Mounjaro (tirzepatide) is a relatively new prescription medication used to support blood sugar control in adults with type 2 diabetes. It has also been approved to assist with weight loss in patients who are overweight or obese. As interest in Mounjaro grows across the UK, many people want to know how to get Mounjaro on the NHS, what the eligibility criteria are, and what options exist for those who cannot access it through the NHS.
This guide aims to provide up-to-date, clear information on obtaining Mounjaro through the NHS in the UK, including the current process, eligibility guidelines, costs, safety considerations, and private alternatives.
What is Mounjaro and How Does it Work?
Mounjaro contains the active ingredient tirzepatide, which belongs to a class of drugs called GLP-1 receptor agonists. It works by mimicking natural hormones that regulate blood sugar and appetite, helping patients to feel full longer, reduce calorie intake, and manage blood glucose levels more effectively.
Mounjaro is administered as a once-weekly injection using a pre-filled pen device. It is licensed for:
- Treatment of type 2 diabetes to improve glycaemic control.
- Supporting weight loss in patients with obesity or overweight, often alongside lifestyle changes.
Is Mounjaro Available on the NHS for Weight Loss?
As of 2025, Mounjaro is not widely available on the NHS for weight loss. While it is licensed for this purpose, NHS England has not issued a routine commissioning policy that broadly funds Mounjaro for obesity management. Access is typically limited to specialist services and is subject to strict eligibility criteria and regional variation.
NHS Weight Loss Medication Landscape
Other GLP-1 receptor agonists like semaglutide (Wegovy) have clearer NHS pathways, although availability still depends on local clinical commissioning groups (CCGs). The NHS continues to evaluate newer treatments for obesity to ensure clinical effectiveness and cost-effectiveness.
Who is Eligible for Mounjaro on the NHS?
NHS eligibility for Mounjaro may include patients who:
- Have a Body Mass Index (BMI) of 30 kg/m² or above, or a BMI of 27 kg/m² with associated health conditions such as type 2 diabetes, hypertension, or sleep apnoea.
- Have attempted and not achieved sufficient weight loss through lifestyle interventions such as diet and exercise.
- Are under the care of an NHS obesity specialist or endocrinologist authorised to prescribe GLP-1 receptor agonists.
- Are monitored regularly by healthcare professionals for efficacy and side effects.
How to Apply for Mounjaro on the NHS
- Consult Your GP: Begin by discussing your weight and related health conditions with your GP.
- Referral to Specialist Services: If appropriate, your GP may refer you to an NHS obesity clinic or endocrinology specialist.
- Assessment: The specialist will assess your eligibility based on BMI, health status, and previous treatment history.
- Prescription and Monitoring: If suitable, you may receive a prescription for Mounjaro with regular follow-up appointments.
Cost of Mounjaro on NHS Compared to Private Purchase
If you are prescribed Mounjaro through the NHS, the cost may be subsidised or free depending on your prescription charge status and local NHS policies.
For those who are not eligible or prefer private treatment:
- Mounjaro can be obtained privately via a UK-registered pharmacy with a private prescription.
- Prices for private purchase vary but typically range from £300 to £450 per monthly supply depending on dosage.
- Purchasing from registered pharmacies such as Ashcroft Pharmacy ensures safety and product authenticity.
Is Mounjaro Covered by Private Health Insurance in the UK?
Private health insurance coverage for weight loss medications like Mounjaro varies widely:
- Some policies may cover weight management treatments if medically necessary.
- Others explicitly exclude obesity medications.
- It is essential to check with your insurance provider regarding your specific policy and coverage details.
Safety Information and Side Effects
Mounjaro should only be used under medical supervision. Common side effects reported include:
- Nausea
- Diarrhoea
- Vomiting
- Decreased appetite
Most side effects are mild and tend to reduce over time. If side effects persist or worsen, contact your healthcare provider immediately.
Where to Get Mounjaro Safely in the UK
To ensure safety and compliance with UK medical regulations:
- Only obtain Mounjaro from UK-registered pharmacies that require a valid prescription.
- Avoid purchasing from unregulated online sources, which may sell counterfeit or unsafe products.
- Pharmacies such as Ashcroft Pharmacy provide genuine Mounjaro with expert guidance and support.
Summary
Mounjaro offers a new option for managing type 2 diabetes and supporting weight loss. However, NHS access for weight management is limited and subject to strict eligibility criteria. Private prescriptions are an alternative but should only be obtained through legitimate UK pharmacies.
