Can I Use Klarna for Mounjaro? (October 2026)

01 · Payment

How Klarna works for a Mounjaro order

Klarna is a payment option at checkout, not a way around the prescription. You complete a free online consultation and a GPhC-registered prescriber reviews it; payment is taken when you place the order. If the prescriber decides Mounjaro is unsuitable, the order is refunded automatically in full.

Klarna runs its own eligibility and soft credit checks, so being approved for Mounjaro does not mean Klarna will accept you. If Klarna declines, you can pay by Visa or Mastercard instead, or use our pay-monthly options.

02 · Cost

What you are paying for

The Mounjaro pen is priced per four-week pen. Your first 2.5mg pen costs £129.99 with code FIRST40 (standard price £169.99). Every later order is £25 off the standard price, with code DOSE25. The consultation is free and the price shown is the price paid, with no hidden fees.

If you step up after 4 weeks on each dose, your first four pens (2.5mg to 10mg) cost £959.96 at standard prices; a new customer's first order is £40 less and every later order £25 less. Instalments spread the cost but do not reduce it, so check Klarna's terms on any interest or late fees before you commit.

03 · Who can get Mounjaro

Who can get Mounjaro, however you pay

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 assesses your BMI, medical history and current medicines before deciding if it is suitable.

Mounjaro is also available on the NHS, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus a weight-related condition, and the primary-care rollout began in June 2025 with the highest-need groups first.⁴ Many people who meet the licensed criteria choose regulated private treatment instead of waiting. See our weight loss clinic for more.

04 · What to expect

What to expect from treatment

In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of their 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 Treatment is a longer commitment than one pen, so consider whether instalments suit your budget over several months.

05 · Ordering steps

How ordering works
