Tirzepatide (also called Mounjaro^®) is a weight loss medicine that makes you feel fuller for longer and therefore less hungry. It comes in the form of an injection which you inject yourself, once a week.

From 23 March 2025, you may be prescribed tirzepatide (Mounjaro^®) to manage your weight only if it is prescribed by a specialist weight management service, where a healthcare professional feels it is the right treatment for you. In specialist weight management services, there are various healthcare professionals, such as dieticians and psychologists, who can help support you.

There has been a phased approach to service rollout within primary care settings (for example, GP practices), and initially tirzepatide (Mounjaro®) will only be available on the NHS to those with the highest clinical need. At first, people living with obesity who have been diagnosed with 4 of the weight-related health problems listed above and a BMI of 40 or more (adjusted for ethnicity) are eligible to access tirzepatide (Mounjaro®) through primary care settings.

Check with your local integrated care board to check your eligibility for an assessment of whether tirzepatide (Mounjaro^®) is the right treatment for you.  Additionally, please read this article from NHS England regarding eligibility.
