Mounjaro (Tirzepatide) is a licensed weight loss injection, self-administered once a week, now available in the UK. Mounjaro is a dual action medication which directly activates GIP and GLP-1.

GLP-1 helps users by making them feel a reduction in appetite, promoting a feeling of fullness and delaying stomach emptying by binding to GLP-1 receptors in the body. GIP helps to reduce fat accumulation, increase bone formation and glucagon production and also reduces stomach acid.

Mounjaro is available for adults over the age of 18 with a BMI over 30 or those who have a BMI of 27-30 with other weight related health problems.

Alongside a balanced diet and an exercise regime, it can help patients lose 21% weight on average over 18 months, according to clinical trials. Each Mounjaro pen has 4 fixed doses, one injection dose of 0.6ml taken weekly.
