Is Mounjaro the Same as Ozempic?

These medicines are frequently confused because they belong to the same broader class and share some effects — but the differences are clinically meaningful.

Active substances and mechanisms

• Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist. It acts on two separate appetite-regulating pathways simultaneously — GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1).
• Ozempic (semaglutide) is a GLP-1 receptor agonist only. It acts on the GLP-1 pathway and is licensed primarily for the management of type 2 diabetes in adults, though it is sometimes discussed in the context of weight.
• Wegovy (semaglutide) contains the same active substance as Ozempic — semaglutide — but is a different product, licensed specifically for chronic weight management, and supplied at a higher maximum dose (up to 2.4 mg weekly).

So is Wegovy the same as Ozempic?

Wegovy and Ozempic share the same active substance (semaglutide) and the same GLP-1 mechanism, but they are distinct licensed products with different approved indications and dose ranges. They are not interchangeable without prescriber guidance. You can read more in the dedicated page on how Wegovy and Ozempic compare.

Is Wegovy the same as Mounjaro?

No. Wegovy contains semaglutide (a GLP-1 agonist only), while Mounjaro contains tirzepatide (a dual GIP and GLP-1 agonist). They are different molecules with different mechanisms. For a detailed factual look at how these two weight-management medicines differ, see the page on Wegovy and Mounjaro compared. Which medicine is appropriate for any individual is a decision for their prescriber or doctor — not something to determine from a comparison article.

Shared characteristics worth knowing

Despite their differences, Mounjaro, Ozempic, and Wegovy do have things in common: all are prescription-only, once-weekly subcutaneous injections; all act at least partly through GLP-1 receptors; and all are associated with commonly reported gastrointestinal effects such as nausea, constipation, and reduced appetite. According to the electronic Medicines Compendium (eMC), the full prescribing information for each product is listed separately, reflecting that these are distinct medicines with distinct profiles.

Whichever of these medicines has been prescribed to you, keeping a clear record of your journey matters — and that is exactly where GLP Trackr helps.

The app's dose and injection logging lets you record every weekly shot: the date, dose strength, and injection site. Over time, the app builds a complete history of your treatment so you always know where you are in your schedule. If you have questions about your medicine that arise between appointments — like why certain effects are happening when — having a timestamped log to share makes those conversations with your prescriber far more productive. The doctor report feature pulls your tracked data into a clear summary you can bring to a consultation.

GLP Trackr supports users on both Mounjaro and Wegovy, so whichever medicine you have been prescribed, the tracking tools are built around your journey. You can also explore how your weight, mood, energy, and side effects move together over time using the app's insights — patterns that are easy to miss when you are logging nothing at all.

GLP Trackr provides tracking and general information only — it is not a substitute for advice from your prescriber or doctor. If you have questions about which medicine is right for you, or any concerns about your current treatment, always speak with your healthcare professional.
