How much does 7.5 mg Mounjaro cost in the UK?

Step 1: understand what you're actually comparing when you see a price

When someone searches for the cost of 7.5 mg Mounjaro, they usually find a range of figures scattered across pharmacy and clinic websites. Those numbers are rarely comparing like for like. Some quoted prices cover the pen only; others fold in a prescription fee that's listed separately at checkout; others charge a monthly membership on top of the medicine price. The result is that a headline figure £30 lower than a competitor's can end up costing more once you've added the consultation, the prescription charge, and the delivery fee.

The honest picture: UK private pricing for 7.5 mg Mounjaro sits roughly in the £149–£375 per four-week pen bracket across providers, hedged because individual pharmacy pricing shifts and the September 2025 Lilly price increase moved the floor on several doses. For broader context on how Mounjaro pricing works across the full dosing range, our Mounjaro pricing overview lays this out in detail.

Because this is a prescription-only medicine, any legitimate supply must involve a prescriber's clinical sign-off. The prescription itself has a cost to produce, either charged explicitly or built into what you pay. If you're wondering how much the 2.5 mg starting dose costs, that page is a useful reference point for understanding how the pricing structure begins before you step up through the range. If a price seems to exclude it entirely, that's a signal worth investigating before you hand over card details.

Step 2: know what a legitimate all-inclusive price should cover

A question our prescribers hear most weeks is whether it's worth paying more for a service that includes aftercare. The answer, practically speaking, is that dose changes (moving from 5 mg to 7.5 mg, or from 7.5 mg toward 10 mg) require a clinical reassessment each time. If your provider charges separately for that review, the cost of treatment compounds quickly. Our dedicated 7.5 mg price page covers what's included at this specific dose at nume.

A genuinely all-inclusive price for a prescription weight-loss medicine should cover: the initial clinical consultation, the prescription itself, the medicine, delivery, and access to clinical support between doses. If any of those five elements appears as a line item at checkout, you're not looking at a transparent price. Our guide to Mounjaro costs across all doses breaks this down further for anyone comparing multiple providers at once.

For reference, the 5 mg dose is typically the previous step before 7.5 mg, and some patients stay at 5 mg long-term if it suits them clinically. The 10 mg pen is usually the next step up. Pricing across this range follows the same principle: what matters is what comes with it, not just the pen price in isolation.

Step 3: why 'cheapest' is the wrong test for a prescription medicine

nume is not the cheapest option in the UK private market. That's deliberate. One transparent price covers the consultation, the prescription, the medicine, free tracked next-day delivery, and 7-day aftercare, nothing billed separately, no subscription pulling a repeat payment without fresh clinical review. You can read more about the service and the team behind it on our about us page.

Price is a reasonable thing to care about. But for a Prescription-Only Medicine like Mounjaro, the cheaper listing often answers the wrong question. The MHRA has issued public warnings about counterfeit weight-loss pens sold through unverified online sellers, including fake tirzepatide pens seized in the UK in 2025. Genuine supply comes through the licensed UK supply chain; any seller offering these medicines without requiring a clinical assessment first is a red flag, not a bargain. You can verify any online pharmacy's registration on the GPhC pharmacy register.

NICE's appraisal of tirzepatide, TA1026, sets out the clinical criteria under which this medicine is recommended, which underlines that it is a serious medical intervention, not a consumer product where the lowest price wins. The right question isn't which provider is cheapest; it's which provider can demonstrate safe, clinically supervised, genuine supply. That's the standard worth holding any pharmacy to, including ours. Current treatment pricing at nume is shown on the consultation and treatment page, and a free clinical review is where to start if you want to find out whether 7.5 mg is right for you.
