Important: How This Informational Guide Works
- Find dose strength in the top row
- Look across strength to see how many clicks = dose
- Bold numbers (60 clicks) indicate using the pen's full dose as per manufacturer guidance
⚠️ Always use your pen as prescribed by your healthcare provider. Do not attempt to adjust doses by counting clicks.
What is the Mounjaro Click Chart?
Many people using Mounjaro (tirzepatide) notice clicking sounds when using their KwikPen injection device. The "click chart" is an informal reference guide that patient communities have created to document the number of clicks commonly heard during injection at different dose levels.
Important to understand:
- The click chart is NOT an official Lilly medical tool
- It should NOT replace your prescriber's instructions
- Clicks are simply audible feedback from the pen mechanism
- Your prescriber will provide proper injection training
The clicks you hear are a normal part of how the pre-filled pen delivers medication. Many patients find knowing what to expect reassuring, particularly when starting treatment or increasing doses.
The table above shows patterns commonly reported by patients. This information comes from patient communities and should be used alongside official guidance from your healthcare provider.
Note: Always verify you're using the correct colour-coded pen for your prescribed dose.
How the Mounjaro KwikPen Works
The KwikPen is a pre-filled, single-use injection device. Each pen is:
- Colour-coded by dose strength for easy identification
- Pre-measured with the exact dose prescribed
- Designed for single use - each pen delivers one injection
- Temperature-sensitive - requires proper storage
The clicking sound comes from the pen's internal mechanism as you get it ready to deliver the medication. These clicks provide audible feedback that you are loading the pen correctly.
What the clicks mean:
- Clicks are normal and expected
- They indicate the pen mechanism is working
- The number of clicks is consistent for all dose strengths
- Hearing clicks does NOT mean something is wrong
What to Do If Something Feels Wrong
While clicks are normal, contact your prescriber or pharmacist if you experience:
- No clicks at all when loading the pen
- Pen feels jammed or won't activate
- Visible medication leakage before, during, or after injection
- Unusual resistance when pressing the injection button
- Uncertainty about whether the full dose was delivered
- Pain, redness, or swelling at the injection site that doesn't resolve
Your healthcare provider can check your injection technique and ensure you're using the pen correctly.
Proper Storage and Handling
To ensure your Mounjaro pen works correctly:
- Before first use: Store in refrigerator (2°C to 8°C)
- Do not freeze
- Keep in original packaging to protect from light
After first use:
- Can be stored at room temperature (up to 30°C) for up to 21 days OR continue refrigerating
- Keep cap on when not in use
- Always: Check expiry date before use
- Inspect pen for damage or discolouration
- Verify you have the correct dose strength (check colour coding)
Getting Support from Your Pharmacy
UK pharmacies vary in the level of ongoing support they provide for weight loss treatment:
Support levels differ:
- Some offer 24/7 clinical access for questions
- Others provide detailed injection training materials
- Response times for queries vary significantly
- Follow-up consultation frequency differs
If you're unsure about your injection technique or have questions about clicks, contact your prescribing pharmacy. They should provide guidance or connect you with a clinician.

Frequently Asked Questions
Q: Is it normal to hear clicks?
A: Yes, clicks are completely normal feedback from the pen mechanism. All dose strengths produce similar clicking sounds.
Q: What if I don't hear any clicks?
A: Contact your pharmacy or prescriber. The pen may not have activated properly, and you should verify whether the dose was delivered.
Q: Do more clicks mean a higher dose?
A: No. All Mounjaro dose strengths produce 60 clicks for 1 dose. The dose is determined by the concentration in the pen, not the number of clicks.
Q: Can I count clicks to verify my dose?
A: The colour-coding on your pen box is the official way to verify your dose strength. Clicks are just audible feedback, not a dosing mechanism.
Q: Should I stop loading if I reach a certain number of clicks?
A: Always follow your prescriber's instructions for using the pen. Continue loading the dose as per the instructions.
