Mounjaro Stickers on the KwikPen: What Every User Should Know

Step 1, Find the sticker sheet before your first injection

When your Mounjaro pen arrives, the sticker sheet sits inside the box alongside the pen and the Patient Information Leaflet. Take a moment before your first injection to locate it. Each sheet holds four stickers, one per dose in that four-week pen. The sticker colour matches the pen's strength: the 2.5 mg pen has its own colour, the 5 mg another, and so on up the dose ladder. You can confirm the colour coding by checking the Mounjaro SmPC on the electronic Medicines Compendium, which lists packaging details for every strength. Getting familiar with this before injection day means you are not hunting for paper while trying to keep to your weekly routine.

If you have transferred to nume from another provider and your sticker sheets are incomplete, a simple dated notebook entry works just as well, the sticker is a prompt, not a requirement.

Step 2, Peel and log immediately after each injection

The most reliable habit is to peel the sticker off the sheet the moment you have completed your injection and press it straight into a diary, a small notebook, or a paper calendar. Do it before you recap the used needle or put the pen back in the fridge. That sequence matters: the injection triggers the action, the action triggers the log. One practical check you can do in under a minute, glance at your log sheet and count the stickers. Four stickers for a completed pen, three for one remaining dose, and so on. It immediately tells you where you are in your pen without opening the fridge.

For people who prefer a digital record, photographing the sticker on the dated calendar page before closing the book works equally well. The NHS tirzepatide guidance recommends injecting on the same day each week; a dated sticker log makes it easy to confirm you have done exactly that, especially across bank holidays or travel.

Step 3, Use the log when speaking to your prescriber or aftercare team

Your sticker log becomes genuinely useful at clinical review. A prescriber considering whether to increase your dose will want to know your injection history: how many doses you have taken at the current strength, whether any were delayed, and whether side effects clustered around specific injections. A dated record answers all of those questions in seconds. People using Mounjaro for weight management sometimes find that a gap in their log coincides with a week when nausea was difficult, that kind of pattern is worth raising. Our aftercare team is available seven days a week through the contact page if you have questions between formal reviews.

If you are exploring how lifestyle choices interact with treatment, Mounjaro users share experiences that touch on everything from side effect timing to social situations, including questions about alcohol that frequently come up at dose reviews. If your log shows slower progress than you expected, our guide on how to lose weight quicker on Mounjaro covers the dietary and lifestyle adjustments that can make a meaningful difference alongside your injections. Equally, if you are thinking about whether your social habits might be affected, our page on whether you get drunk quicker on Mounjaro covers what the evidence and user experience suggest. The sticker log sits at the centre of all of that: a small habit with disproportionate clinical value.

Step 4, Store and dispose correctly, then start fresh with the next pen

Once a pen is finished, the used sticker sheet can be kept with your disposal record or simply filed. Sharps (used needles) go into a sharps container and are disposed of through your local pharmacy or council collection service, never in household waste. The empty pen itself follows the same route. Starting a new pen at a higher strength means a new sticker colour: take a second to confirm the colour matches what your prescriber has authorised before you inject. If the sticker colour looks unfamiliar, compare it to the SmPC or call the pharmacy before proceeding.

Sticker sheets are not replaceable through nume as a standalone item, they are part of the licensed packaging. If your sheet is missing when your pen arrives, contact us through our support team immediately. Separately, for background on the clinical framework behind tirzepatide, the tirzepatide overview covers how the medicine works and what the evidence shows. If you take heart or blood pressure medication, our page on Mounjaro and beta blockers explains what the current guidance says and what to discuss with your prescriber. Mounjaro is a Black Triangle medicine under MHRA additional monitoring; reporting any suspected side effects through the Yellow Card scheme supports ongoing safety data for everyone using it.
