Injecting Wegovy on video: what most guides get wrong

The biggest myth: that the injection angle is the hard part

Most people searching for a video on injecting Wegovy expect technique to be the challenge. In practice, the pen does most of the work. The needle is short, hidden inside the cap, and retracts automatically once the injection is complete. What trips people up is usually not the angle but the pause, the full ten seconds after pressing the button, before lifting the pen away. Lift early and you risk not delivering the full dose.

The correct approach, as described in the NHS semaglutide patient information, is straightforward: choose your site, clean the area, remove the cap, press the pen flat against your skin, and hold the button firmly. You will hear a first click when the injection begins and a second click a few seconds later. Keep the pen still for ten seconds after that second click, then lift away. The needle cover slides back on its own.

If you want to watch this done in real time before your first injection, our step-by-step video guide for the Wegovy pen walks through each stage clearly. Watching once before you begin is genuinely useful, most people feel a lot calmer for it.

One misconception worth letting go gently: you do not need to aspirate (pull back on the plunger to check for blood) with a subcutaneous pen injection. That step belongs to a different era of injection technique. The Wegovy pen is designed specifically for subcutaneous use, and the leaflet does not include it.

Choosing and rotating your injection site

Three sites are suitable for Wegovy: the abdomen (at least a few centimetres from the navel), the front or outer thigh, and the outer upper arm. If you are injecting into your upper arm yourself, most people find the thigh or abdomen easier to reach cleanly. A carer or partner can use the upper arm more comfortably.

Rotation matters. Injecting the same small patch repeatedly causes the tissue to thicken over time, which slows absorption. The practical rule is to move at least a couple of centimetres from last week's spot, working around the available area before returning. Some people find it helpful to note where they injected last, a simple note on their phone, or a loose pattern like left abdomen one week, right thigh the next.

For a closer look at how site choice affects how the medicine works, the evidence on injection site differences is worth reading before you settle on a routine. Whether the abdomen produces faster absorption than the thigh has been studied, and the answer is nuanced. Your prescriber can advise based on your specific situation.

Alcohol swabs are commonly used to clean the skin beforehand; if you prefer to use them, sterile alcohol swabs are available through our pharmacy. The leaflet notes that swabbing is not strictly required if the skin is visibly clean, but many people prefer the routine of it.

Storing the pen and what to do if something goes wrong

Wegovy pens are refrigerated at 2–8 °C. Before injecting, allow the pen to sit at room temperature for a period specified in your Patient Information Leaflet, injecting cold medicine is more uncomfortable than it needs to be. The exact time window for room-temperature storage is stated in the leaflet rather than here, because it matters that you follow the figure specific to your product rather than a rounded approximation.

If your pen looks damaged, has been dropped, or the liquid appears cloudy or contains particles, do not use it. Our guide on what to do after dropping a Wegovy pen covers this specifically. The short version: inspect it carefully before every injection and contact your prescriber or our aftercare team if you are uncertain.

After use, the needle end should be disposed of in a sharps container rather than in general waste. A small sharps bin is practical for home use and keeps used pens safely contained between collections. Your local council or pharmacy can advise on sharps disposal collection in your area.

Semaglutide is also used in other branded medicines, if you have been researching Ozempic and how it compares to Wegovy, the injection process is similar, but the two medicines are licensed for different purposes and are not interchangeable. Ozempic is licensed for type 2 diabetes in the UK, not weight management.

Getting started: the clinical side before the practical one

Before technique becomes relevant, a prescriber has to decide whether Wegovy is appropriate for you. The licensed indication covers adults with a BMI of 30 or above, or 27 and above with a weight-related condition such as high blood pressure or type 2 diabetes. Lower BMI thresholds can apply for some ethnic backgrounds under UK guidance. A clinical assessment reviews your full picture (medical history, current medicines, and any contraindications) not just your BMI.

If cost is a consideration, the Wegovy cost breakdown explains what private treatment typically includes and why the headline price varies between providers.

Once you have a prescription and your pen is in hand, the technique really does come quickly. Most patients feel confident by their second or third injection. If questions come up between doses, our aftercare team is available seven days a week, you can reach us via our contact page.
