Mounjaro 2.5mg is the initiation dose. This dose will help your body become familiar with the medication and minimise any side effects before stepping up to a higher dose.
What is Mounjaro 2.5mg and how does it work?
Mounjaro 2.5mg contains the active ingredient tirzepatide and is the dose you will begin treatment on when starting this weight loss injection.
Mounjaro works by mimicking 2 natural hormones in the body, GLP-1 and GIP, and these help to:
Make you feel fuller, quicker for longer
Reduce your appetite
Slow down the emptying of your stomach
Improve your blood sugar control
The 2.5mg dose is the initiation dose and is not intended to be used long-term. This dose will help your body become familiar with the medication which will in turn reduce the chance of side effects.
Mounjaro is injected once a week, on the same day each week.

How many clicks is 2.5mg on a 5mg pen?
The Mounjaro pens are not designed to be used in this way.
You should not use clicks to measure your dose.
Mounjaro pens are designed to deliver the full prescribed dose only, and using clicks to give yourself a partial dose is not recommended. This could result in inaccurate dosing and could affect how well the medication works.
Always use the dose that has been prescribed by your clinician. If you need the 2.5mg starter dose, order the 2.5mg pen.

It may also be too early - losing weight gradually is recommended compared to rapid weight loss.
Weight loss can vary among individuals and depends on factors including:
