How many clicks is 2.5mg on a 5mg Mounjaro pen?
Dial 30 clicks.
On a 5mg pen each click delivers 0.083mg, and a full dose is 60 clicks.
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 5mg pen you take the fraction of a full dose you need and multiply by 60:
(2.5 ÷ 5) × 60 = 30 clicks
That works out to about 0.083mg per click. Because you're dialling less than a full dose, a single pen can give roughly 8 doses of 2.5mg.
