Mounjaro Dose Schedule: Complete Month-by-Month Guide

The use of Mounjaro should be supervised by a qualified clinician who will monitor your response to treatment and any side effects.

In some circumstances patients may not be able to tolerate the higher doses of Mounjaro, but they can still experience benefit on a lower dose. In these situations patients may remain on a lower dose rather than stepping up to 12.5 mg or 15 mg.

Continuing below the licensed maximum can be appropriate under supervision when the balance of benefit, side effects, and individual goals supports it. Your clinician can explain what applies in your case.

It is important to actively engage with your treatment plan when using Mounjaro. The medicine is taken once weekly, with dose changes guided by your prescriber, typically in four-week intervals from 2.5 mg towards a maintenance dose up to 15 mg when suitable.

Attend follow-up consultations when invited, report persistent side effects early, and follow the missed-dose guidance in your patient information leaflet (generally if you miss a dose, you can take it within four days; otherwise skip and resume on your usual day).

A well managed plan is essential for long-term success. PrivateDoc recommends using a single coordinated provider for your Mounjaro treatment as part of overall weight management.

You must not use Mounjaro together with Wegovy, another GLP-1 weekly injection, or Saxenda (daily liraglutide). Only one weight loss injectable medicine should be used at any time.

When changing between medicines, prescribers use a washout gap and select a starting dose that reflects what you were on before. This is individual; do not attempt to self-switch.

For context on moving between injectable weight loss medicines, you may find it helpful to read staying on Mounjaro or switching to Wegovy and what happens when you switch from Mounjaro to Wegovy. Any switch to or from Mounjaro must be planned with your prescriber.
