    Is Mounjaro® available in the UK?

    Mounjaro® has recently been approved as a weight loss treatment in the UK. It is now available on prescription at LloydsPharmacy Online Doctor.

    How does Mounjaro® work?

    The active ingredient, tirzepatide, activates two hormonal receptors (GIP and GLP-1). When these naturally occurring hormones are mimicked, your appetite is suppressed, blood sugar is better regulated and the rate at which food leaves the stomach is reduced. All of these actions result in weight loss.

    How Mounjaro Works

    How do you take Mounjaro®?

    You inject Mounjaro® once a week into your tummy, thigh or upper arm. Watch this video to find out more about how to inject yourself. Please note, alcohol swabs are not provided.

    Mounjaro® comes in several doses. Depending on where you are in your treatment journey, you will need to take a different dose.

    The starting dose is 2.5mg. This increases in increments of 2.5mg until you reach 15mg. The dose is gradually increased to make sure you can cope with any side effects. You will need to stay on each dose for four weeks before you increase it.

    If all goes to plan and you can tolerate the treatment, your dosing schedule will look like this:

    • Weeks 1-4: 2.5mg weekly
    • Weeks 5-8: 5mg weekly
    • Weeks 9-12: 7.5mg weekly
    • Weeks 13-16: 10mg weekly
    • Weeks 17-20: 12.5mg
    • Weeks 21 onwards: 15mg - Sign up to hear when available
