Wegovy 1-click chart: reading the dose dial on your pen

Why the 1-click question matters: what the dial is actually telling you

The decision most Wegovy users face at some point is simple but surprisingly easy to second-guess: did I turn the pen enough, and did the last click count? Understanding what one click represents is the foundation of giving yourself an accurate, consistent dose every week.

Wegovy pens use a pre-set dial mechanism. You rotate the dose knob until the prescribed number appears in the window, then press the injection button. Each incremental movement of the knob is one click, and each click corresponds to a fixed increment of semaglutide volume. The number of clicks to reach your prescribed dose depends entirely on which dose you're taking. At 0.25 mg, the starting strength, you'll turn through fewer clicks than at 2.4 mg. That sounds obvious once stated, but it catches people out when they move to a new pen partway through a titration step.

A practical checking habit takes under a minute: before you inject, hold the pen at eye level and look straight at the dose window rather than at an angle. The number should sit flat and centred in the window, with no partial digit visible. If it looks even slightly off, dial back to zero and start again, the mechanism is designed to go both ways without wasting medicine. The full Wegovy pen clicks chart maps this out dose by dose if you want the complete reference alongside this explanation.

If you're ever uncertain after injecting whether the full dose was delivered, do not administer a second dose. Note the question in your record and raise it with your prescriber or the aftercare team before your next injection.

What changes as your dose increases through the titration schedule

The titration schedule exists to give your body time to adjust to semaglutide, and the click count shifts at each step. Moving from one maintenance level to the next means picking up a new pen card (or cartridge, depending on your supply format) and taking a moment to re-familiarise yourself with the new dial position before your first injection at that strength.

The licensed UK titration path for Wegovy runs from 0.25 mg, through 0.5 mg, 1.0 mg and 1.7 mg, up to 2.4 mg, each step typically held for around four weeks as directed by your prescriber. The MHRA approval of a 7.2 mg maintenance dose (and subsequently a dedicated single-dose 7.2 mg pen) expanded the ceiling for eligible adults, though the starting point and step timing remain clinically set, not self-directed. You can read more about how Wegovy works as a treatment and what the schedule involves at each stage.

At the 1.0 mg level specifically, the click count sits roughly mid-way between the lowest and highest doses on the standard path. If you want the precise figure mapped out, the 1.0 mg click reference covers that stage in detail. For the 2.4 mg maintenance dose, the 2.4 mg chart page gives you the full breakdown.

One thing to be aware of when you move to a higher dose pen: the resistance on the dial can feel slightly different. This is normal. It is not a sign the pen is faulty. Work through the clicks steadily rather than rushing, consistency in technique matters more than speed. The NHS semaglutide medicines page covers injection technique guidance you can cross-reference with your PIL.

Technique factors that affect whether each click lands cleanly

Even with the correct click count, the dose is only accurate if the technique around it is sound. This is the part the chart alone cannot tell you, and it is the reason how to take Wegovy injections is worth reading end to end before your first use, not just skimmed.

The three most common technique issues that affect dose accuracy are: not holding the injection button down for the full six seconds after the click of delivery (which can leave semaglutide on the skin surface rather than under it); injecting into an area with insufficient subcutaneous tissue; and failing to prime a new pen before the first use of that pen card. Priming dispenses a tiny amount of solution to clear the needle, it is a distinct step from your dose and should not be counted against your click total.

Injection sites for Wegovy are the abdomen, thigh, or upper arm. Rotate them each week. Cleaning the site first takes only a moment, and alcohol swabs are a straightforward way to keep that step consistent. After the injection, dispose of the used needle safely, a sharps container is the correct method and is required by UK guidance.

If a click feels or sounds different, or if you see air bubbles in the cartridge that seem unusually large, contact your prescriber or call the aftercare team before your next dose rather than guessing. Reporting suspected product defects via the MHRA Yellow Card scheme is also an option if you believe there is a manufacturing issue with the pen itself.

When to use this chart alongside clinical advice, not instead of it

A click chart is a reference tool. It answers a factual question about the pen mechanism. It does not replace the dosing instructions in your Patient Information Leaflet, and it cannot account for individual clinical decisions your prescriber has made, for example, holding you at a lower dose for longer because of side effects, or adjusting your schedule for another reason.

If your current dose or titration plan feels wrong, or if you have noticed something unexpected with the pen, that is a conversation for your prescriber. The UK-specific Wegovy click chart overview compiles the key reference information across all doses for easy comparison. For context on how this treatment sits alongside others, the treatment overview sets out the options available through a regulated UK private service.

Semaglutide (Wegovy) is available only on prescription following a clinical assessment by a qualified prescriber. If you have not yet started treatment and are weighing up whether this is right for you, check your eligibility with our prescribers, a GPhC-registered clinician reads every consultation personally, and the process is straightforward.
