Mounjaro titration planner
Build a step-by-step dose schedule — including gentle 0.5mg increments — and see the exact KwikPen clicks to dial at each stage. Many people titrate slowly to manage side effects.
Educational tool — not medical advice. This calculator is for general information only. Mounjaro (tirzepatide) is a prescription-only medicine. Always follow the dosing instructions given by your prescriber and the patient information leaflet, and never change your dose or use click-counting without professional guidance.

How Mounjaro titration works
Titration means starting Mounjaro (tirzepatide) at a low dose and increasing it gradually. The aim is to give your body time to adjust and to keep side effects — most commonly nausea, but also constipation, diarrhoea and fatigue — to a minimum. Going up too quickly is the most common reason people feel rough on Mounjaro.
Everyone starts at 2.5mg once a week. This is a non-therapeutic starting dose whose only job is to ease you in. After four weeks, the dose usually moves to 5mg, and from there it can be increased in 2.5mg steps — always with at least four weeks at each level — up to the maximum of 15mg once weekly.
The standard Mounjaro titration schedule
| Dose | Typical timing |
|---|---|
| 2.5mg | Weeks 1–4 (starting dose) |
| 5mg | Weeks 5–8 |
| 7.5mg | Weeks 9–12 |
| 10mg | Weeks 13–16 |
| 12.5mg | Weeks 17–20 |
| 15mg | Week 21+ (maximum dose) |
This is the typical pattern — your prescriber may move faster or slower based on how you respond. There is no obligation to reach 15mg; the right dose is the lowest one that works for you.
Titrating in smaller steps
The standard jumps are 2.5mg, but some people find even those increases hard to tolerate. By counting clicks you can step up more gently — for example moving from 2.5mg to 3mg to 3.5mg instead of straight to 5mg. The planner above lets you choose a 0.5mg or 1mg step and shows the clicks for each stage, so a single higher-strength pen can deliver several in-between doses. Always agree any non-standard schedule with your prescriber first.
Once you know your target dose, the clicks calculator shows the clicks and estimated drug levels, and the pen tracker helps you see how far each pen will stretch across your steps.
Frequently asked questions
- What is the standard Mounjaro titration schedule?
- The usual schedule starts at 2.5mg once a week for 4 weeks, then increases to 5mg. After that the dose can be raised by 2.5mg at a time, with at least 4 weeks at each step, up to a maximum of 15mg once weekly. 2.5mg is a starting dose to reduce side effects, not a maintenance dose.
- How long should I stay on each dose?
- At least 4 weeks before any increase. Many people stay longer on a dose if they are tolerating it well or still losing weight — there's no rush to reach 15mg. Your prescriber decides when to step up.
- Can I increase by smaller steps than 2.5mg?
- Some people use click-counting to step up more gently — for example by 0.5mg or 1mg — to reduce nausea and other side effects. This planner shows the clicks for any step size, but micro-dosing between the standard strengths should only be done on your prescriber's advice.
- What is the maximum Mounjaro dose?
- 15mg once a week is the maximum licensed dose. There is no 17.5mg or 20mg branded Mounjaro pen.
- How many clicks is each titration step?
- It depends on the pen. On a pen whose strength matches the dose you want, a full dose is 60 clicks. To dial a partial dose, clicks = (target dose ÷ pen strength) × 60 — e.g. 2.5mg from a 5mg pen is 30 clicks. The planner calculates this for every step.
