The Six Dose Strengths and How Titration Generally Works
Mounjaro is typically started at the lowest strength — 2.5 mg once weekly — before being reviewed and, where appropriate, increased by a prescriber. The full range of strengths available is:
- 2.5 mg — the standard starting dose
- 5 mg
- 7.5 mg
- 10 mg
- 12.5 mg
- 15 mg — the highest available strength
Each step up is intended to give the body time to adjust, which is one reason the titration schedule exists. How long someone stays at any given strength, and whether they reach the higher doses at all, is determined by their prescriber — not by a fixed timetable. For the full prescribing information, the electronic Medicines Compendium (eMC) holds the authorised product information for Mounjaro.
Mounjaro is a dual GIP and GLP-1 receptor agonist — a different mechanism from semaglutide-based medicines. If you are also curious about the dose strengths available for Wegovy, those follow a separate titration schedule.
Because Mounjaro carries a Black Triangle (▼) designation, any side effects experienced at any strength should be reported to your healthcare professional and to your national reporting scheme (such as the UK's Yellow Card scheme). You can read more about the potential risks associated with Mounjaro and what safety considerations to be aware of before discussing concerns with your prescriber.

Keeping Track of Your Doses With GLP Trackr
With six possible strengths and a weekly injection schedule, it is easy to lose clarity on where you are in your treatment — especially across a titration period that can span many months. The dose logging feature in GLP Trackr lets you record each injection with the exact strength and date, so you always have an accurate, timestamped history of what you have taken and when.
Alongside dose logging, the app's reminder feature helps make sure a weekly injection is never simply forgotten. And if something comes up — a side effect at a new strength, a question about timing — the app lets you log a note to bring to your next prescriber appointment, rather than trying to recall details weeks later.
Everything you log builds into a clear picture of your journey that you can share with your prescriber. That kind of record can be genuinely useful when discussing whether your current dose is right for you — though any decision about changing strength always belongs with them, never with an app.
For a broader overview of tracking your Mounjaro journey from the start, visit the Mounjaro companion guide.
GLP Trackr provides tracking tools and general information — it is not a substitute for your prescriber's guidance. If you have concerns about your dose or how you are responding at any strength, contact your healthcare professional.

The Most Advanced GLP-1 Brain Ever Built.
The first AI built exclusively for GLP-1 weight loss. Every insight, every meal plan, every prediction trained on one thing only: helping you get the most out of your medication.
Knows Your Cycle
GLPIQ tracks where you are in your injection cycle and adjusts everything around it: lighter meals on nausea days, higher protein when appetite returns, and smarter targets as your medication level shifts.
Predicts Before You Feel It
GLPIQ learns your personal side effect patterns over time. After a few cycles, it starts warning you the morning before a rough day — and adjusts your meal plan automatically.
Finds Your Golden Dose
GLPIQ analyses every dose you've been on: weight loss rate, side effects, food noise, mood, protein adherence and tells you which dose gave you the best results. No other app does this.

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. Treatment typically begins at 2.5 mg and is adjusted over time by a prescriber based on how an individual responds.
The appropriate dose and titration schedule is determined by your prescriber or doctor, based on your individual health, tolerability, and response to treatment. Dose decisions should never be made independently — always follow your prescriber's guidance.
Not necessarily for everyone. Prescribers adjust the dose to balance tolerability and response for each individual. Whether a higher strength is appropriate is a clinical decision — your prescriber is best placed to advise based on your progress and any side effects.
GLP Trackr lets you log each weekly injection with the dose strength and date, building a timestamped record you can refer to or share at prescriber appointments. The app's reminder feature also helps ensure a dose is not forgotten.
No. Mounjaro (tirzepatide) and Wegovy (semaglutide) are different medicines with different active substances and separate titration schedules. The strengths and dose steps differ between the two — your prescriber will guide you on the schedule relevant to your medicine.
