If you use Ozempic (semaglutide) and need to count the clicks on your FlexPen, ClickDose can help. ClickDose is a free web-based tool that listens to the clicks of your injection pen through your phone's microphone and counts them automatically. No more manual counting, no more guessing — just select your Ozempic pen strength and target dose, and ClickDose tells you exactly when to stop dialing.
How Many Clicks in an Ozempic Pen?
All Ozempic FlexPen strengths deliver a fixed 0.01 mg per click. This makes the math straightforward: divide your desired dose (in mg) by 0.01 to get the number of clicks. Below is a quick reference table for every Ozempic pen.
Ozempic 2 mg pen (1.5 mL)
| Dose | Clicks |
|---|
| 0.25 mg | 25 clicks |
| 0.5 mg | 50 clicks |
Ozempic 4 mg pen (3 mL)
| Dose | Clicks |
|---|
| 0.5 mg | 50 clicks |
| 1.0 mg | 100 clicks |
Ozempic 8 mg pen (3 mL)
| Dose | Clicks |
|---|
| 1.0 mg | 100 clicks |
| 2.0 mg | 200 clicks |
How Ozempic FlexPen Dose Dial Works
The Ozempic FlexPen uses a twist-dial mechanism at the end of the pen. Each click of the dial advances the dose by exactly 0.01 mg. You turn the dial to set your dose, then press the injection button to deliver the medication. The dial is adjustable — if you go past your target, you can turn it back without wasting any medication.
Because every click equals the same amount regardless of pen strength, counting clicks is the most reliable way to set a precise dose, especially when dose-splitting from a larger pen.
