Mounjaro Dose: Understanding Your Schedule and Stages

Mounjaro is available in several dose strengths — commonly 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg. According to the electronic Medicines Compendium (eMC), treatment is generally started at the lowest dose and adjusted at intervals determined by your prescriber, based on how you are tolerating the medicine and progressing toward your goals. The 15 mg weekly injection is the highest available dose.

Titration is individual and prescriber-led

How quickly — or slowly — someone moves through the dose stages varies from person to person. Your prescriber sets the schedule that is right for your circumstances. Decisions about increasing or reducing your Mounjaro dose, including whether and when to go up or come down, are theirs to make in partnership with you. It would never be appropriate to adjust your own dose without their involvement.

Questions people commonly have about dose

• Lowest dose: The starting dose is typically 2.5 mg once weekly. It is an introductory dose, not a therapeutic target in itself.
• Maximum dose: The maximum Mounjaro dose is 15 mg once weekly. Not everyone will reach this stage; your prescriber will guide how far your titration goes.
• Reducing your dose: Some people find a lower dose suits them better — for example, if side effects are difficult at a higher stage. Whether you can or should reduce your dose is a conversation for your prescriber, not a self-managed decision.
• Dose in ml or clicks: Each Mounjaro KwikPen delivers a fixed, pre-set dose — you do not measure ml or count clicks yourself. Refer to the patient information leaflet that came with your pen, or ask your prescriber or pharmacist, for device-specific guidance.
• Splitting a dose: Splitting or modifying a Mounjaro dose is not part of the licensed prescribing instructions. If you have questions about this, speak with your prescriber before making any changes.

For a visual overview of how the stages progress, see the Mounjaro dose chart. If you want to understand how dosing relates to weight loss specifically, the page on Mounjaro dose for weight loss covers the general evidence base. And if you have missed an injection, read the guidance on what to do after a missed Mounjaro dose — and discuss it with your prescriber promptly.

Staying on top of a weekly injection schedule is easier when every dose is logged. GLP Trackr's dose-logging feature lets you record each injection — the dose strength, date, and time — so you always have an accurate record of where you are in your schedule. Over time, this builds a clear history you can share with your prescriber at appointments.

The app also sends gentle dose reminders so a weekly injection is never accidentally forgotten. Missing a dose unintentionally can disrupt your schedule; a simple notification removes that risk. You can also log a missed dose directly in the app, with a note to discuss with your prescriber at your next contact.

For anyone on the 5 mg stage, the Mounjaro 5 mg hub covers what to expect at that point in your titration, and GLP Trackr tracks your progress across every stage as your dose evolves.

Important: Any decision about your Mounjaro dose — including whether to increase, hold, or reduce it — should always be made with your prescriber, never on your own. GLP Trackr helps you record your journey accurately so those conversations are informed; it is not a substitute for clinical guidance. If you experience side effects that are severe, persistent, or worrying at any dose stage, contact your healthcare professional promptly. Any side effects can also be reported to your national pharmacovigilance scheme (such as the UK's Yellow Card scheme) as well as to your healthcare team.

Never lose track of your weekly schedule again — log every dose, set reminders, and build a record you can bring to your prescriber. Download GLP Trackr free on the App Store or Google Play and start your 7-day trial today.
