Ozempic Click Chart and Wegovy Pen Clicks by Concentration
An Ozempic click chart rests on an unofficial 0.01 mL per click: 0.25 mg is about 37 clicks at 0.68 mg/mL and 19 at 1.34 mg/mL. Novo says not to count.

An Ozempic click chart is unofficial arithmetic: Novo Nordisk’s Ozempic and Wegovy instructions give no volume per click and say “Do not set the dose by counting the number of clicks you hear” (Ozempic instructions). The 0.01 mL per click comes from a Canadian clinic handout (BC Diabetes). On that assumption, 18 clicks hold about 0.12 mg at 0.68 mg/mL and about 0.58 mg at 3.2 mg/mL (Ozempic, Wegovy).

Key facts
- Ozempic and Wegovy dial pens come in five concentrations, from 0.68 to 3.2 mg/mL (Ozempic label, Wegovy 1.7 mg, Wegovy 2.4 mg).
- A labeled dial-pen dose is 0.19, 0.37, 0.74 or 0.75 mL depending on the pen (Ozempic 0.25 mg, Ozempic 0.5 mg, Wegovy).
- The US Wegovy FlexTouch holds 4 doses of 2.4 mg and cannot select another dose (US Wegovy label).
- US Wegovy single-dose pens, including 7.2 mg, have no dose dial (US Wegovy label).
- Novo Nordisk’s instructions give no volume per click; BC Diabetes prints “Each click = 0.01 ml in volume” while BC Children’s prints “1 click = 0.01 mg” (Ozempic instructions, BC Diabetes, BC Children’s).
- On a US Ozempic pen, 2 mg/3 mL, 4 mg/3 mL and 8 mg/3 mL are total contents; the 4 mg/3 mL pen’s labeled dose is 1 mg (US label).
What does Novo Nordisk say about counting Ozempic and Wegovy clicks?
For Ozempic and Wegovy, Novo Nordisk says to select the dose with the dose counter and not to count clicks (Ozempic instructions, Wegovy leaflet).
Do not set the dose by counting the number of clicks you hear (Ozempic Instructions for Use).
The same wording appears in the UK Wegovy leaflet and Canadian Wegovy instructions. The US Wegovy FlexTouch instructions carry the same line.
For other devices, use the explanation of what clicks mean on Zepbound and Mounjaro pens.
Why do Ozempic click charts disagree?
Click charts disagree because the Canadian handouts use different click sizes (BC Children’s, BC Diabetes). Ozempic and Wegovy pens also have different concentrations (Ozempic, Wegovy).
BC Children’s lists 18 clicks for 0.25 mg and 72 for 1 mg (handout); BC Diabetes lists 75 for 2.4 mg (handout). The 0.01 mL model gives about 37 clicks for 0.25 mg at 0.68 mg/mL and 19 at 1.34 mg/mL (assumption, concentrations). Under that assumption, the labeled 0.74 and 0.75 mL volumes correspond to 74 and 75 clicks (Ozempic, Wegovy).
The BC Children’s handout prints “1 click = 0.01 mg,” which makes 72 clicks equal 0.72 mg when read literally, contradicting its table’s 1 mg (handout). If the handout’s 1 mg pen delivers 0.74 mL a dose, as the UK 4 mg/3 mL label prints, 72 clicks would be about 0.0103 mL each, not 0.01 mL (handout, label).
What concentration is each Ozempic and Wegovy pen?

Ozempic and Wegovy dial pens span concentrations from 0.68 to 3.2 mg/mL, with different dose volumes (US Ozempic label, UK Wegovy SmPC).
UK values follow the Ozempic labels for 0.25 mg, 0.5 mg, 1 mg and 2 mg and the Wegovy labels for 0.25 mg, 0.5 mg, 1 mg, 1.7 mg and 2.4 mg. US dose volumes are calculated from the dose and concentration in the Ozempic and Wegovy labels.
| Pen | Concentration (mg/mL) | Dose volume (mL) |
|---|---|---|
| UK Ozempic 0.25 mg | 1.34 | 0.19 |
| UK Ozempic 0.5 mg, 1.5 mL pen | 1.34 | 0.37 |
| UK Ozempic 0.5 mg, 3 mL pen | 0.68 | 0.74 |
| UK Ozempic 1 mg, 4 mg/3 mL pen | 1.34 | 0.74 |
| UK Ozempic 1 mg, 8 mg/3 mL pen | 2.68 | 0.37 |
| UK Ozempic 2 mg | 2.68 | 0.74 |
| UK Wegovy 0.25 mg | 0.68 | 0.37 |
| UK Wegovy 0.5 mg, 1.5 mL pen | 1.34 | 0.37 |
| UK Wegovy 0.5 mg, 3 mL pen | 0.68 | 0.75 |
| UK Wegovy 1 mg | 1.34 | 0.75 |
| UK Wegovy 1.7 mg | 2.27 | 0.75 |
| UK Wegovy 2.4 mg | 3.2 | 0.75 |
| US Ozempic 2 mg/3 mL, 0.25 mg dose | 0.68 | About 0.37, calculated |
| US Ozempic 2 mg/3 mL, 0.5 mg dose | 0.68 | About 0.74, calculated |
| US Ozempic 4 mg/3 mL, 1 mg dose | 1.34 | About 0.75, calculated |
| US Ozempic 8 mg/3 mL, 2 mg dose | 2.68 | About 0.75, calculated |
| US Wegovy FlexTouch, 2.4 mg dose | 3.2 | 0.75, calculated |
Canada’s Wegovy FlexTouch pens use the same five concentrations, and its 2.4 mg pen also holds 9.6 mg in 3 mL (Canadian monograph). Any UK Wegovy pen clicks chart has to start from this table, because the 0.5 mg pen alone comes at 0.68 or 1.34 mg/mL (UK Wegovy 0.5 mg SmPC).
For 1 mg at 1.34 mg/mL, UK Ozempic prints 0.74 mL and UK Wegovy 0.75 mL (Ozempic, Wegovy). That is 74 or 75 clicks on the unofficial 0.01 mL assumption (BC Diabetes).
How many clicks is 0.25 mg of Ozempic?
An Ozempic dosing chart in clicks rests on the unofficial 0.01 mL per click; on it, 0.25 mg of Ozempic is about 37 clicks at 0.68 mg/mL or 19 at 1.34 mg/mL (assumption, label).
This arithmetic table applies the unofficial 0.01 mL per click to labeled concentrations in US Ozempic, Wegovy 1.7 mg and Wegovy 2.4 mg.
| Concentration (mg/mL) | One click, assumed (mg) | 0.25 mg, assumed clicks |
|---|---|---|
| 0.68 | 0.0068 | About 37 |
| 1.34 | 0.0134 | About 19 |
| 2.27 | 0.0227 | About 11 |
| 2.68 | 0.0268 | About 9 |
| 3.2 | 0.032 | About 8 |
Pens labeled for 0.25 mg include US Ozempic 2 mg/3 mL at 0.68 mg/mL and UK Ozempic 0.25 mg at 1.34 mg/mL (US, UK). UK Wegovy 0.25 mg contains 0.68 mg/mL (SmPC). On each, the counter sets 0.25 mg; click counts are not a Novo Nordisk setting (Ozempic instructions, Wegovy leaflet).
What would 18 clicks deliver on each pen?
For Ozempic and Wegovy, 18 clicks represent about 0.12 to 0.58 mg under the unofficial assumption (BC Diabetes, Wegovy concentration).
This derived table applies the unofficial 0.01 mL per click to labeled concentrations in US Ozempic, UK Wegovy 0.25 mg, 1 mg, 1.7 mg, 2.4 mg and Canadian Wegovy.
| Concentration (mg/mL) | 18 clicks, assumed (mg) | Examples of pens at this concentration |
|---|---|---|
| 0.68 | About 0.12 | US Ozempic 2 mg/3 mL; UK Wegovy 0.25 mg |
| 1.34 | About 0.24 | US Ozempic 4 mg/3 mL; UK Wegovy 1 mg |
| 2.27 | About 0.41 | UK and Canadian Wegovy 1.7 mg FlexTouch |
| 2.68 | About 0.48 | US Ozempic 8 mg/3 mL; UK Ozempic 2 mg |
| 3.2 | About 0.58 | US, UK and Canadian Wegovy 2.4 mg FlexTouch |
Use the dose counter to set the dose on a new pen, without carrying over a click count (Ozempic instructions, Wegovy leaflet). If the new pen comes with a switch from Mounjaro, see switching from Mounjaro to Wegovy for the starting dose.
What does a Wegovy click chart give for 2.4 mg in the UK, Canada and US?
For a Wegovy 2.4 mg FlexTouch pen, 75 clicks is the BC Diabetes handout’s unofficial figure (handout). Wegovy 2.4 mg single-dose pens in the US and Canada have no dose dial (US label, Canadian monograph).
UK and Canadian Wegovy 2.4 mg FlexTouch pens contain 9.6 mg/3 mL at 3.2 mg/mL (UK SmPC, Canadian monograph).
BC Children’s 72 clicks is for a 1 mg dose (handout). On the 0.01 mL assumption, a 0.74 mL dose is 74 clicks and a 0.75 mL dose is 75 (BC Diabetes). The US FlexTouch selects only 2.4 mg (US instructions).
Which Ozempic and Wegovy pens can be dialed in the US, UK and Canada?
Ozempic pens and Wegovy FlexTouch pens have dose selectors; single-dose Wegovy pens do not (Ozempic, Wegovy).
The device table follows US Ozempic and Wegovy labels, UK Wegovy 2.4 mg and 7.2 mg labels, and Canadian Ozempic and Wegovy monographs.
| Market | Pens with a dose dial | Devices with no dose dial |
|---|---|---|
| US | Ozempic pens; Wegovy FlexTouch, 2.4 mg only | Wegovy single-dose pens 0.25 to 7.2 mg; Ozempic and Wegovy syringes |
| UK | Ozempic pens; Wegovy FlexTouch 0.25 to 2.4 mg | Wegovy 7.2 mg single-dose pen |
| Canada | Ozempic pens; Wegovy FlexTouch 0.25 to 2.4 mg | Wegovy single-use pens 0.25 to 2.4 mg |
Canada sells both Wegovy FlexTouch and fixed-dose single-use pens, so country alone does not identify your device (Canadian monograph).
You can keep a consistent record in mg as your pen strength or dose step changes. In Pensday, log mg, not clicks, in the shots log; the free estimated medication-level curve uses that dose. Side effects logged against your dose cycle and a weight report colored by dose show how each step sits with you.
If your semaglutide comes in a vial measured in syringe units, use the semaglutide dose calculator to convert mg to units.
Where does the 0.01 mL per click figure come from?
For Ozempic and Wegovy, the 0.01 mL per click assumption comes from the BC Diabetes handout, which states “Each click = 0.01 ml in volume” (handout).
Novo Nordisk’s US Ozempic and UK Wegovy instructions give no volume per click (Ozempic, Wegovy). Neither do the Canadian monographs (Canadian Wegovy monograph).
The BC Children’s Hospital handout calls its method “off-label” and “not recommended by the manufacturer” (handout). A Diabetes Care letter says no clinical trials have validated click dosing’s safety or efficacy (Komé et al., 2025).
For the separate tirzepatide device question, use the Mounjaro click chart.
What are the licensed options instead of a part dose?

For a difficult Wegovy step, the UK SmPC says, “In case of significant gastrointestinal symptoms, consider delaying dose escalation or lowering to the previous dose until symptoms have improved” (SmPC).
For an intolerable Wegovy dose during escalation, the US label says to “consider delaying dosage escalation for 4 weeks” (US label).
The UK Wegovy SmPC states, “To reduce the likelihood of gastrointestinal symptoms, the dose should be escalated over a 16-week period” (SmPC).
US Ozempic starts at 0.25 mg weekly for 4 weeks, then 0.5 mg; further increases follow at least 4 weeks on the current dose (US label). Wegovy also starts at 0.25 mg, with labeled escalation steps (SmPC). Compare the steps using the Ozempic and Wegovy dose ladders.
A microdosing Wegovy click chart uses an off-label method, and a Diabetes Care letter says no clinical trials have validated its safety or efficacy (letter).
Questions
Frequently asked questions
How many clicks is 0.5 mg on a 1 mg Wegovy pen?
For UK and Canadian Wegovy 1 mg FlexTouch pens at 1.34 mg/mL, the unofficial 0.01 mL per click gives about 37 clicks for 0.5 mg (assumption, Canadian monograph). The pen is labeled for 1 mg doses, and Wegovy’s instructions say not to count clicks (SmPC, leaflet). The US Wegovy 1 mg single-dose pen has no dial (US label).
What is 30 clicks of Wegovy?
On the unofficial 0.01 mL assumption, 30 Wegovy clicks represent about 0.2 mg at 0.68 mg/mL or 0.4 mg at 1.34 mg/mL (assumption, concentrations). At 2.27 mg/mL, the assumed amount is about 0.68 mg; at 3.2 mg/mL, it is 0.96 mg (assumption, concentrations). The Wegovy leaflet says, “Do not set the dose by counting the number of clicks you hear” (leaflet).
How many clicks are in a 4 mg Ozempic pen?
The Ozempic 4 mg/3 mL pen delivers 4 labeled doses of 1 mg, and its instructions give no click count (US label). Its UK 1 mg dose volume is 0.74 mL, corresponding to about 74 clicks per dose under the unofficial 0.01 mL per click assumption (UK SmPC, assumption). That assumed count is per 1 mg dose, not for the whole pen.
How many clicks is 1 mg on a 2 mg Ozempic pen?
For the US Ozempic pen that delivers 2 mg doses, the unofficial 0.01 mL per click gives about 37 clicks for 1 mg (assumption, label). That pen holds 8 mg/3 mL at 2.68 mg/mL and is labeled for 4 doses of 2 mg; it is not the 2 mg/3 mL starter pen (US label). The UK also sells an 8 mg/3 mL pen labeled for 8 doses of 1 mg, each 0.37 mL (UK SmPC).
What if I dialed the wrong Ozempic dose or took too much?
Before injecting Ozempic, check the dose counter; the instructions say, “If you select the wrong dose, you can turn the dose selector forward or backwards to the correct dose” (instructions). If you took too much Ozempic, its US guide says, “call your healthcare provider or Poison Help line at 1-800-222-1222 or go to the nearest hospital emergency room right away” (Medication Guide). For excess Wegovy, the UK leaflet says, “Talk to your doctor straight away,” and warns of nausea (leaflet).
