Mounjaro Click Chart: KwikPen Clicks to mg Converter

GLP-1 Companion · 7 min read

If you are searching for a "Mounjaro click chart", you usually want the answer to one question: how many clicks on the KwikPen dial correspond to which dose in milligrams? The short answer: one full dose on the Mounjaro KwikPen is dialed over 60 clicks and delivers 0.6 ml — whether it is a 2.5 mg or a 15 mg pen. How much tirzepatide a single click represents therefore depends only on the pen strength.

What is the Mounjaro click chart?

The Mounjaro KwikPen used in the UK and Europe is a multi-dose pen: one cartridge holds four fixed weekly doses of 0.6 ml each. As you turn the dose dial, it advances in small audible, tactile steps — the community calls them "clicks". Because a full dose is dialed over 60 clicks, you can calculate what fraction of the dose a single click represents. That clicks-to-milligrams mapping is what people call the click chart (in German communities: "Klicktabelle").

It is mostly looked up by people who have agreed a slower titration or a microdosing protocol with their care team and want to understand how intermediate doses relate to the pen dial.

The click chart for every pen strength

Since every pen strength delivers its full dose over the same 60 clicks, the medication per click scales linearly with the strength:

• 2.5 mg pen: 60 clicks = 2.5 mg · 1 click ≈ 0.042 mg · 30 clicks ≈ 1.25 mg
• 5 mg pen: 60 clicks = 5 mg · 1 click ≈ 0.083 mg · 30 clicks ≈ 2.5 mg
• 7.5 mg pen: 60 clicks = 7.5 mg · 1 click ≈ 0.125 mg · 30 clicks ≈ 3.75 mg
• 10 mg pen: 60 clicks = 10 mg · 1 click ≈ 0.167 mg · 30 clicks ≈ 5 mg
• 12.5 mg pen: 60 clicks = 12.5 mg · 1 click ≈ 0.208 mg · 30 clicks ≈ 6.25 mg
• 15 mg pen: 60 clicks = 15 mg · 1 click ≈ 0.25 mg · 30 clicks ≈ 7.5 mg

Converting clicks to mg: the formula

The math behind every click chart is simple: dose per click = pen strength ÷ 60. In reverse: clicks = (target dose ÷ pen strength) × 60. Example: 1.25 mg on a 2.5 mg pen is (1.25 ÷ 2.5) × 60 = 30 clicks. The calculator above does this for every pen strength.

Why there is no official click chart

Mounjaro is tested and approved only for full doses following the licensed titration schedule. That is why Lilly publishes no clicks-to-mg mapping, and drawing partial doses is off-label use. On top of that, click counts can vary slightly between pen versions and batches, and after the four intended doses a small residual amount remains in the cartridge by design — it is not meant to be used.

Safety notes

• Discuss any deviation from your prescribed schedule with your doctor first — including slower titration or tapering off.
• Do not rely on counted clicks alone: miscounting, a different pen model, or batch variation can shift the actual dose.
• An opened pen has a limited in-use shelf life — stretching it across partial doses extends that window and can compromise the active ingredient.
• A click chart replaces neither the patient leaflet nor your prescriber’s instructions.

Frequently asked questions

How many clicks is 1.25 mg?

On the 2.5 mg pen, 1.25 mg works out to 30 clicks (half the full dose). On stronger pens it is proportionally fewer — about 15 clicks on the 5 mg pen.

Is it 60 clicks or 72? I have seen both.

Different figures circulate in forums, most often 60 or 72 clicks per full dose. The most widely shared figure — and the one consistent with the 0.6 ml delivered volume — is 60 clicks. Pen versions can differ, which is one more reason to treat click counts as a rough orientation only.

Does this chart apply to Zepbound or US Mounjaro pens?

No. These numbers apply to the multi-dose Mounjaro KwikPen used in the UK and Europe. US Mounjaro and Zepbound single-dose autoinjectors and vials work completely differently and have no clicks.

Can I use the click chart to microdose?

The chart only shows the arithmetic — it is not a recommendation to microdose. Whether a lower starting or maintenance dose makes sense for you is your care team’s call. If you do agree a protocol together, an app like Nuvo helps you log partial doses, weight, and side effects cleanly.
