Administering Wegovy on video: what the guides show, what they skip, and what to do before your first injection

The biggest myth: if you've watched the Novo Nordisk animation, you're ready to inject

Manufacturer animations are accurate, but they are designed for a broad audience and move quickly. People watching them often come away confident about the broad mechanics (cap off, pen to skin, button pressed) while remaining uncertain about the specifics that actually affect comfort and confidence on injection day. That gap is worth closing before you ever take a pen out of the box.

The Novo Nordisk pen has a built-in needle cover that activates when you press the pen firmly against the skin. You do not need to manually deploy or retract a needle. One of the most common first-injection mistakes is pressing the pen at an angle rather than flat and perpendicular to the skin surface, which can mean the needle does not insert cleanly. The NHS guidance on semaglutide recommends reviewing the full Patient Information Leaflet alongside any instructional resource, because the leaflet for your specific pen generation is the definitive reference, and pen designs can be updated between supply batches.

Another detail animations skip: the click you hear when you press the button is the start of injection, not the end. You hold the pen pressed to the skin until a second visual indicator (a number or colour change visible through the window) confirms the full dose has been delivered. Removing the pen before that point means a partial dose. Most people find this takes around ten seconds, though your leaflet gives the exact guidance for your pen.

If you want a thorough written walkthrough to read alongside any video, the step-by-step Wegovy administration guide on the nume site covers each stage in order, including what to check on the pen before you start.

What a good administering Wegovy video should actually show you

Not all instructional videos are equivalent. The most useful ones show the pen being handled at its actual size, demonstrate the skin-pinch technique for slimmer injection sites, and let you see the dose window before and after injection so you know what a complete dose looks like. Videos produced by the manufacturer, by NHS trusts, or by registered pharmacies tend to be more reliable than social-media clips, which sometimes demonstrate informal technique shortcuts that are not recommended in the SmPC.

Our Wegovy administration video guide walks through the full process at a pace suited to someone injecting for the first time, including the pre-injection checklist. The semaglutide administration video covers the same technique in the context of the active ingredient rather than the brand, which is useful if your prescriber has discussed the medicine in those terms.

One practical point worth knowing: if you are starting Wegovy around a bank holiday, the timing of your first delivery matters. Orders placed by 12pm on a working day are dispatched the same day for next-working-day delivery, so a Monday order before noon arrives Tuesday, but a Friday afternoon order arrives Monday. Planning your start date around that avoids your first pen sitting on a doorstep over a long weekend.

If you have any doubt about technique after watching a video, the full directions for administering Wegovy set out the process in writing, and you can also contact the aftercare team, who are available seven days a week.

Site rotation, storage, and the questions most people ask after the first injection

Injection site rotation is one of the details that gets lost between a video and real life. The three licensed sites are the abdomen (at least 5cm from the navel), the front of the thigh, and the outer upper arm. Each weekly injection should go to a different spot within these areas. Over time, injecting repeatedly into exactly the same point can cause lipohypertrophy (a build-up of fatty tissue under the skin that affects absorption) so genuine rotation across the full area matters, not just switching between sites.

Storage is straightforward in principle but catches people out when travelling or during hot weather. Wegovy is kept refrigerated at 2–8°C. Once removed from the fridge it can be kept at room temperature, but for a defined window only, the SmPC on the electronic Medicines Compendium gives the exact figure for your specific product version, and that is the figure to follow rather than any general estimate you may have seen online. Never freeze the pen, and keep it away from direct sunlight.

A question our prescribers hear regularly: "A small bubble of liquid appeared at the injection site, did I lose the dose?" In most cases, no. A tiny bead of fluid is common after subcutaneous injection and does not represent a meaningful loss of medicine. What matters is that the dose window showed completion before you removed the pen. If you are ever unsure whether a full dose was delivered, the right person to ask is your prescriber, not a forum.

For a broader look at how semaglutide works and what to expect during treatment, the semaglutide overview covers the mechanism, the evidence base, and the licensed indications in plain language. If you are still in the process of deciding whether Wegovy is right for you, the Wegovy treatment page sets out eligibility and how the process works at nume.

If you are ready to start, our prescribers review consultations the same day they arrive, a real clinician reads your answers, not software. You can start your free consultation at any point, with no commitment required.
