Always make sure to read the user instructions and the Patient Information Leaflet that comes with the device.

How do Mounjaro injections work?

Mounjaro injections work by mimicking two hormones your body naturally makes: GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). These hormones help control blood sugar levels and reduce hunger.

How Mounjaro works with your body

Mounjaro works with your body to help you lose weight. It’s most effective when used alongside a balanced, healthy diet and increased physical activity or exercise.

• Helps your pancreas make insulin: After you eat, Mounjaro tells the pancreas to release more insulin, a hormone that lowers blood sugar. Improving how your body uses insulin stops it from storing excess sugar as fat.
• Lowers the amount of sugar your liver makes: When your liver isn’t releasing sugar into the blood for energy, your body has to rely on fat stores for energy. This process, where the body breaks down its fat cells, is called lipolysis and leads to weight loss.
• Makes you feel full: Mounjaro works on the part of the brain that controls hunger, helping you feel full sooner and reducing how much you eat.
• Slows digestion: Mounjaro makes food move more slowly through the stomach, which helps prevent big spikes in blood sugar after meals and keeps you feeling full.

Understand who can use Mounjaro

Mounjaro is a prescription-only medication licenced in the UK for weight loss. This means there are guidelines on who it’s suitable for, based on a range of health factors and likelihood of successful treatment results.

It might be a suitable treatment for you if you meet the below initial eligibility criteria:

Possible Mounjaro weight loss results

Studies have shown a possible weight loss of up to 22.5% over 72 weeks. Mounjaro is a long-term weight loss treatment and not just a short-term option, you should start to see weight loss within the first 4-6 weeks.

Weight loss examples

One medical trial (there have been five so far) involved 2,539 people using either no Mounjaro, 5mg, 10mg or 15mg Mounjaro once a week for 72 weeks (just over 1 year and 4 months).

Everyone using Tirzepatide (Mounjaro) on the trial started with 2.5mg once weekly for the first four weeks. During this time, they lost around 3% of their starting body weight.

Tirzepatide users on the trial went up to 5mg once weekly for the next four weeks (weeks 5-8). During this time, users reached an average of 5-6% weight loss.

For weeks 9-12, some people stayed on 5mg of Mounjaro, and some moved up to 7.5mg weekly. Most people lost around 8% of their starting weight by week 12, regardless of whether they were on 5mg or 7.5mg.

Remember, studies show an example of what’s possible, but every weight loss journey is unique.
