Mounjaro Dose Chart: All Six Doses and How the Pen Works
This is a dose reference, not medical advice. Follow your prescription and the instructions on your pen.
Mounjaro Dose Chart
| Dose | When it's typically used | What it's for |
|---|---|---|
| 2.5 mg | Weeks 1-4 | Starter dose, eases your gut in |
| 5 mg | Weeks 5-8 | First treatment dose |
| 7.5 mg | Weeks 9-12 | Step up if you need more |
| 10 mg | Weeks 13-16 | Common maintenance dose |
| 12.5 mg | Weeks 17-20 | Step up if needed |
| 15 mg | Week 21 onward | Maximum dose |
This is the standard on-label pace. Plenty of people move slower, hold at a dose that's working, or stop stepping up once blood sugar and appetite are where they want them. The chart is a map, not a deadline.
Why there's no click count
Mounjaro doesn't have a dose dial. Each pen is a single-use auto-injector preset to one strength, and the vials are single-dose too.
That's the difference from Ozempic, which is a dial pen you hear click as you select a dose. With Mounjaro, you get the right dose by using the right pen, not by counting anything. Press the pen against your skin, and it delivers the full dose on its own.
So "how many clicks is 10 mg of Mounjaro" doesn't really apply. You're holding a 10 mg pen, and it gives 10 mg.
Why the titration goes slow
The step-up isn't random. Tirzepatide hits two gut hormone receptors, GIP and GLP-1, and both slow your stomach down. That slowdown is a big part of why appetite drops, but it's also why the early weeks can bring nausea and constipation.
Starting at 2.5 mg and climbing gradually gives your gut time to adjust at each level. Jumping straight to a high dose is how people end up miserable and quitting.
The move most experienced users make: only step up when your current dose feels stable. There's no prize for reaching 15 mg fast.
Compounded tirzepatide is measured differently
If you're on compounded tirzepatide instead of the brand pen, you have a vial and an insulin syringe, so you measure in units, not pens.
How many units equals your dose depends on the concentration your pharmacy mixed. Same molecule as brand Mounjaro, different product: brand pens are FDA-approved and quality-controlled, compounded vials are not FDA-approved, so the concentration depends on the source. Our tirzepatide reconstitution calculator gives you the units for your exact vial, and the compounded semaglutide and tirzepatide guide covers the rest.
Track your dose and your response together
Where you are in the titration, when you last stepped up, how your side effects and blood sugar moved with each change: that's a lot to hold in your head across months.
Regimen puts your dose, your titration stage, and how you're responding on one timeline, and reminds you when your weekly shot is due. Track your Mounjaro doses in Regimen.
Frequently Asked Questions
What are all the Mounjaro doses?
Six weekly strengths: 2.5, 5, 7.5, 10, 12.5, and 15 mg. The 2.5 mg dose is a starter to ease side effects, and 5 mg and up are the treatment doses.
Does Mounjaro have clicks like Ozempic?
No. Mounjaro is a fixed-dose pen or vial, so there's no dial and nothing to count. Ozempic is the one with a clicking dial. With Mounjaro, the pen delivers the full preset dose on its own.
How long do you stay on each Mounjaro dose?
Usually about four weeks per step, but it's flexible. Many people hold longer at a dose that's working rather than climbing on schedule. Your prescriber sets the pace with you.
What happens if I miss a dose of Mounjaro?
If it's been four days (96 hours) or less since your scheduled day, take it when you remember. If more than four days have passed, skip it and take your next dose on your regular day. Don't take two doses within three days of each other.
Can you stay on a lower Mounjaro dose?
Yes. If a lower dose is controlling your blood sugar and appetite, there's no rule that you have to reach 15 mg. The highest dose is a ceiling, not a goal.
What app tracks Mounjaro doses?
Regimen tracks your dose, titration stage, and side effects on one timeline and reminds you when your shot is due.
