How it's worked out

Every Mounjaro KwikPen gives a full labelled dose in 60 clicks, whatever its strength. To get a 2.5mg dose from a 2.5mg pen you take the fraction of a full dose you need and multiply by 60:

(2.5 ÷ 2.5) × 60 = 60 clicks

That works out to about 0.042mg per click, or 0.6ml for the whole 2.5mg 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.
