How Mounjaro Dosing Works for Weight Loss
Mounjaro is a once-weekly injectable medicine containing tirzepatide, a dual GIP and GLP-1 receptor agonist. It is prescribed as a prescription-only medicine, and the dose is not something you choose yourself — it is titrated gradually by your prescriber to balance effectiveness with tolerability.
Typical dose strengths
Tirzepatide is available in several strengths — commonly 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. Treatment typically begins at the lowest strength, giving the body time to adjust before any increase is considered. For full prescribing information, the electronic Medicines Compendium (eMC) holds the approved Summary of Product Characteristics.
Why titration matters
Increasing too quickly can intensify gastrointestinal side effects such as nausea, vomiting, or diarrhoea. Staying at a dose that is working well for you — even if it is not the highest available — is often entirely appropriate. Your prescriber weighs your results and how you are feeling before recommending any adjustment. As explained on our page about how Mounjaro dosing is structured, the schedule is designed to be gradual and individualised.
No dose is universally "best"
Some people achieve their weight-loss goals at a mid-range strength; others may eventually move to a higher dose. The dose that works best is the one your prescriber has tailored to your circumstances — not the highest one available. If you have questions about whether your current dose is right for you, that conversation belongs with your prescriber or doctor. For more context on what dose of Mounjaro is used for weight loss, and what the titration journey typically looks like, see our dedicated guide.
If you are just getting started, our overview of what to expect from your first dose of Mounjaro covers the early stages of treatment in more detail.

Tracking Your Mounjaro Doses with GLP Trackr
Because Mounjaro is taken once weekly and typically changes strength over time, keeping an accurate dose log is genuinely useful — both for your own peace of mind and for conversations with your prescriber.
GLP Trackr's dose-logging feature lets you record each injection as you take it: the date, time, and dose strength, all in one place. Over weeks and months, this builds a clear picture of your titration journey, so you always know exactly where you are in your schedule. The app also sends gentle reminders so a weekly dose is never forgotten — particularly helpful when life gets busy.
Beyond dose tracking, if you experience side effects at a particular strength, you can log those too. Having a record of how you felt at each stage — nausea levels, energy, appetite changes — gives you something concrete to bring to your next prescriber appointment rather than relying on memory. Our hub covering Mounjaro dosing and the titration journey brings together everything you need to stay informed at each stage.
Any decision about your dose — whether to increase, stay, or adjust — must be made with your prescriber. GLP Trackr helps you record your journey accurately so those conversations are as informed as possible; it is not a substitute for clinical guidance.

Frequently asked questions.
There is no universally best dose — the right strength is determined by your prescriber based on your individual response and tolerability. Tirzepatide is titrated gradually from a low starting dose, and the dose that suits you may differ from someone else's.
Mounjaro (tirzepatide) is commonly available in strengths of 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. Treatment typically starts at the lowest strength. For full details, refer to the product information leaflet or the electronic Medicines Compendium (eMC).
You can discuss your progress and how you are tolerating your current dose with your prescriber. Any decision to increase, maintain, or adjust the dose is theirs to make based on your full medical picture — never change your dose on your own.
What to do after a missed dose is a decision for your prescriber or the guidance in your patient information leaflet — do not double up without clinical advice. GLP Trackr lets you log a missed dose so you can discuss it accurately at your next appointment.
GLP Trackr lets you log each injection with the date, time, and dose strength, and sends weekly reminders so you never miss a dose. Over time, your log gives you and your prescriber a clear record of your titration journey and how you felt at each stage.
