How it's worked out

Every Mounjaro KwikPen gives a full labelled dose in 60 clicks, whatever its strength. To get a 10mg dose from a 12.5mg pen you take the fraction of a full dose you need and multiply by 60:

(10 ÷ 12.5) × 60 = 48 clicks

That works out to about 0.208mg per click, or 0.48ml for the whole 10mg dose. Because you're dialling less than the pen's full 12.5mg dose, a single pen stretches to roughly 5 doses of 10mg — about 5 weeks if you inject once a week, versus four weeks at the full dose.

A KwikPen holds 240 usable clicks in total (four full doses). If you're mixing dose sizes from one pen — for example while titrating up — the pen tracker keeps a running total of what's left, and the titration planner maps the clicks for each step.

Frequently asked questions

How many clicks is 10mg on a 12.5mg Mounjaro pen?
Dial 48 clicks. A 12.5mg KwikPen delivers 0.208mg per click (60 clicks = the full 12.5mg dose), so a 10mg dose is (10 ÷ 12.5) × 60 = 48 clicks.
How many 10mg doses are in a 12.5mg pen?
A pen holds 240 usable clicks, so at 48 clicks per dose you get about 5 10mg doses per pen — more than the four full doses, because you're dialling a partial dose. Injecting weekly, that's roughly 5 weeks per pen.
How much medicine is one click on a 12.5mg pen?
Every click releases the same 0.01ml of liquid; on a 12.5mg pen that's 0.208mg. Your 10mg dose works out to 0.48ml (48 clicks).
