How a Mounjaro injection prescription works in the UK

Step 1: The clinical consultation, what actually happens

The process begins with a structured health questionnaire. You'll be asked about your current weight, height, relevant medical history, any medicines you take and your weight-management goals. This isn't a tick-box formality. The information goes directly to a GPhC-registered Independent Prescriber who reads through your answers personally and makes a clinical judgement about whether Mounjaro is appropriate for you.

At nume, that review happens the same day. If there are questions, a prescriber may follow up directly. You'll also go through photo-ID verification and, where required, live weight verification on video, steps that protect both you and the integrity of the prescription. Transfer patients, or anyone requesting a dose increase, provide evidence of their current treatment before the prescriber proceeds. It is thorough because it needs to be.

The clinical team operates under the same professional standards as any regulated UK pharmacy. According to NHS guidance on tirzepatide, treatment is only appropriate alongside a reduced-calorie diet and increased physical activity, so the consultation will touch on lifestyle context too.

Step 2: What the prescriber is assessing, eligibility in plain terms

Mounjaro's UK licence covers adults aged 18 and over. The BMI threshold is 30 or above for most people, or 27 or above if you have at least one weight-related condition, things like hypertension, dyslipidaemia, obstructive sleep apnoea or type 2 diabetes all count. For people from South Asian, Chinese, Middle Eastern, Black African or African-Caribbean backgrounds, UK guidance recognises that risk increases at lower BMI values, so thresholds may be set 2.5 kg/m² lower. You can check your BMI quickly using the NHS BMI calculator before your consultation.

Meeting a BMI threshold is a starting point, not a guarantee of approval. The prescriber considers the full picture: existing conditions, current medicines, contraindications and whether any aspect of your history warrants further discussion with your own GP. Mounjaro is not recommended during pregnancy, while breastfeeding, or if you are actively trying to conceive. It is also not licensed for under-18s. Certain conditions (a history of medullary thyroid carcinoma, MEN2 or previous pancreatitis, for example) require careful prescriber consideration.

Step 3: The prescription, dispensing and what happens next

If the prescriber determines that Mounjaro is clinically suitable, a prescription is issued and your treatment is dispensed directly from our GPhC-registered pharmacy (registration number 9012878, verifiable on the GPhC register). Medicines are sourced through the licensed UK supply chain from Eli Lilly's authorised distribution network, not grey-market imports.

Dispatch happens the same day your consultation is approved, provided it's before 12 pm on a weekday. DPD delivers the next working day in unbranded packaging. The starting strength for Mounjaro is 2.5 mg, the prescriber sets this, and titration is discussed as part of your ongoing care, not left to you to decide independently.

Aftercare matters here. Our prescribers are available seven days a week, and every repeat order is clinically re-reviewed before it is dispensed. There are no automatic renewals.

NHS prescriptions versus private: the honest comparison

It is worth knowing that Mounjaro is available on the NHS, but access is phased and currently restricted to people with high BMI scores and multiple weight-related conditions. NICE's guidance (TA1026, published December 2024) sets out which cohorts qualify and when. The rollout is still rolling out: as of summer 2026, the NHS is in the early stages of making tirzepatide available through GP practices, and waiting times vary considerably by area. Many people who are technically eligible face a long wait. You can read more about how the NHS Mounjaro injection route works and what the current phase means for your eligibility.

A private prescription through a regulated online pharmacy is an alternative for people who don't meet NHS criteria yet, or who'd rather not wait. Some patients also ask whether they can buy tirzepatide pills instead, and that page explains what oral formulations are currently available and how they compare to the injection. Our cost guide addresses what the market price range looks like and what drives the differences between providers. One thing worth saying plainly: for a prescription medicine, the cheapest listing answers the wrong question. Clinical safety, genuine supply chain and proper prescriber oversight are the measures that count.
