Mounjaro® (tirzepatide)

Weekly injection (pre-filled pen). Prescription only.

About this treatment

Active ingredient: Tirzepatide.

The active ingredient in Mounjaro is tirzepatide. It mimics the effect of two of your natural hormones that help you feel full, which can mean you eat less.

It is used alongside a reduced-calorie diet and more physical activity.

How it's taken

Mounjaro is injected once a week with a pen, into your stomach, upper arm or thigh.

Strengths: 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg.

If you are new to Mounjaro, you usually start on 2.5 mg once a week for the first month. The dose may then be increased in steps of 2.5 mg a month. The clinician decides your dose.

If you are already taking it and want a higher or lower dose, you will need to provide evidence of your prescription.

Trial results

Average 22.5% weight loss over 72 weeks at 15 mg in people who took it as directed (SURMOUNT-1 trial). Individual results vary.
