Mounjaro 7.5mg Price UK: Compared Across Every Pharmacy

If you've stepped up from 5 mg, you're probably wondering what the Mounjaro 7.5mg price looks like across UK pharmacies — because the number just jumped. We track the live 7.5 mg price at every regulated online provider we cover, and as of 17 July 2026 it ranges from £204.99 to £299 for four weekly doses. That's a £94 gap for the exact same tirzepatide pen. Here's the honest maths, no invented figures.

Two things worth flagging before the table. First, 7.5 mg is a genuine treatment dose (unlike the 2.5 mg starter), so this is the price you may live with for months. Second, first-month promo codes almost always apply to the 2.5 mg starter box only — by the time you reach 7.5 mg you're paying full list price, so the ongoing number is what actually matters.

Mounjaro 7.5mg price UK: the July 2026 ranking

Here are the ten cheapest providers for the 7.5 mg pen, sorted by ongoing price for four weekly doses. All figures were last checked on 17 July 2026.

Prices last checked 17 July 2026. All providers are GPhC-registered pharmacies or CQC-regulated clinics; this is price information, not an offer of supply. Confirm the current price on the provider's own site before ordering.

The cheapest cluster is remarkably tight — everything from Next Script to Fylde Clinic sits inside a £5 band. That's typical for Mounjaro at treatment doses: the keenest pharmacies bunch together, and the real spread comes from the pricier end (Numan, Voy and Envigore all sit near £299). If you want the full grid across every strength, our homepage price table keeps the live figures in one place.

Why 7.5mg costs more than 5mg

The step from 5 mg to 7.5 mg usually adds £40–£60 a month. At The Weight Clinic, for example, 5 mg is £185 and 7.5 mg is £240 — a £55 jump. This is standard: nearly every provider prices each higher strength progressively dearer because the pens contain more tirzepatide.

Dosing is deliberately gradual. You start on 2.5 mg for four weeks, move to 5 mg, and only step up to 7.5 mg after at least another four weeks — and then only if you and your prescriber agree. 7.5 mg is an intermediate maintenance strength; some people stay here, others climb towards 10, 12.5 or the 15 mg maximum. In the SURMOUNT-1 trial, mean weight loss reached around 21% at 10 mg and 22.5% at 15 mg over 72 weeks, so higher doses can deliver more — but the right dose is the one your clinician tailors to you, not the biggest one.

Should you switch pharmacies at 7.5mg?

It's tempting to chase the cheapest £204.99 option once the starter discount runs out. That can absolutely make sense — but weigh a few things first.

The saving over six months

The gap between the cheapest 7.5 mg (£204.99) and a mid-table option like The Weight Clinic (£240) is about £35 a month, or roughly £210 over six months if you stay on 7.5 mg throughout. Real money — but not so large that it should override clinical support, a smooth repeat process or a refund guarantee if things change.

Continuity of care

Switching provider mid-treatment usually means a fresh consultation and sometimes a short gap while your new prescriber reviews you. If your current clinic is reliable and reviews you properly, the admin of moving may not be worth £35. If you're paying a premium price with no added service, switching is a no-brainer.

Check the whole dose ladder

The cheapest provider at 7.5 mg isn't always cheapest at 10 or 15 mg. If you expect to climb, compare the strengths you'll actually use. We do exactly that in our Mounjaro price comparison by dose, and if you're still on the starter pen, our 2.5 mg price comparison and roundup of Mounjaro first-month offers will help you start cheaply before settling on a long-term home.

Safety and eligibility

Mounjaro is a prescription-only medicine, MHRA-licensed for weight management and recommended by NICE (TA1026). Private eligibility is typically a BMI of 30+, or 27+ with a weight-related condition, and a prescriber decides whether it's suitable for you. Common side effects include nausea, diarrhoea, constipation and tiredness; rarer serious risks include pancreatitis and gallstones. If you experience a side effect, report it via the MHRA Yellow Card scheme. This article is price and information only — not medical advice.
