What Is 1 mg Wegovy Equivalent to in Mounjaro Terms?

Wegovy (semaglutide) and Mounjaro (tirzepatide) are distinct medicines with different mechanisms of action, and their dose scales reflect that difference rather than representing a shared unit of effect.

Different drugs, different scales

Wegovy is a GLP-1 receptor agonist. Its commonly referenced dose strengths run from 0.25 mg through to 2.4 mg, with the 0.5 mg and 1 mg steps sitting mid-titration, and the 2.4 mg dose representing the maintenance level for many people. Mounjaro is a dual GIP and GLP-1 receptor agonist — it acts on two pathways rather than one. Its dose strengths run from 2.5 mg up to 15 mg. The numbers look very different simply because tirzepatide is measured and dosed differently, not because higher numbers mean stronger effects in any comparable sense.

What this means for the commonly asked comparisons

People often search for equivalences such as what 0.5 mg Wegovy maps to in Mounjaro terms, what 1 mg Wegovy compares to, or what 2.4 mg Wegovy — the highest maintenance dose — might correspond to on the Mounjaro scale. Because the medicines work differently, no published conversion table exists, and any figure circulating online is not a reliable clinical guide. Your prescriber or doctor is the right person to discuss how doses on one medicine relate to your experience and what an appropriate starting point would be if a switch were ever considered.

Titration is prescriber-led for both medicines

Both Wegovy and Mounjaro are typically started at a low dose and adjusted gradually over time — a process guided entirely by the prescriber based on how you are responding and tolerating the medicine. For context on how Mounjaro doses are structured, see our page on Mounjaro dosing and titration. For a fuller informational look at how the two medicines compare across their dose ranges, the pages on how 2.4 mg Wegovy relates to Mounjaro and 1 mg Wegovy and Mounjaro dose context cover this in more detail. You may also find it useful to read about what Wegovy dose is sometimes discussed alongside 5 mg Mounjaro.

Any decision about switching between these medicines, adjusting a dose, or moving from one to the other is a clinical decision — not something to act on based on an online comparison. Always follow the guidance of your prescriber or doctor, who knows your full medical history.

Whether you are on Wegovy or Mounjaro, keeping an accurate record of every dose you take is one of the most practical things you can do to stay on top of your treatment — and to have a clear, useful conversation with your prescriber at your next appointment.

GLP Trackr's dose logging feature lets you record each injection with its date, time, and dose strength, so you always have a precise history of what you have taken and when. If you have ever been unsure whether you took a dose, or wanted to show your prescriber exactly how your schedule has looked over recent weeks, that log makes the conversation straightforward.

The app also supports dose reminders, so a weekly injection is never accidentally missed — particularly useful during titration periods when your dose strength may be changing. If you do miss a dose, the right step is to contact your prescriber or doctor for guidance; the app can help you log the gap so you have an accurate record to share with them rather than relying on memory.

GLP Trackr works for both Wegovy and Mounjaro users. Whatever stage of your journey you are at, having your dose history in one place means you go into every prescriber appointment informed. If you have questions about your current dose or how your titration is progressing, those decisions belong with your prescriber — GLP Trackr helps you bring the evidence to that conversation, not replace it.
