Wegovy injection locations: choosing where to inject each week

The three sites and what makes each one different

The abdomen, the thigh, and the upper arm are all clinically accepted Wegovy shot locations. Each has practical advantages worth knowing before you settle into a routine.

The abdomen is the most popular starting point for people who self-inject. There is generally more subcutaneous tissue here, the area is easy to pinch and reach, and many people find it the least uncomfortable site. Aim for the fatty tissue around the navel, but avoid a two-inch radius directly around it. The lower abdomen tends to be more comfortable than the sides for most people.

The front or outer thigh is a strong alternative, particularly if the abdomen is sore or if you have recently had abdominal surgery. You can see clearly what you are doing, and stabilising the injection with one hand is straightforward when sitting down.

The upper arm (specifically the outer, fatty part) is an option when a partner, nurse, or carer is giving the injection. Self-injecting into the upper arm is technically possible but awkward, and many people find it harder to control the angle correctly. If you are managing entirely alone, starting with the abdomen or thigh makes practical sense. You can read more about which site tends to produce the most consistent results on our page about the most effective Wegovy shot location.

One detail the NHS patient guidance on semaglutide is clear about: you can use the same region week after week, but you should move the exact spot within that region every time.

Why rotation is the decision that protects absorption over time

Injecting repeatedly into the same small patch of skin causes cumulative tissue changes. The medical term is lipodystrophy, areas of hardened, lumpy, or indented tissue that develop when subcutaneous fat is repeatedly disturbed. This matters beyond cosmetics: injecting into affected tissue can reduce how reliably your body absorbs semaglutide, which in turn affects how well the treatment works.

A sensible rotation pattern covers both sites and moves a few centimetres with each injection. Some people divide the abdomen into a clockwise grid of positions and work around it methodically. Others alternate between the abdomen and thigh week by week. Either approach works provided you are genuinely moving the needle placement rather than clustering in a favourite spot.

If you notice a lump, a persistent bruise, or a firm patch developing at a site you use often, let your prescriber know. It may simply mean resting that area for a few weeks, but it is worth flagging rather than injecting through it. For a broader picture of how the medicine can affect you, the complications of Wegovy page covers the side-effect profile in more detail.

This is also the kind of practical question our clinical team fields regularly, and it is exactly the sort of thing worth raising at your first review rather than trying to troubleshoot alone several months in.

Timing, habit, and making the weekly injection sustainable

Wegovy is injected on the same day every week, but that day is yours to choose. Picking a day that fits your real life matters more than which day it is. Payday Friday, a calm Sunday evening, or a Monday when the week feels fresh, whatever you will actually remember without a reminder app is the right choice.

Temperature affects your pen before you inject. Wegovy should be stored in the fridge between 2°C and 8°C. If the pen has been refrigerated, some people find letting it sit at room temperature for around 15 to 30 minutes before injecting reduces discomfort at the site, but for the precise storage window and conditions, the Patient Information Leaflet with your pen is the authority, not general advice online. If you are travelling, that storage window changes; again, the leaflet has the figures.

The technique itself (speed of insertion, angle, whether to pinch the skin) is covered step by step in the leaflet and should be demonstrated or confirmed by your prescriber if you have any doubts. Rushing the injection or choosing a site out of convenience when a better one is available are the most common causes of site discomfort in the first few weeks. Both are easy to fix once you know what to look for. If you are thinking about starting treatment, who semaglutide is indicated for is a practical starting point before you reach the consultation stage.

Getting the prescription right before technique matters at all

None of the above applies until you have a valid prescription from a clinician who has assessed whether Wegovy is suitable for you. Wegovy is licensed in the UK for adults with a BMI of 30 or above, or 27 or above alongside at least one weight-related health condition, but eligibility is assessed individually, not on BMI figures alone. If you are still trying to find somewhere to obtain it, our Wegovy locator can help you identify where the treatment is available before you reach the consultation stage. The Wegovy overview page covers the licence and what the clinical assessment involves.

If you are weighing up costs alongside clinical fit, the Wegovy cost page sets out the honest picture of what private treatment involves (prescription, clinical oversight, and aftercare) so you are not comparing like with unlike. At nume, a prescriber personally reviews every consultation the same day; there are no algorithms making clinical decisions. The weight loss treatment overview explains how the process works if you want the broader context before you apply.

NICE's published guidance on semaglutide (TA875) and the NHS patient information on semaglutide set out the clinical framework your prescriber is working within. For anything specific to your situation (including whether a particular injection site is appropriate given your health history) your prescriber is the right person to ask.
