Brand Names vs Generic Names: What the Difference Means for You
A brand name is the commercial name a manufacturer gives to a medicine — Mounjaro and Wegovy are both brand names. The generic name, by contrast, identifies the active substance itself, regardless of who makes it or what it's called on the packaging.
Mounjaro: the generic name is tirzepatide
Tirzepatide is a dual GIP and GLP-1 receptor agonist. It works on two appetite-regulating pathways in the body, which is why it is sometimes described differently from older GLP-1 medicines. When you see "tirzepatide" on your prescription or in clinical information, it is referring to exactly the same medicine as Mounjaro. You can read more about how the medicine works and what to expect on our Mounjaro information hub.
Wegovy: the generic name is semaglutide
Semaglutide is a GLP-1 receptor agonist. Like tirzepatide, semaglutide mimics a naturally occurring hormone involved in appetite regulation and feelings of fullness. Wegovy is the brand name used specifically for the higher-dose semaglutide formulation approved for weight management. Our Wegovy overview page covers the key facts about that medicine in more detail.
Does a generic version of Mounjaro or Wegovy exist?
As of the time of writing, Mounjaro and Wegovy are both still under patent protection in most countries, meaning there is no approved generic equivalent on the market. "Generic Mounjaro" or "generic Wegovy" are not currently available as licensed medicines — if you see those terms used commercially, it is worth approaching them with caution and speaking to your prescriber or doctor before drawing any conclusions.
The medicines also go by other names in different contexts — for instance, tirzepatide is marketed under a different brand name for type 2 diabetes management. If you want to explore the various names and formulations used for Mounjaro, our page on other names for Mounjaro goes into more detail.

Keeping Track of Your Medication in GLP Trackr
Knowing whether your prescription says tirzepatide or Mounjaro, semaglutide or Wegovy, it all refers to the same medicine — and GLP Trackr supports both. The app's dose logging feature lets you record each injection with the exact dose strength, date, and time, so you always have a clear, accurate record of your treatment history regardless of what name appears on your packaging.
Over time, that log becomes genuinely useful: you can see your full injection history at a glance, spot any gaps, and bring a clear summary to your next prescriber appointment using the app's doctor report feature. If you ever need to describe your treatment to a new healthcare professional, having a precise record — dose by dose — removes any guesswork.
GLP Trackr also tracks injection site rotation, logging which site you used each time and suggesting the next one, which is helpful whether you're on tirzepatide or semaglutide.
Always follow the guidance your prescriber or doctor has given you about your specific medicine and dose. GLP Trackr is a tracking companion — it records your journey, but any questions about your prescription belong with the clinician who issued it.
