Mounjaro Sales Are Rising — Here's What That Means If You're Already on It

Sales figures for Mounjaro and Wegovy reflect the number of prescriptions being issued worldwide — not a recommendation to start, switch, or change treatment. Both are prescription-only medicines, meaning they can only be obtained through a qualified prescriber and a registered pharmacy. Any decision about which medicine is appropriate, and at what dose, belongs entirely with your prescriber or doctor.

Two different medicines, one growing category

Mounjaro contains tirzepatide, a dual GIP and GLP-1 receptor agonist, while Wegovy contains semaglutide, which acts on GLP-1 receptors. Both are administered as once-weekly injections and are started at a low dose, with adjustments made by the prescriber over time. For a factual, side-by-side look at how the two medicines differ, see our Mounjaro vs Wegovy informational comparison.

Why sales data appears in the news

Media coverage of Mounjaro and Wegovy sales figures is common, partly because both medicines carry a Black Triangle (▼) designation in the UK, meaning they are subject to additional monitoring. Reporting suspected side effects to your national scheme — such as the UK's Yellow Card scheme — and to your healthcare professional remains important regardless of how widely a medicine is used. Growing uptake doesn't alter the individual safety picture; if you experience anything severe, persistent, or worrying, contact your healthcare professional promptly.

Whatever is happening in the wider market, your own journey is individual — and staying consistent with your weekly injection schedule is one of the most practical things you can do while on treatment. That's where GLP Trackr is built to help.

The app's dose and injection logging lets you record every shot — date, dose strength, and injection site — so you always have a clear record of where you are in your schedule. Dose reminders mean a weekly injection is less likely to slip by unnoticed, and the injection-site rotation tracker suggests your next site automatically, helping you spread injections across abdomen, thigh, and upper arm without having to remember yourself.

As prescriptions for these medicines grow, so does the value of having your own data in one place. GLP Trackr's progress tracking and insights turn your logged doses, weight, and wellbeing check-ins into a clear picture you can bring to your prescriber appointments — far more useful than trying to recall the last few weeks from memory.

GLP Trackr is a companion app, not a medical service. It doesn't give dosing advice or replace the guidance of your prescriber or doctor — but it does make it easier to stay on top of your own journey and have informed conversations with the people who are clinically supporting you.

Ready to bring your weekly routine together in one place? GLP Trackr is available free on the App Store and Google Play, with a 7-day trial so you can explore every feature before committing.
