ClickDose is a free browser-based tool that uses your phone's microphone to automatically count the clicks on your Wegovy pen. Instead of counting manually and risking errors, ClickDose listens to each click and tells you exactly when to stop dialing — making dose-splitting safer and more convenient.
Whether you are on a low starting dose or splitting a higher-strength pen, knowing the exact number of clicks per dose is essential. Below you will find complete click reference tables for every Wegovy pen strength.
How Many Clicks in a Wegovy Pen?

How Does Wegovy Click Counting Work?
Wegovy pens use a dial mechanism to measure doses. When you twist the dose knob, the pen produces a distinct clicking sound for each increment. Each click corresponds to a precise amount of semaglutide — the active ingredient in Wegovy. By counting these clicks, you can determine the exact dose being loaded into the pen before injection.
This click mechanism is the same across all Wegovy pen strengths, but the amount of medication delivered per click varies depending on the pen's concentration. That is why it is important to know the correct click-to-dose ratio for your specific pen strength.
Frequently Asked Questions
How many clicks is a full dose of Wegovy 2.4 mg?
A full dose of Wegovy 2.4 mg requires 75 clicks. The 2.4 mg pen contains 3 mL of solution and delivers 0.032 mg per click.
Can I split a Wegovy dose?
Yes, it is technically possible to split a Wegovy dose by counting a specific number of clicks to deliver a lower dose. However, dose-splitting is considered off-label use and is not officially recommended by the manufacturer. Always consult your doctor or pharmacist before splitting doses to ensure it is safe and appropriate for your situation.
How long does a Wegovy pen last after first use?
An opened Wegovy pen is stable for up to 8 weeks (56 days) after first use, when stored properly at room temperature below 30 °C (86 °F) or in the refrigerator. This makes multi-week dose-splitting practical from a single pen.
Is Wegovy click counting safe?
Click counting can be a useful guide for determining your dose, but it should always be verified visually using the dose window on the pen. Miscounting clicks can lead to receiving too much or too little medication. Tools like ClickDose help reduce the risk of counting errors by automating the process.
How does ClickDose count clicks?
ClickDose uses your device's microphone to detect the distinct clicking sound produced by the pen's dial mechanism. The app processes the audio in real time, counts each click as it happens, and alerts you when you have reached your target dose.
