Asda Mounjaro Prices (2026): Complete UK NHS vs Private Guide

Mounjaro (tirzepatide) has become one of the most talked-about injectable medicines in the UK—used for type 2 diabetes and (now) weight management in eligible adults. But when people search “Asda cost of Mounjaro,” they’re often trying to answer a bigger question:

“What will I actually pay—on the NHS versus going private?”

This guide breaks down the real-world costs and the decision points that matter (eligibility, dose changes, safety, and how to avoid being overcharged or misled), using the most recent UK guidance available as of 4 February 2026.

The quick answer: what does Mounjaro cost at Asda?

There are two main ways people access Mounjaro “through Asda”:

1. Asda Pharmacy (dispensing a prescription you already have—NHS or private)
2. Asda Online Doctor (a private online prescribing service that supplies Mounjaro if you’re suitable)

Here’s the cost picture at a glance.

Typical costs you might see (UK)

Note: Asda Pharmacy’s online medicines catalogue lists Mounjaro at £159.00 and also notes a minimum prescription dispensing charge of £9.15 per item—but you should confirm exactly what that means for your prescription (strength/quantity, private vs NHS, delivery) before ordering.

What is Mounjaro—and what is it licensed for in the UK?

Mounjaro is the brand name for tirzepatide, a once-weekly injection.

In the UK it is authorised for:

• Type 2 diabetes (blood sugar management)
• Weight management in adults with BMI ≥30, or BMI 27–29.9 with at least one weight-related health problem (alongside diet and physical activity) (gov.uk)

That second point is important because some older articles still describe Mounjaro as diabetes-only—but the MHRA authorised a weight-management indication in November 2023. (gov.uk)

Option 1: Getting Mounjaro on the NHS and using Asda Pharmacy

NHS price at Asda: what you pay at the counter

If you’re in England and you’re not exempt, you pay the standard NHS prescription charge of £9.90 per item. Charges have been frozen at £9.90 (including plans for 2026/27). (nhsbsa.nhs.uk)

Many people pay £0 because they qualify for exemptions (for example, some people with diabetes qualify for a medical exemption certificate). (gov.uk)

Who can get Mounjaro on the NHS?

NHS access depends on why it’s being prescribed.

For type 2 diabetes

NICE recommends tirzepatide for some adults with type 2 diabetes when previous treatments haven’t controlled blood sugar adequately and certain criteria are met (including BMI-related considerations and clinical factors). (nice.org.uk)

For weight management (overweight/obesity)

NICE guidance (TA1026) recommends tirzepatide only for adults with:

• BMI ≥35, and
• at least one weight-related comorbidity

…and it includes a rule to reassess continuation if <5% weight loss after 6 months on the highest tolerated dose. (nice.org.uk)

Access is also phased (not everyone will be eligible immediately). NICE notes staged eligibility, with broader access expected around June 2026 and around March 2027 for certain groups. (nice.org.uk)

NHS England has also issued interim commissioning guidance for implementing tirzepatide within weight management services and primary care pathways during rollout. (england.nhs.uk)

Practical NHS tips

• Ask your GP/clinic which pathway applies (diabetes vs weight management) and whether your area is prescribing under the current rollout.
• Call your local Asda Pharmacy before you go to confirm stock (Mounjaro requires cold-chain handling).
• If you pay NHS charges regularly, check if a Prescription Prepayment Certificate (PPC) saves money. The PPC prices have been frozen (3-month and 12-month options). (gov.uk)

Option 2: Going private via Asda (and what it really costs)

Private costs are where most confusion happens—because the total isn’t just “the pen price.”

Private price benchmarks: what the medicine itself costs

NICE lists UK list prices (excluding VAT) for a 4-week supply of tirzepatide pens as: (nice.org.uk)

• £133 (2.5 mg)
• £180 (5 mg)
• £255 (7.5 mg and 10 mg)
• £330 (12.5 mg and 15 mg)

NHS pricing can differ due to confidential commercial arrangements—so these list prices are most useful as a reference point when comparing private providers. (nice.org.uk)

Asda Online Doctor: published Mounjaro prices by dose

Asda Online Doctor states that each Mounjaro pen lasts 4 weeks and lists these prices (page last reviewed 27 January 2026): (onlinedoctor.asda.com)

• 2.5 mg: £168.97
• 5 mg: £188.97
• 7.5 mg: £248.97
• 10 mg: £278.97
• 12.5 mg: £288.97

(If you’re comparing across providers, always check whether follow-up support, delivery, needles, and check-ins are included.) (onlinedoctor.asda.com)

If you bring a private prescription to Asda Pharmacy

If you already have a private prescription (for example, from a private GP or another clinic), Asda Pharmacy may be able to dispense it—but private dispensing prices vary and can include dispensing fees.

Asda’s online medicines listing shows:

• £159.00 displayed for Mounjaro
• A note stating “minimum prescription dispensing charge of £9.15 per item” (pharmacy.asda.com)

Because private pricing can depend on the exact strength/pack and supply route, the best move is to ask for a full price breakdown before you commit.

Budget for the “hidden” private costs

When people get surprised by the total, it’s usually because of one or more of these:

• Initial assessment / consultation fees (some services bundle this into the medication price)
• Follow-up check-ins (especially during dose escalation)
• Delivery fees / cold packaging
• Pen needles (needles are not included with Mounjaro KwikPen packs) (medicines.org.uk)
• Sharps bin for safe disposal
• Extra support programmes (helpful for some people, unnecessary for others)

How to save money

1) If you pay NHS charges, check whether a PPC makes sense

With the NHS charge at £9.90 per item, a PPC can be good value if you need multiple prescription items.

• 12-month PPC (£114.50) breaks even at about 12 items/year
• 3-month PPC (£32.05) breaks even at about 4 items/3 months (gov.uk)

2) Don’t let “dose escalation” blindside your budget

Many people start on a lower dose and increase over time. When comparing private prices, look at the highest dose you might reach, not just the month-one offer.

3) Compare like-for-like support

Cheaper isn’t always better if it comes with:

• minimal clinical monitoring
• poor side-effect support
• unclear prescribing criteria

But expensive isn’t automatically better either. Ask what’s actually included.

Storage, travel, and injection supplies

Mounjaro KwikPen storage guidance in the UK SmPC includes: (medicines.org.uk)

• Store unused pens in a refrigerator (2°C–8°C)
• Do not freeze
• After first use, it can be stored up to 30 days at temperatures not above 30°C (then discard)

Side effects: what’s common, what’s urgent

Most side effects are gastrointestinal (nausea, vomiting, diarrhoea, constipation) and often occur when starting or increasing the dose.

When to seek urgent medical help

In January 2026, the MHRA updated guidance and product information highlighting a small risk of severe acute pancreatitis with GLP‑1 medicines (including dual GLP‑1/GIP agonists). Seek urgent care for severe, persistent stomach pain (possibly radiating to the back), especially with nausea/vomiting. (gov.uk)

If you experience suspected side effects, report them via the Yellow Card scheme. (gov.uk)

Frequently asked questions

Can I get Mounjaro on the NHS from my GP and pick it up at Asda?

If you’re prescribed Mounjaro on the NHS (for type 2 diabetes or via the weight management pathway during rollout), you can typically have it dispensed at a community pharmacy such as Asda—subject to local availability and policies. (nice.org.uk)

Is Mounjaro licensed for weight loss in the UK?

Yes. The MHRA authorised Mounjaro (tirzepatide) for weight management and weight loss in adults meeting BMI criteria in November 2023. (gov.uk)

Why do private prices vary so much?

Because private providers set their own pricing and may bundle (or not bundle) clinical reviews, delivery, needles, and support—while the underlying medicine has dose-dependent list prices. (nice.org.uk)
