What Kind of Doctor Can Prescribe Mounjaro? (October 2026)

01 · Your options

NHS GP or private prescriber: which route?

Your NHS GP is the first route, but access depends on the phased rollout. Mounjaro is available on the NHS, and NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition. The primary-care rollout began in June 2025 with the highest-need groups first, initially BMI 40+ with four or more qualifying conditions.⁴⁶ Full rollout is expected to take years, which is why many people who meet the licensed criteria choose regulated private treatment rather than waiting.

If you are unsure where you stand, read whether your own doctor can prescribe it, or how to raise it with your GP.

02 · Private

Getting a private prescription

A private prescriber must be registered with the GPhC or another UK regulator, and it should be a clinician, not a scoring script. Payment is taken when you place the order; if the prescriber decides the treatment is not suitable, the order is refunded automatically in full. Read more about whether a private doctor can prescribe Mounjaro.

Ordering takes three steps: complete the free online consultation, wait for prescriber review, then receive free next-day tracked delivery, with same-day dispatch when ordered by 3pm. Your first 2.5mg pen costs £129.99 with code FIRST40 (standard price £169.99), and every later order is £25 off the standard price. Start your free consultation when ready.

03 · Licensed eligibility

Who Mounjaro is licensed for

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.¹ A prescriber will assess your BMI, medical history and current medicines before deciding whether it is suitable.¹¹

04 · What it is

What you would be prescribed

Mounjaro is the brand name for tirzepatide, a once-weekly injectable prescription medicine made by Eli Lilly. It is licensed in the UK for weight management in adults and for type 2 diabetes, and comes as a multi-dose KwikPen in six strengths: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg.¹

In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone. These are trial averages and individual results vary.²

05 · Other clinicians

What about other clinicians?

Not every healthcare professional prescribes it. Ask whether any doctor can prescribe Mounjaro, or whether dentists can prescribe it. For the weight-loss indication specifically, see whether your doctor can prescribe Mounjaro for weight loss. You can also browse all weight loss treatments or buy Mounjaro through our pharmacy, supplied via official LillyDirect supply.

Mounjaro is a prescription-only medicine, supplied only after an online consultation reviewed by a GPhC-registered prescriber. This page is information, not a substitute for medical advice.

06 · Serious side effects

Serious side effects: when to get help straight away

Serious side effects are uncommon but need urgent attention. Seek immediate medical help for: severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of skin/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing. If you take insulin or a sulfonylurea alongside Mounjaro, watch for low blood sugar (shakiness, sweating, confusion) — your prescriber may need to adjust those medicines.¹
