Mounjaro dosing schedule: the dose chart, and how you climb it
July 15, 2026 · 2 min read
The short answer
Mounjaro (tirzepatide) has six once-weekly doses, from 2.5 mg up to 15 mg. The 2.5 mg start is a starter dose, not a treatment dose, and you step up gradually so the gut can adapt and side effects stay manageable.
For type 2 diabetes, the target dose is whatever controls your blood sugar (and supports weight) while staying tolerable, not automatically the top. Your prescriber sets and adjusts it based on your results.
The Mounjaro dose chart
Mounjaro comes in six strengths, each a once-weekly injection: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. They are a ladder, not a menu. You start at the bottom and climb, giving your body time to adjust at each step.
| Dose | Role in the schedule |
|---|---|
| 2.5 mg | Starter dose (about 4 weeks); introduces the drug, not a treatment dose |
| 5 mg | First maintenance dose; many people get real effect here |
| 7.5 mg | Optional step up if more control is needed and it is tolerated |
| 10 mg | Common target dose for stronger effect |
| 12.5 mg | Optional step up toward the maximum |
| 15 mg | Maximum dose |
Why you start at 2.5 mg
The 2.5 mg dose is a starter, meant to introduce the medication gently rather than to control blood sugar or drive weight loss on its own. Starting low is how the class keeps nausea, diarrhea, and the other gut effects manageable, because the slowed stomach that causes them is easier to adapt to in small increments. Most people hold each dose for about four weeks before stepping up. Our titration guide covers the rhythm across the class.
How the step-up works
The standard path moves 2.5, then 5, then, if needed and tolerated, up through 7.5, 10, 12.5, and 15 mg, roughly every four weeks. There is no benefit to rushing: prescribers often hold a dose longer or pause a step if side effects are rough, and a slower climb is usually better tolerated. The 5 mg dose is the first real maintenance dose, and many people get good results without reaching the top.
What is your target dose?
For type 2 diabetes, the goal is the dose that controls your blood sugar (and supports your weight) while staying comfortable, guided by your prescriber and your labs, not automatically 15 mg. Some people settle at 5 or 10 mg; others go higher. Because Mounjaro is the diabetes brand of tirzepatide, the dose ladder is identical to Zepbound; the difference is what the dose is being aimed at.
Tracking your climb
Logging your dose, side effects, blood sugar, and weight week by week turns the titration from guesswork into a record. It shows your prescriber how each step landed and when it is reasonable to move up, which is exactly what sets your right dose. DoseLog keeps it in one line.
Questions people ask
What is the Mounjaro dose chart?
Six once-weekly strengths forming a ladder: 2.5, 5, 7.5, 10, 12.5, and 15 mg. The 2.5 mg dose is a starter, not a treatment dose; 5 mg is the first maintenance dose. You step up about every four weeks as tolerated.
How quickly do you increase Mounjaro?
The standard schedule holds each dose about four weeks before stepping up, as tolerated. Prescribers often slow the climb or hold a dose longer if side effects are rough. There is no benefit to rushing to a higher dose.
What is the maximum dose of Mounjaro?
15 mg once weekly is the highest dose. Many people reach good blood-sugar and weight results at a lower maintenance dose (such as 5 or 10 mg); the top dose is not required for everyone.
Is the Mounjaro dose the same as Zepbound?
Yes, the dose ladder is identical (2.5 to 15 mg), because both are tirzepatide. Mounjaro is the type 2 diabetes brand and Zepbound the weight and sleep-apnea brand; the doses match, the approved use differs.
