Tirzepatide (Mounjaro®) for weight management

It was announced on 23 June 2025 that people living with obesity will begin accessing tirzepatide (Mounjaro®) for weight loss purposes in primary care settings.

Weight management services are locally commissioned and funded at an Integrated Care Board (ICB) level, which means services will differ across each ICB. In mid Essex, the specialist weight management provider Second Nature is providing access to tirzepatide (Mounjaro®) through an outreach service. GP practices can refer patients to this service.

Patients who wish to access Mounjaro through specialist weight management services must meet the eligibility criteria for Mounjaro. Patients who currently pay for Mounjaro outside of the NHS (privately) and would like to request an NHS prescription will need to meet the eligibility criteria at the time of their NHS referral to the Tier 3 specialist weight management service.

Please note that acceptance onto the Tier 3 specialist weight management service does not guarantee access to Mounjaro. Access to this medication is prioritised for those facing the most significant health risks related to their weight: people living with obesity, in poor health with multiple obesity-related conditions.

Tirzepatide FAQs for mid Essex residents

The full qualifying clinical criteria is a BMI (Body Mass Index) of 40 or more, plus four or more of the following diagnosed health conditions:

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

Drug access must be accompanied by wraparound care, which includes support for people to make dietary changes and to increase physical activity. Services will not prescribe tirzepatide as a standalone treatment. Patients must fully participate with the wraparound support programme.

Tirzepatide (Mounjaro®) might not be considered clinically suitable for everyone, and not everyone who meets the eligibility criteria will want to use it to support their weight loss. Therefore, there are alternative weight management services available in mid Essex.

Patients can continue taking tirzepatide (Mounjaro®) if the NHS has prescribed it to manage their diabetes. If you have any questions, speak to a healthcare professional.

If patients are using tirzepatide (Mounjaro®) bought privately, they may be able to access the medication through an NHS prescription if they meet the NHS qualifying criteria. However, patients should not gain advantage over other patients waiting for NHS care and would join the end of any existing waiting list.

It is important to tell your GP if you are taking tirzepatide (Mounjaro®) if the NHS hasn’t prescribed it, as it may impact your health and other treatments you are having or may need.

In mid Essex, the specialist weight management provider Second Nature is providing access to tirzepatide (Mounjaro®) through an outreach service. GP practices can refer patients to this service.

There are currently no plans to make tirzepatide available on the NHS through pharmacies in mid Essex.
