Where to inject Wegovy in your leg — the right spot and how to find it

Step 1, Finding the right part of the thigh

Sit in a comfortable chair with your leg resting flat, slightly relaxed. Look at the outer face of your thigh, not the front face where the quadriceps muscle sits, and not the inner thigh, which has a richer network of blood vessels and nerves running close to the surface.

Picture the thigh divided into thirds from knee to hip. The middle third on the outer side is your target. In practice this means a hand's width above the knee and a hand's width below the hip, on the outside of the leg. If you run your hand along the outer seam of your trousers, the injection zone broadly follows that line in the middle section.

Avoid areas that feel hard or have visible lumps. If you have scarring from previous injections, move at least 1–2 cm away from it. That tissue absorbs medicine less reliably, and the same goes for bruised skin. You can find a fuller discussion of all approved injection sites in our guide to where to inject Wegovy, which covers the abdomen and upper arm alongside the thigh, and if you are considering the arm specifically, our page on where in the arm to inject Wegovy explains exactly which part to use.

Step 2, Preparing the site and the pen

Wash your hands thoroughly with soap and water first. Then, if you have them, wipe the skin with an alcohol swab and let it dry completely, injecting through wet skin can sting more and may affect the site. The pen itself should have come out of the fridge at least 30 minutes before you inject; a pen at room temperature is noticeably more comfortable than a cold one.

Your Wegovy pen arrives via tracked DPD delivery in plain, unmarked packaging. If it has been in transit, check the pen is clear and colourless before use and has not been frozen at any point. The Patient Information Leaflet inside the box covers storage details precisely, always follow the leaflet rather than relying on memory for temperature windows.

Remove the pen cap just before you inject. Do not prime the pen by firing a test shot, Wegovy pens are pre-set and single-use; pressing the button outside the skin wastes a dose. Check that the expiry date has not passed and that the liquid in the viewing window looks right.

Step 3, Injecting into the thigh correctly

Pinch around 5 cm of skin between your thumb and two fingers to lift a fold of subcutaneous tissue away from the muscle underneath. This is especially useful for leaner thighs where the fat layer is thinner. Position the pen at a 90-degree angle to the pinched skin, straight in, not at a slant. Place the pen firmly against the skin until the yellow safety cap retracts, then press and hold the button until you hear or feel the click and the yellow indicator confirms the dose is complete.

Hold the pen in place for about six seconds after the click before withdrawing it in one smooth motion. Release the pinched skin, then apply gentle pressure with a clean fingertip or cotton pad if there is any minor bleeding. Do not rub, rubbing can irritate the tissue. Dispose of the used pen in an approved sharps bin; used pens should never go into household recycling or general waste.

For a detailed walkthrough of the injection technique specifically for the leg, our step-by-step Wegovy leg injection guide covers grip, angle and common mistakes in more depth.

Rotating sites and common issues with the thigh

Rotation matters more than many people expect. Injecting in the same small spot week after week creates lipohypertrophy, fatty lumps under the skin that feel firm and absorb semaglutide unpredictably. This can make your doses less effective without any obvious reason. A simple rotation pattern might be: left thigh one week, abdomen the next, right thigh the week after, then the upper arm, and so on.

The most common local reactions at the thigh site are mild redness, a small raised weal or bruising, all of which normally fade within a couple of days. If you notice persistent swelling, hardening, or skin changes at a previous injection site, mention it to your prescriber before the next dose. A question our prescribers hear regularly is whether using the Wegovy injection leg site or the abdomen produces better results, the evidence does not firmly favour one over the other for semaglutide absorption, so personal preference and ease of access are reasonable guides. People who find the abdomen uncomfortable after meals, for instance, often prefer the thigh.

Skin and injection-site symptoms are among the reactions you can report through the MHRA Yellow Card scheme, alongside any other suspected side effects. It exists for a reason and is worth knowing about. If you are newer to weight-loss injections and want broader context, our guide covering where to inject semaglutide explains the approved sites and how to choose between them. For questions about the cost of private Wegovy treatment, the Wegovy price comparison page sets out what legitimate pricing in the UK typically involves.

If anything about your injection site concerns you, or you are not sure your technique is right, the team at nume's support line is available seven days a week, and our clinical team reviews every patient's case before each repeat prescription, so there are natural moments to raise questions.
