Mounjaro Click Chart (UK)
Full KwikPen Click Guide

See exactly how many clicks correspond to every Mounjaro dose across all UK pen strengths.

Monj independently analyses UK Mounjaro dosing mechanics using publicly available prescribing data and device specifications.

Every full Mounjaro dose is exactly 60 clicks on a UK KwikPen. To work out how many clicks you need, divide your dose by the pen strength and multiply by 60.

The KwikPen Click Formula

All Mounjaro KwikPens use the same mechanical ratio.

(Desired Dose ÷ Pen Strength) × 60 = Clicks
Examples:
2.5mg from a 5mg pen = 30 clicks
5mg from a 7.5mg pen = 40 clicks

Understanding Pen Mechanics

60 Clicks Per Full Dose

Irrespective of whether you hold a 2.5mg pen or a 15mg pen, the mechanical dial inside the UK KwikPen is calibrated exactly the same. One full dose equals exactly 60 clicks, dispensing a volume of 0.6ml.

Linear Calibration

Because the mechanism is strictly linear, fractional dosing follows a direct mathematical ratio. This consistency allows users and healthcare professionals to map exact dosages by simply counting clicks. For comprehensive breakdown costs alongside dosing, use the full tool instead.

Important Safety Information
Mounjaro is a prescription-only medication. This guide is not medical advice. Altering your dosage without guidance from your prescriber can be dangerous. Please report any suspected side effects directly to the MHRA via the Yellow Card Scheme.
