How to Administer Wegovy: Video Walkthrough and Injection Technique

What should a Wegovy administration video actually cover?

Not all injection videos are equal. A reliable one (from Novo Nordisk, your pharmacy, or the NHS) will walk you through the full sequence, not just the moment the needle goes in. Here is what to look for before you press play.

The video should begin with preparation: checking the expiry date, confirming the liquid is clear and colourless, and letting the pen reach room temperature (typically around 30 minutes out of the fridge). Cold semaglutide can cause extra stinging at the injection site, a simple thing to avoid, but easy to miss if you skip this part of the guidance.

Next, a good video shows site selection. The approved sites are the abdomen (at least a couple of centimetres from the navel), the outer thigh, and the upper arm. Each week, the injection goes into a different area or a fresh spot within the same area. Rotating sites is not optional; it prevents the build-up of lumpy tissue under the skin that can affect absorption over time.

The video should then demonstrate the actual injection: remove the pen cap, hold the pen firmly against the skin at a 90-degree angle, press and hold the injection button until the indicator confirms the dose is complete. The Wegovy pen is designed so there is no guesswork about when to stop. After the injection, do not rub the site. That is the full sequence, and if you want to read alongside any video, our page on how to administer Wegovy walks through every step in written form. Our page on administering Wegovy covers this in written form if you want to read alongside any video.

Does the injection technique change at higher doses?

This is a question our prescribers field regularly, and the short answer is no. The physical technique stays the same across every dose from the starting 0.25 mg through to the 2.4 mg maintenance dose. What changes is the pen itself, each dose tier uses a pen colour-coded and pre-set to that strength. You do not adjust anything; the pen does it.

The common misconception worth clearing up gently: many people assume that a higher dose means a bigger or more visible injection. It does not. The volume of liquid is small throughout, and the technique you learn on day one is the technique you will use a year in.

One practical note that videos sometimes gloss over: the pen must be replaced each week, not refilled. Each Wegovy pen contains four weekly doses. When you inject on your chosen day each week (say every Thursday) you use the same pen for four consecutive weeks, then start a fresh one. For guidance on choosing the right day, our page on the best time to administer Wegovy goes into the practical considerations in more detail.

If your dose is being increased, your prescriber will confirm the new pen strength and the timing of the change. Never increase the dose ahead of schedule, the titration exists to give your body time to adjust and to reduce the likelihood of nausea and other gastrointestinal effects.

What if the injection does not go to plan?

Occasionally the pen does not click, the liquid looks cloudy, or a small amount of the dose appears to leak after the injection. These are the moments where clear guidance matters most.

If the pen indicator does not confirm a complete dose, do not inject again. Contact your prescriber or the pharmacy that dispensed your treatment. The Wegovy SmPC on the eMC sets out the manufacturer's instructions for these scenarios and is the authoritative source, the Patient Information Leaflet inside your box summarises the same information in plain language.

Leakage of a tiny drop at the needle tip after the injection is normal and does not mean the dose was missed. A noticeable leak or a pen that makes no sound when activated is different, keep the pen and describe what happened when you call.

Injection-site reactions (mild redness, itching, or a small lump) are common at first and usually settle within a day or two. Persistent pain, significant swelling, or signs of infection at a site (warmth, spreading redness, pus) need a clinical assessment, not a wait-and-see approach. Reach our team through the contact page if you are unsure; aftercare support is available seven days a week.

On the question of side effects more broadly: most people who experience nausea find it is worst in the first couple of weeks at a new dose and then eases. Staying well hydrated and eating smaller portions helps. If you want to know more about what to expect as treatment progresses, our page on what happens on Wegovy covers the full picture.

Where can I find a reliable administration video?

The Novo Nordisk UK website (wegovy.co.uk) hosts official step-by-step animation and video for the Wegovy pen. These are produced by the manufacturer and aligned with the approved Patient Information Leaflet, they are the most accurate resource available and are updated when pen formats change.

The new single-dose 7.2 mg pen, approved by the MHRA in April 2026, has a slightly different auto-dosing mechanism from earlier pens, with a built-in covered needle that locks after use. If your prescriber has moved you to this higher dose, confirm you are watching the video specific to that pen format rather than an older one made for the 2.4 mg device.

If you have any uncertainty after watching (about the angle, the hold time, or what the indicator looks like when it is finished) our clinical team is available to talk it through. You can read about the team behind your care on the clinical team page. And if you are still in the process of deciding whether Wegovy is right for you, the Wegovy overview page pulls together the eligibility, evidence and process information in one place.

For context on what treatment costs privately in the UK, our Wegovy price comparison page gives an honest breakdown of what different providers include in their quoted figures. When you are ready to find out whether you are clinically suitable, you can check your eligibility through a free consultation, reviewed the same day by a named GPhC-registered prescriber.
