03 · NHS or private

NHS or private in Hampton

Mounjaro is available on the NHS, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition, and the primary-care rollout began in June 2025 with the highest-need groups first, initially BMI 40+ with four or more qualifying conditions⁴⁶. Full rollout is expected to take years, so many people who meet the licensed criteria choose regulated private treatment. Ask your GP about NHS eligibility first.

06 · Who can use it

Who can be prescribed Mounjaro

Mounjaro is licensed for weight management in adults with a BMI of 30 or above, or a BMI between 27 and 30 with at least one weight-related condition such as high blood pressure, high cholesterol, obstructive sleep apnoea, cardiovascular disease, prediabetes or type 2 diabetes. It must be used alongside a reduced-calorie diet and increased physical activity. A prescriber assesses your BMI, medical history and current medicines before deciding if it is suitable¹.

07 · Dose ladder

Dose ladder

Everyone starts on 2.5mg once a week. This dose is about letting your body adjust, not weight loss itself. After at least 4 weeks it rises to 5mg, then by 2.5mg steps at minimum 4-week intervals up to 15mg, depending on response and tolerance. Many people settle at 5mg, 10mg or 15mg; higher is not automatically better¹¹¹.

08 · Results and pace

How much weight and how quickly

In SURMOUNT-1 (2,539 adults), people on tirzepatide with diet and exercise lost on average 15% of body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, versus 3.1% with lifestyle changes alone. Individual results vary². For someone starting at 100 kg, 20.9% is about 21 kg.

Weight loss is gradual. The first weeks on 2.5mg are an adjustment phase and most measurable progress builds from 5mg onward, month by month. If you have lost less than 5% of starting weight after 6 months on the highest dose you can tolerate, your prescriber will discuss next steps. Think in months, not days.

09 · Avoiding fake pens

Avoiding fake pens

The MHRA has seized thousands of fake weight-loss pens in the UK, and some fakes contained insulin rather than tirzepatide, causing hospitalisations. If you are pregnant or trying to conceive, do not use Mounjaro: it must not be used during pregnancy and should be stopped at least one month before trying to conceive. Only buy from a pharmacy you can verify on the GPhC register, never social media, beauty salons or unverified websites⁷¹². A genuine pen carries a batch number and expiry date, and the solution is clear and colourless. See also weight loss injections prices and nearby areas such as Portsmouth and Rye.
