Wegovy pen pictures: what each pen looks like and how to recognise yours

How the Wegovy pen is built, and why the design helps first-time users

Every Wegovy pen shares the same basic anatomy. A clear viewing window sits near the base of the pen so you can see the liquid inside; the solution should look clear and colourless, without particles or cloudiness. At the top is a green start button, and a yellow injection indicator moves into view once the dose has been delivered. The needle is hidden inside a grey needle cap and covered by a needle shield that retracts automatically on contact with skin, you press, you hold for ten seconds, and the mechanism does the rest. Many people who are nervous about self-injecting find this reassuring. If you'd like a fuller explanation of how the device works in practice, the Wegovy pen guide covers each physical step in detail.

The pen is designed for single use only. Once you have injected your weekly dose, the device locks and the viewing window turns red. At that point it should go straight into a sharps container rather than a household bin. Never try to reuse a pen or remove the needle yourself.

Reading the colour coding, matching the label to your prescribed dose

This is the decision most people are trying to make when they search for pen pictures. Novo Nordisk uses a distinct colour band on each Wegovy pen's label, and the colour changes as the dose escalates. The titration pathway runs from 0.25 mg through 0.5 mg, 1.0 mg, 1.7 mg, to the 2.4 mg maintenance dose. The 0.25 mg starter pen and the higher-dose pens look almost identical in shape and size, colour coding is the fastest visual check that you have the right pen in hand. Before every injection, read the label: confirm the strength printed on it matches what your prescriber has prescribed, and check the expiry date.

The solution volume also changes slightly between doses. If you want to understand how the fill volume relates to the dose markings on the barrel, the Wegovy pen volume guide sets that out clearly. As a rule of thumb, if anything on the label looks unusual, the liquid appears discoloured, or the pen looks physically damaged, do not inject, contact your prescriber or pharmacist.

The MHRA's patient-level NHS information on semaglutide (Wegovy) includes a full list of what to check before injecting and when to seek urgent help; it's worth keeping that page bookmarked alongside your Patient Information Leaflet.

The pink pen, and what the newer 7.2 mg pen looks like

Many patients encounter the phrase Wegovy pink pen and wonder whether it refers to a specific dose. The pink branding is associated with the 1.7 mg device in the standard titration sequence, though device colours are subject to Novo Nordisk's packaging decisions and may vary by batch or market. Always treat the printed dose on the label as the definitive guide, colour is a useful secondary check, not the primary one.

In January 2026 a 7.2 mg maintenance dose received MHRA approval; in April 2026 a dedicated single-dose 7.2 mg pen followed, designed with an auto-dosing mechanism, built-in covered needle and a lock-after-use feature. The titration pathway to 7.2 mg still begins at 0.25 mg and steps up under prescriber guidance. Whether a specific pen format is available to you is something confirmed at clinical assessment, a prescriber considers your full health picture before any dose or format is confirmed.

Storage and the pre-injection routine

A question our prescribers hear regularly: does the pen need to come out of the fridge before injecting? The answer is in the Patient Information Leaflet (the authoritative source for your specific pen), but many patients find it most practical to keep pens on the fridge door shelf rather than at the back where temperatures can dip lower. The pen should not be frozen; if it has been, discard it.

Before injecting, most people build a brief routine: take the pen from the fridge, check the label and expiry, look through the viewing window, clean the injection site with an alcohol swab and let it dry, then attach to the skin and press the green button. The sites licensed for injection are the abdomen, the front of the thigh, or the upper arm, rotate each week to avoid tissue irritation. Inject a different spot within the same area, not the exact same point.

For context on how Wegovy compares with other semaglutide-based injections, it helps to understand that Ozempic contains the same active ingredient but carries a different licence, it is authorised for type 2 diabetes, not weight management. Wegovy is the weight-management licence. The weight-loss treatments overview explains the difference plainly if you're earlier in the decision process.
