GPs prescribing Mounjaro

Accessing tirzepatide (Mounjaro) for weight loss

Your general practice or hospital services will not be able to prescribe this medication to you for obesity until arrangements are in place.

Please do not contact your GP or hospital service for Mounjaro (tirzepatide) for weight management as they have been asked not to prescribe it at this time.

Mounjaro is the brand name for tirzepatide, a drug which has been licensed and approved by the National Institute for Health and Care Excellence (NICE) for managing overweight and obesity.

From Monday, 23 June, people living with obesity will be able to be prescribed tirzepatide (Mounjaro) for weight loss purposes in primary care settings.

This does not mean prescriptions will be provided immediately. It means primary care settings can begin discussions with patients about whether tirzepatide is the right option to improve their health through weight loss.

According to NICE’s calculations, as part of its Technical Appraisal for tirzepatide, 3.4million patients in England would potentially be eligible for the drug, however the NHS does not have the services or existing resources to manage this number of people.

Therefore, the drug will be phased in gradually through a special agreement between NICE and the NHS in England, to make sure primary care services aren’t overwhelmed and can manage the extra demand safely.

This means that access will be prioritised for those with the greatest clinical need, as they would benefit most from the treatment.

Access to the drug must also be accompanied by a behavioural support for obesity prescribing service which will include support for people to make dietary changes and to increase physical activity.

To be prescribed tirzepatide (Mounjaro) patients must have a BMI (Body Mass Index) of 40 plus and four or more of the following diagnosed health conditions:

• type 2 diabetes
• high blood pressure
• heart disease
• obstructive sleep apnoea
• abnormal blood fats (dyslipidaemia)

Both patient and clinician also have to agree it is the most appropriate option and the right treatment for them.

People with the highest health risks and who meet the clinical criteria will be prioritised.
