How the Mounjaro Dose Stages Generally Work
According to prescribing information published on the electronic Medicines Compendium (eMC), tirzepatide is usually initiated at 2.5 mg once weekly. After a period typically lasting around four weeks, your prescriber may consider moving to the next strength — though the exact timing and whether an increase happens at all is always their call, not something to self-manage.
The six dose strengths at a glance
- 2.5 mg — starting dose; allows the body to adjust
- 5 mg — first maintenance strength, reached after initial titration
- 7.5 mg — next step, if your prescriber decides an increase is appropriate
- 10 mg — mid-range maintenance dose
- 12.5 mg — higher maintenance dose
- 15 mg — maximum dose; only reached if lower doses are tolerated and your prescriber advises it
It is worth knowing that not everyone reaches the higher dose strengths. Many people remain on an intermediate dose throughout their treatment — what matters is what is right for you individually, and that is a conversation to have with your prescriber.
A note on "dose splitting"
You may have come across the phrase "Mounjaro dose splitting" — the idea of dividing a dose across more than one injection. This is not a standard or approved approach and is not something to attempt without explicit guidance from your prescriber. If you have questions about how your dose is structured, raise them at your next appointment.
For a closer look at how individual doses are used in practice, see the guide to Mounjaro dosing. If you are also interested in how a similar titration chart works for semaglutide, the Wegovy dose chart covers the equivalent stages.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.

Tracking Your Dose Stage with GLP Trackr
Knowing which dose stage you are on — and being able to show that record clearly — is one of the most practical things you can do to support your treatment. GLP Trackr's dose logging feature lets you record every injection: the strength, date, and time, all in one place. Over weeks and months, that builds into a clear, chronological history of your titration journey.
A couple of features make this especially useful for dosing:
- Dose reminders — a gentle weekly alert means you are far less likely to lose track of your injection day, which matters when your schedule is tied to a specific titration stage.
- Doctor report — when you have an appointment coming up, the app can generate a summary of your logged doses and progress, giving your prescriber a clear picture of where you have been and how you have responded at each stage.
If you have missed a dose and are unsure what to do, please do not make that decision alone — what to do after a missed Mounjaro dose explains the general principles, and your prescriber or the patient information leaflet in your pen pack should always be your first reference. The app can log a missed dose so you have an accurate record to discuss with them.
For a broader overview of managing your Mounjaro treatment, the Mounjaro treatment hub brings together the full picture in one place.
Any decision about your dose — including whether to move up, stay at your current strength, or pause — belongs with your prescriber. GLP Trackr helps you keep an accurate record to support those conversations; it does not replace them.

Frequently asked questions.
Mounjaro (tirzepatide) is available in six strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg, each given as a once-weekly injection. The starting dose is typically 2.5 mg, with increases decided by your prescriber based on your individual response.
Dose increases are decided entirely by your prescriber, not on a fixed universal timetable. They consider how well you are tolerating the current dose and how you are responding to treatment. Never adjust your dose without their guidance.
Dose splitting refers to dividing a single Mounjaro dose across more than one injection. This is not a standard approved practice. If you have questions about your dose structure, speak with your prescriber rather than attempting to split doses independently.
Decisions about a missed dose belong with your prescriber or are covered in the patient information leaflet included with your pen. Do not double up or make changes to your schedule without guidance. You can log a missed dose in GLP Trackr to keep an accurate record for your next appointment.
GLP Trackr lets you log each injection with its dose strength, date, and time, building a clear titration history. Dose reminders help you stay on your weekly schedule, and the doctor report feature gives your prescriber a summary to review at appointments.
