Weight Loss Injections on the NHS (Mounjaro)

We know many of you are asking about Mounjaro (Tirzepatide), launching on the NHS from Monday 23rd June 2025.

It is important to understand GP practices, including ours, are not yet able to prescribe it and that there is strict eligibility criteria.

Please do not call at this time to request Mounjaro, or an appointment related to requesting weight loss injections.

Even when details of how GPs can provide Mounjaro have been agreed, we will need to arrange training and set up clinics, which will take time.

We want to help as many patients as we can, but are limited by the plans of the ICB based on NHS England requirements.

Please help us to help you – and please don’t make appointments about this right now.

 

Who will be eligible to get Mounjaro on the NHS?

Eligibility will be based on Body Mass Index (BMI) and the number, and type of other obesity related health conditions a person has.

To be prescribed Tirzepatide (Mounjaro®) people must have a BMI of 40 or more AND four or more of the following health conditions:

  • Hypertension
  • Dyslipidaemia
  • Obstructive sleep apnoea
  • Cardiovascular disease
  • Type 2 diabetes mellitus
 

Specialist Weight Management Service

At the moment, the only way to access Mounjaro on the NHS is through a specialist weight management service.

If you meet the eligibility criteria, you’ll need to book an appointment with your GP. They will assess your health and, if appropriate, refer you to the specialist service for further support and consideration of treatment.

This is to make sure the medication is prescribed safely and as part of a wider, personalised care plan.

The Specialist Weight Management Service offers a weight management programme for a period of 12-18 months that supports adults with severe and complex obesity to lose weight through a series of interventions including psychological approaches and dietary changes, with the involvement from a dietitian, psychologist, physiotherapist and consultant.

Important Information: Weight loss injection taken with Contraception and HRT

Important Information: GLP-1 Medications and Hormone Treatments

If you are taking GLP-1 receptor agonists (such as semaglutide, liraglutide, or others), it’s important to know how these medications might affect hormonal treatments, including contraception and hormone replacement therapy (HRT).

Oral Contraception

GLP-1 medications may reduce the absorption of oral contraceptives. This can lower their effectiveness and increase the risk of unplanned pregnancy.

What you should do:

Consider using a non-oral form of contraception (e.g., condoms, patch, injection, implant, or IUD), especially when starting or increasing the dose of a GLP-1 medicine.

Speak with your healthcare provider about the most suitable contraception option for you.

Oral Progesterone (Used in HRT)

GLP-1 medications may also affect the absorption of oral progesterone, which is commonly used as part of hormone replacement therapy (HRT).

What you should do:

If you are taking oral progesterone for HRT and start or increase a GLP-1 medication, your dose may need to be adjusted.

Do not change your medication on your own — always consult your doctor or menopause specialist.

If you have any questions or concerns regarding your contraception or HRT, please don’t hesitate to contact the practice.
