Mounjaro Equivalent Dose to Wegovy: What You Should Know

Wegovy (semaglutide) is a GLP-1 receptor agonist, typically started at 0.25 mg once weekly and increased by a prescriber through stages up to 2.4 mg. Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist — it activates an additional receptor pathway (GIP) that Wegovy does not. Mounjaro is generally started at 2.5 mg once weekly and can be increased by a prescriber through stages up to 15 mg.

Because the two medicines work through partly different mechanisms, their dose numbers refer to different molecules with different potencies and receptor profiles. A 5 mg dose of tirzepatide is not equivalent to 5 mg of semaglutide in the way that, say, two different brands of the same molecule might be. Comparing them is more like comparing apples with pears — both are fruit, but they are not the same thing.

Some people who move between the two medicines want a rough clinical anchor — for example, understanding roughly where in the Mounjaro titration schedule corresponds to their previous Wegovy dose stage. This is a reasonable question, but the answer depends on individual factors including how you responded to each medicine, your prescriber's assessment, and the clinical context of any switch. There is no universally agreed conversion table, and any such comparison should be treated as a rough frame rather than a precise guide.

For a closer look at how specific dose stages are discussed, the pages on how Wegovy 2.4 mg relates to Mounjaro doses, what 5 mg Mounjaro corresponds to on Wegovy, and what 1 mg Wegovy means in Mounjaro terms explore these comparisons in more detail. The broader context of the Mounjaro dosing journey is covered in the Mounjaro 5 mg guide.

It is also worth noting that Ozempic (also semaglutide, but licensed for type 2 diabetes management) uses the same active substance as Wegovy. Dose comparisons between Ozempic and Mounjaro carry the same caveats: the milligram numbers refer to very different molecules, and equivalence is a clinical question, not a calculation.

Whichever medicine you are prescribed — and at whatever stage — keeping an accurate record of every dose is one of the most practical things you can do to support your own care.

GLP Trackr's dose logging feature lets you record each injection with its exact dose strength, date, and time. If your prescriber adjusts your dose, you can update your log immediately, giving you a clear timeline of your treatment history. This is particularly useful if you are transitioning between dose stages or if your healthcare team ever needs a summary of where you have been in your titration schedule.

Alongside dose logging, the app's dose reminders help you stay on your weekly schedule without having to rely on memory — a genuinely helpful feature when your dose stage changes and the new routine is not yet automatic. You can also use the doctor report feature to pull together a clear summary of your logged doses and progress, making prescriber appointments more productive.

Any decision about your dose — whether to stay at your current stage, move up, or make any other change — should always be made with your prescriber. GLP Trackr helps you record what you are taking so you can discuss it clearly; it does not replace clinical guidance.
