Mounjaro treatment follows a prescriber-controlled ladder: it starts low and steps up gradually, because the gradual climb is how the common gastrointestinal side effects are managed. The ladder below is the licensed schedule from the summary of product characteristics; your prescriber decides every step.
The licensed ladder
| Dose | When | Role |
|---|---|---|
| 2.5mg | Starting dose, weeks 1-4 | A treatment-initiation dose, not intended for long-term maintenance |
| 5mg | From week 5, after at least 4 weeks on 2.5mg | A licensed maintenance dose |
| 7.5mg | After at least 4 weeks on 5mg, if needed | A transitional titration step |
| 10mg | After at least 4 weeks on 7.5mg, if needed | A licensed maintenance dose |
| 12.5mg | After at least 4 weeks on 10mg, if needed | A transitional titration step |
| 15mg | After at least 4 weeks on 12.5mg, if needed | The maximum dose, also a maintenance dose |
Increases are made in 2.5mg increments with a minimum of four weeks at each step, and only if the prescriber judges the current dose tolerated and a higher one warranted. Not everyone climbs to 15mg: 5mg and 10mg are licensed maintenance doses, and staying at the dose that works is normal practice, not a compromise. Never increase your own dose or skip steps; if doses are missed, follow the patient information leaflet and ask your prescriber rather than doubling up.

Frequently asked questions
Can I skip steps on the Mounjaro ladder?
No. The minimum time at each step is part of the licence and exists to manage side effects. Dose changes are prescriber decisions; never increase your own dose, and if you miss doses follow the patient information leaflet rather than doubling up.
Do I have to reach the top Mounjaro dose?
No. The right dose is the one that works and is tolerated, decided with your prescriber. Staying at an intermediate dose is normal practice, and it also changes what treatment costs: the table above shows today's lowest price at every dose.
What does each Mounjaro dose cost?
The table above shows the lowest current UK online price per dose, first month and ongoing, re-checked every 12 hours, with links to compare every provider at that dose. The true cost guide shows multi-month totals including the step-up.
