutide for weight management in adults meeting the eligibility criteria. Spacing shots wider than seven days lets levels drift lower; spacing them closer risks stacking doses before the previous one has cleared.

Practically, most people pick the same day each week and stick to it. Monday suits some because it anchors the routine to the working week; others tie it to a prescription delivery or payday so the pen and the occasion line up. Any day works, what matters is consistency, not which day you choose.

If you are new to the injections and want a walkthrough of the process itself, how to take Wegovy shots covers site selection, technique and everything else that goes with the first few pens.

What if you go more than seven days between shots?

Life happens. A dose taken a day late (so eight days after the last one) is not a crisis. The licensed guidance allows you to take a missed dose up to five days late, provided there will still be at least four days before the next scheduled injection. If more than five days have passed since your missed shot, skip it and resume on your usual day. Do not inject twice in quick succession to compensate; that adds unnecessary side-effect risk without clinical benefit.

The full detail on how many days late you can take Wegovy sets this out clearly, including the four-day minimum gap rule. And if you have already missed a shot and are unsure what to do next, the guidance on how many days you can miss Wegovy covers the longer-gap scenarios, when to carry on, when to call your prescriber.

One point worth knowing: if you have held a dose for long enough that your body has effectively lost its tolerance to the current strength, your prescriber may recommend stepping back a dose before re-titrating. That is a clinical call, not something to manage alone.

Can you take shots closer together than seven days?

No. Taking two doses within fewer than four days is outside the licensed schedule and increases the risk of gastrointestinal side effects, nausea, vomiting, and stomach discomfort are the most common ones, and they are strongly dose-related. The schedule exists partly to give your system time to adjust between doses, especially during the titration phase when the prescriber is moving through the starting strengths toward the maintenance dose.

This question comes up most often when someone is trying to shift their injection day, for example, switching from Tuesday to Friday before a holiday. The safest approach is to move the day gradually, shifting by one or two days per week, rather than jumping across. Your prescriber can advise on the cleanest way to do it for your specific dose and history.

For a broader picture of how the weekly schedule fits into the overall treatment, Wegovy shots covers what to expect across the full titration journey. Those interested in how Wegovy compares with other options or who are considering starting treatment can also read about semaglutide more broadly.

Does the seven-day rule change at different dose strengths?

No, the interval stays the same throughout. Whether you are on the 0.25 mg starting dose or the 2.4 mg maintenance dose, one injection per week is the schedule. What does change is how your body responds to each increase, which is why the titration steps are spread roughly four weeks apart. That four-week minimum at each dose is about tolerability and effect, not about the weekly rhythm itself.

The NICE appraisal of semaglutide for weight management (TA875) sets out the clinical criteria under which the medicine is recommended, and it is the framework most prescribers reference when reviewing ongoing treatment. If your dose review is coming up and you want to understand where the NHS draws the line on continuing treatment, Wegovy tier 3 access explains the specialist pathway in plain terms.

Wegovy is a prescription-only medicine. A prescriber decides whether it is right for you, at what dose, and when to adjust.
