How Much Does 10mg Mounjaro Cost in the UK?
The cost of 10mg Mounjaro varies significantly depending on whether you access it through the NHS or privately in the UK. On the NHS, Mounjaro is available through specialist weight management services, though availability and waiting times vary by region. Privately, 10mg Mounjaro typically costs between £180–£250 per month through GPhC-registered online pharmacies, depending on the provider. Since Mounjaro works as a dual GIP and GLP-1 receptor agonist—different from single-mechanism alternatives like Wegovy—pricing can reflect this.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Understanding Mounjaro Pricing in the UK
NHS pricing: Mounjaro is available on the NHS through tier 3 specialist weight management services for eligible adults. The medication itself is provided free, but you'll need a GP referral and specialist assessment. NHS access varies significantly by region and integrated care board (ICB)—some areas have long waiting lists, whilst others may not currently provide access. Contact your GP for referral details in your area.
Private pricing: Via private online prescribing, 10mg Mounjaro typically costs £180–£250 per month, though prices vary between providers. This cost includes the online clinical assessment, prescription issuance, and medication supply via a GPhC-registered pharmacy. Each KwikPen contains 4 weekly doses. Prices may be lower at higher doses or on subscription plans. Always confirm the exact cost and what's included before ordering.

What Affects Mounjaro Costs?
Several factors influence the total cost of Mounjaro treatment. Dose level is a key factor—lower starting doses like 2.5mg or 5mg may be cheaper than the 10mg or maximum 15mg dose. Some private providers offer tiered pricing. Treatment duration matters too; you'll typically need ongoing prescriptions, so budget for months rather than weeks. Eligibility for NHS access (BMI 30+, or 27+ with weight-related health conditions) removes cost entirely, but private assessment fees apply if accessing privately. Use our free BMI calculator to check your eligibility status, and our progress tracker to monitor results once treatment begins.
