Mounjaro Titration Schedule

Each rung of the Mounjaro ladder, taken from Dosage & Administration in its FDA label (DailyMed SetID d2d7da5d-ad07-4228-955f-cf7e355c8cc0). The schedule you actually follow is the one your prescriber writes; this is the reference behind it, not advice about your case.

Step	Dose	When
1	2.5 mg once weekly	Weeks 1–4 — a run-in dose, not one that controls blood sugar
2	5 mg once weekly	Once 4 weeks at 2.5 mg are behind you
3	Increase in 2.5 mg increments (7.5 / 10 / 12.5 / 15 mg)	4 weeks or more at the current dose, if blood sugar needs more

How to titrate safely

One rule governs the whole ladder: you only climb if you are tolerating where you already are, and you hold or slow down when side effects flare. Outrunning the label's schedule does not get you results sooner. What it reliably produces is more nausea and more of everything else the gut does in response.

If you miss a dose or can't tolerate a step

Missed a dose? How late is too late is not the same answer for every drug. Read GLP-1 missed-dose rules by drug for what Mounjaro specifically allows, before you double up or write the dose off.

Can't tolerate a dose increase? Holding at the current dose, or waiting longer before the next step, is something the label explicitly permits. What each step tends to bring is set out on the Mounjaro side effects page, then talk to your prescriber before changing your schedule.

Frequently Asked Questions

Mounjaro (tirzepatide) opens at 2.5 mg injected subcutaneously once weekly for 4 weeks — the initiation dose written into its FDA label, DailyMed SetID d2d7da5d-ad07-4228-955f-cf7e355c8cc0. It exists to let your body adjust, and as a rule it is not the dose that produces the full effect.

Steps come in 2.5 mg increments, and never sooner than 4 weeks at the current dose. Inject once a week at whatever hour suits, fed or fasted; you may move which weekday you use as long as 72 hours separate the two doses. What governs you is the schedule written on your own prescription. The ladder above is the label's escalation, not advice about your case.

Its FDA label caps Mounjaro at 15 mg once weekly, and puts maintenance at 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg injected subcutaneously once weekly.

Late-dose windows are drug-specific, so check the missed-dose guide rather than assuming. Where a step up brings side effects you cannot live with, the label permits holding at the current dose or dropping back to the previous one — but raise it with your prescriber rather than deciding on your own. The Mounjaro side-effects page sets out what each step tends to bring.
