Wegovy pen clicks chart: reading your dose at a glance

The decision you are probably trying to make: did I get the full dose?

Most people searching for a Wegovy clicks chart are really asking one of two things: either they want to check they used the pen correctly, or they are trying to work out which pen to use next. Both are sensible. The pen mechanism involves an audible and tactile clicking as you press the injection button, and because the number of clicks varies between doses, it is understandable that people use it as a rough check. The honest answer is that click count is a useful signal but not the primary measure, the dose counter window is.

Once you press and hold the injection button, keep it held for a slow count of six after the clicking stops. Then release and withdraw the pen. Check the counter: a reading of '0' confirms the full pre-set dose has been delivered. If the counter has not returned to zero, some of the dose may remain in the pen. The NHS semaglutide medicines page and the patient information leaflet that comes with your pen both walk through this check step by step, keep that leaflet to hand, especially when starting on a new strength.

For a more detailed breakdown of how the click count maps to specific dose strengths, the Wegovy clicks guide on this site covers the mechanics pen by pen.

Colour, clicks and counter: what the Wegovy pen chart shows by dose

Wegovy uses a graduated titration schedule, you begin at a low dose and your prescriber moves you up when the time is right. Each step has its own colour-coded pen. This matters practically: if you receive a new box and the pen colour has changed, that is expected and intentional; it reflects a dose increase your prescriber has authorised. Opening a box to find the previous colour when you were expecting an upgrade (or vice versa) is worth querying with your prescriber or pharmacy before injecting.

The click count per dose is fixed by the pen's internal mechanism and is not something you adjust. As doses increase, the click sequences change, a detail that catches people out when they move from, say, 1.0 mg to 1.7 mg and the pen behaves differently in their hand. The Wegovy click chart for UK pen formats sets out each strength's colour and counter behaviour specifically. And if you are already on the 2.4 mg maintenance dose and want the full click reference for that pen, there is a dedicated 2.4 mg Wegovy click chart that goes into that pen's specifics.

One practical note: when your pen arrives (tracked to your door by DPD in plain, unbranded packaging) inspect the pen barrel before your first injection. The label on the pen itself states the strength; read that alongside the box. Never inject from a pen whose label you cannot read clearly.

Why click count alone can mislead, and the checks that actually protect you

The click count varies between the five Wegovy strengths, and it can also be affected by how firmly you hold the pen against the skin, whether your grip shifts mid-injection, and ambient temperature. None of that means the pen has failed, but it does mean that counting clicks and stopping there is not a robust safety check. The dose counter exists precisely because clicks are mechanical and variable; the counter is the authoritative readout.

There is also a practical concern around pen storage and handling. Wegovy pens must be kept refrigerated at 2–8°C; the patient information leaflet sets out the limited window for room-temperature use, and the eMC product page for Wegovy holds the full summary of product characteristics, including storage detail. A pen that has been left warm for too long may still click normally but could be less effective. That is another reason the counter and the condition of the pen together matter more than the sound alone.

If at any injection you are unsure whether the full dose went in (counter did not reach zero, pen slipped, site bled unexpectedly) the right step is to contact your prescriber rather than inject again. Double-dosing is not the answer. Your frequently asked questions page covers a number of real situations like this, or you can reach the nume support team directly.

Where the clicks chart fits into your broader Wegovy journey

The clicks chart is one small part of understanding how to use your pen confidently. It sits alongside questions about dose titration timing, what to do if you miss a weekly injection, how to rotate injection sites, and how to read the signals your body gives as treatment progresses. None of those decisions should rest on a chart alone, they belong in a conversation with a prescriber who knows your history.

Wegovy is semaglutide, a GLP-1 receptor agonist, and the treatment pathway runs from 0.25 mg through to 2.4 mg (or the newer 7.2 mg maintenance dose for those who move to that format), with each step authorised by a clinician based on tolerability and response. If you want a quick reference to confirm your current settings before injecting, the Wegovy 1 click chart lets you check your dose details in a single step. For people considering whether to begin, or thinking about switching from a different medicine, our page covering weight loss injections including Ozempic covers the landscape without the jargon.

Semaglutide's licensed indication is weight management in adults, as detailed in the NICE technology appraisal TA875; treatment should always sit within a clinical framework that includes diet, activity and regular review. That framework is exactly what a prescriber-led service provides. If you have questions about your pen, your dose, or whether Wegovy is still the right fit for you, you may also find the Wegovy click chart 10 a useful reference as you work through those pen specifics with your clinician.
