GLP-1 dose schedule planner
Pick your medicine and the date of your first dose. You'll see each label dose step as dates, where you are now, and you can add the steps to your calendar.
Example: Mounjaro starts at 2.5 mg for 4 weeks, then goes up by 2.5 mg at least every 4 weeks, up to 15 mg.
Each one has its own steps on the label.
The day of your first injection at the starting dose.

[02] How it works
Label steps, earliest dates
The planner lays out each step from the medicine's label, starting on your first dose. Each step shows its earliest start date, because the label says at least 4 weeks per step.
For the doses in mL and syringe units, see the tirzepatide and semaglutide dosage charts.
[03] Questions
Questions
When do I go up a dose on Mounjaro or Zepbound?
After at least 4 weeks on each dose. You start at 2.5 mg, then go up in 2.5 mg steps to a maximum of 15 mg. Your prescriber decides when, or whether, to go up.
When does Wegovy reach 2.4 mg?
From week 17 on the label schedule: 0.25 mg, 0.5 mg, 1 mg and 1.7 mg, each for 4 weeks, then 2.4 mg.
Can I stay on a dose longer than 4 weeks?
Yes. The labels say at least 4 weeks per step, and a step can last longer, for example if side effects need time to settle. That's a decision for your prescriber.
What does the calendar file do?
It adds one all-day reminder on the earliest start date of each step to the calendar on your phone or computer. It doesn't send anything to us.

Guides that go with this calculator
- Tirzepatide dosage chart: mg, mL and unitsPrescriptions say mg and syringes say units. This chart lines up each Mounjaro and Zepbound label dose with its mL and U-100 units.
- Semaglutide dosage chart: mg, mL and unitsPens give you a set dose in mg. If your semaglutide comes from a vial, each label dose also has to become mL and syringe units.
- Missed dose checkerTake it now or skip it, from your GLP-1 label's rule.
- Wegovy 7.2 mg: who it's for, how you step up, and what the trials showed7.2 mg is the highest Wegovy dose. You only get there after time on 2.4 mg, and the US and UK rules differ in a few places.
