How the Click Method Works on Mounjaro and Wegovy Pens
Both Mounjaro (tirzepatide) and Wegovy (semaglutide) are supplied as pre-filled injection pens designed for once-weekly self-injection. During an injection, the pen produces a series of audible and sometimes tactile clicks as the medicine is delivered. Many people use these clicks as a way to confirm the dose is being administered fully — this is often called the click counter or click method.
Why clicks matter
Releasing the pen button or moving the device before the full dose has been delivered can result in an incomplete injection. Counting clicks — or listening for the injection to finish before removing the pen — is a practical habit that many users find reassuring. The exact number of clicks can vary depending on the pen design and dose strength, so always refer to the patient information leaflet (PIL) that came with your specific pen, or ask your prescriber or pharmacist to walk you through the injection process for your device.
A note on dose strengths
Mounjaro is available in several dose strengths — commonly 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg — and your prescriber decides which strength is right for you at each stage of your treatment. The number of clicks associated with a complete injection may differ between strengths and pen types, so checking your leaflet each time you start a new pen is good practice. Your prescriber or pharmacist is the right person to clarify any uncertainty about your specific device.
Click counting on Wegovy pens
The same principle applies to the Wegovy (semaglutide) pen. Users of both medicines sometimes search for a click counter for Wegovy to cross-check their injection technique. As with Mounjaro, the PIL for your Wegovy pen is the definitive reference for how many clicks indicate a completed dose — the number can vary by dose stage.
For a broader view of how dose stages work and how tracking fits in, see our Mounjaro dose guide and calculator. If you are also monitoring your calorie and nutrition targets alongside your injections, the calorie calculator for GLP-1 users is a useful companion resource.

Log Every Dose and Never Lose Track with GLP Trackr
Knowing your click count is only half the picture — the other half is having a reliable record of every injection you have done. GLP Trackr's dose and injection logging feature lets you record each shot the moment you do it: the date, time, dose strength, and injection site all in one place. Over a weekly injection schedule, that log quickly becomes a genuinely useful reference — especially if you ever feel unsure whether you have already taken that week's dose.
The app also tracks injection-site rotation, recording which area of your body you used last and suggesting your next site — abdomen, thigh, or upper arm — so rotation becomes automatic rather than something to remember separately. Pair that with dose reminders and your weekly schedule is covered end to end.
If you want to connect your dose data to your wider progress — weight trends, energy levels, how you are feeling — GLP Trackr brings all of that together in one dashboard. The weight reduction tracking tools and the full GLP-1 calculator hub are good places to explore how the different tracking features work together.
GLP Trackr is a tracking and journaling app, not a medical service. Any questions about your injection technique, dose, or pen device should be directed to your prescriber, pharmacist, or the patient information leaflet for your specific pen — they are the right sources for guidance on your individual treatment.

Frequently asked questions.
The number of clicks varies by dose strength and pen design. Always check the patient information leaflet supplied with your specific Mounjaro pen, or ask your prescriber or pharmacist — they can confirm what a completed injection looks and sounds like for your device.
Yes, many Wegovy (semaglutide) users use the same click-counting approach to confirm a complete injection. The exact number of clicks depends on the dose stage and pen type, so the patient information leaflet for your Wegovy pen is the definitive reference.
Removing the pen early can mean the full dose was not delivered. If you are unsure whether your injection was complete, contact your prescriber or pharmacist before taking any action — do not attempt to re-dose without their guidance.
GLP Trackr logs the date, time, dose strength, and injection site that you record after each injection. It is a personal log, not a clinical device — confirming injection technique should always involve your prescriber, pharmacist, or the leaflet for your pen.
Your prescriber or doctor decides your dose and any adjustments to it, based on your individual circumstances. Dose decisions should never be made independently — always follow the guidance of the clinician who prescribed your treatment.
