"Click chart" is often used online to mean two different things. Some people use the term to describe unofficial tools that try to match pen clicks to tirzepatide doses. However, there is no manufacturer approved dosing chart that allows you to measure or adjust a Mounjaro dose by counting clicks.
What can be useful is a simple weekly injection log. You can use it to record your injection dates, prescribed strength, side effects and any questions you want to discuss with your prescriber. Mounjaro (tirzepatide) is authorised in the UK for type 2 diabetes and weight management in eligible adults.
For adults in the UK who have been prescribed Mounjaro for weight management, this guide explains what the term "click chart" really means, why click counting should not be used for dosing, how to set up a weekly tracking log and what you may want to record during treatment.
Key things to know
- There is no genuine per strength click chart for measuring or adjusting your Mounjaro dose
- Every Mounjaro KwikPen delivers a fixed 0.6ml volume per dose, regardless of strength. The amount of tirzepatide in that 0.6ml varies by strength
- The usual starting dose is 2.5mg once weekly for 4 weeks as part of your prescribed dosing schedule
- Your dose may be increased by 2.5mg after at least 4 weeks on your current dose, up to a maximum of 15mg once weekly, if recommended by your prescriber
- A useful "click chart" is better understood as a simple weekly injection tracking log, rather than a dosing tool
- Tracking your injections and symptoms can give your prescriber useful information during treatment reviews
Why a Dosing Click Chart Does Not Exist
According to the current UK product information, every Mounjaro KwikPen delivers a fixed 0.6ml dose. The available strengths include 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg. The volume remains 0.6ml, while the amount of tirzepatide in that volume changes according to the strength of the pen.
The Mounjaro KwikPen is a multiple dose pen containing 4 fixed doses. Its Instructions for Use explains how to prepare and use the pen, but click counting should not be used to work out a different dose.
This is particularly important when you see searches for a "10mg click chart". A chart that claims to tell you how many clicks to use for a particular dose could give the impression that you can adjust your prescribed dose mechanically. That is not how the Mounjaro dosing schedule is designed to work.
Whether you are prescribed 2.5mg, 5mg, 10mg or 15mg, use the strength prescribed for you and follow the Instructions for Use supplied with your pen. Do not use unofficial click calculations to create a lower or higher dose.
What a Genuinely Useful Click Chart Actually Is
If you are looking for a way to track your Mounjaro treatment, a simple weekly log can be much more useful than a click chart.
This is not about the pen's mechanics. It is simply a personal record of your injection dates, prescribed strength, symptoms and any questions you want to raise during your next review.
For example:
| Week | Injection date | Strength | Side effects noted | Notes |
|---|---|---|---|---|
| 1 | 2.5mg | |||
| 2 | 2.5mg | |||
| 3 | 2.5mg | |||
| 4 | 2.5mg | Review before next increase |
You can keep this record on paper, in a notes app or in a spreadsheet. The format does not matter as much as keeping the information accurate and easy to review.
There is no need to record mechanical clicks or calculate partial doses. Your prescribed strength and the instructions supplied with your pen are the important points to follow.
What to Actually Record Each Week
A few simple details can make your log useful without turning it into a chore:
- The date of your injection, so you can keep track of your weekly schedule
- Your current prescribed strength, especially when your dose changes
- Any side effects or symptoms you notice
- How you feel during the week, including changes in appetite or general wellbeing
- Any questions you want to ask your prescriber
Keeping a brief record may make it easier to describe how you have been feeling during a consultation. For example, you may be able to tell your prescriber when a symptom started and whether it happened around a dose increase.
You do not need to record every small detail. A few clear notes each week may be enough. The best tracking method is one that you can maintain consistently.
Why This Matters More Around Dose Increases
Mounjaro treatment usually starts at 2.5mg once a week for 4 weeks. The dose can then be increased in 2.5mg steps after at least 4 weeks on the current dose, when appropriate. The maximum adult dose is 15mg once weekly.
Digestive side effects such as nausea, diarrhoea and vomiting can occur with Mounjaro and may be more noticeable during dose increases. However, everyone responds differently, so it is useful to record what you actually experience rather than assuming that a particular symptom will occur.
If your log shows that a particular symptom appeared after a dose increase, you can mention this to your prescriber. They can then consider your symptoms alongside your overall treatment and decide whether any changes are appropriate.
Do not increase, reduce or split your prescribed dose based on your tracking log or the number of clicks on your pen.
Bringing Your Log to a Consultation
A simple and honest record can give your prescriber useful information during a treatment review. Do not worry if your log is incomplete. Bring whatever you have recorded and explain anything you remember that may be relevant.
Your prescriber can consider your notes alongside your medical history, current medicines, treatment response and any symptoms you have experienced.
If you are reviewing your treatment online, you can keep your log open during the consultation or simply have it available to refer to.
If you have questions about your dose, strength, or how to use your Mounjaro treatment correctly, start your free consultation and discuss them with your prescriber.

A tracking log can help you keep a record of your treatment, but it does not replace clinical monitoring by your prescriber. If you experience severe or concerning symptoms, seek medical advice promptly rather than waiting for your next scheduled review.
If you have questions about your dose, treatment progress or how to use your pen, speak with your prescriber, pharmacist or GP.
