ClickDose is a free, browser-based tool that listens to your Mounjaro KwikPen through your phone's microphone and counts every click automatically. No app to install, no manual counting, no guesswork — just accurate, real-time click detection so you always know your exact tirzepatide dose.
How Many Clicks in a Mounjaro KwikPen?
Every Mounjaro KwikPen — from 2.5 mg to 15 mg — contains exactly 60 clicks. The pens all deliver the same volume of liquid; what changes is the concentration of tirzepatide. Here is the mg per click for each pen strength:
| Pen Strength | Clicks | mg per Click |
|---|---|---|
| 2.5 mg | 60 | 0.04 mg |
| 5 mg | 60 | 0.08 mg |
| 7.5 mg | 60 | 0.13 mg |
| 10 mg | 60 | 0.17 mg |
| 12.5 mg | 60 | 0.21 mg |
| 15 mg | 60 | 0.25 mg |
Half-dose tip: 30 clicks = half a dose. This is useful for patients who split doses for slower titration or cost saving. Dose splitting is off-label — always discuss with your doctor first.
How Mounjaro KwikPen Works
The Mounjaro KwikPen is a disposable, pre-filled injection pen made by Eli Lilly. Unlike Wegovy and Ozempic pens (which vary in click count by strength), every Mounjaro pen uses the same mechanical design: 60 clicks delivering a fixed volume. The difference between a 2.5 mg pen and a 15 mg pen is purely the concentration of tirzepatide in the solution — not the number of clicks or the volume injected.
This consistent 60-click mechanism makes Mounjaro particularly well suited for click counting and dose splitting. Once you know how many clicks correspond to your desired dose, the math is the same for every pen strength.
Frequently Asked Questions
How many clicks are in a Mounjaro pen?
Every Mounjaro KwikPen contains exactly 60 clicks, regardless of the pen strength. Whether you have a 2.5 mg pen or a 15 mg pen, the mechanical click count is always 60.
Can you split a Mounjaro dose?
Yes. Because every KwikPen has 60 clicks, you can dial 30 clicks for a half dose. For example, 30 clicks on a 5 mg pen delivers 2.5 mg. This is off-label use and should be discussed with your prescribing doctor before attempting.
Is the Mounjaro KwikPen single-dose?
The KwikPen is marketed as a single-dose device — one pen, one injection. However, mechanically it contains 60 individually clickable increments, so it is possible to use it for multiple smaller injections via click counting. This is off-label, and you must use a new sterile needle for each injection and store the pen correctly between uses.
How long does a Mounjaro pen last after first use?
Once punctured, a Mounjaro KwikPen must be used within 21 days when stored at room temperature (up to 30 °C). This is shorter than Wegovy, which allows 28 days. If you are splitting doses, plan your injections accordingly.
What is the difference between Mounjaro and Wegovy?
Mounjaro contains tirzepatide, a dual GIP and GLP-1 receptor agonist that acts on two incretin hormones. Wegovy contains semaglutide, which targets only the GLP-1 receptor. Both medications promote weight loss and blood sugar control, but their mechanisms differ. Mounjaro's dual action may produce different efficacy and side-effect profiles compared to Wegovy.
