Ask "Mounjaro vs Wegovy price" and you want one number, not a lecture. Here it is: across the 24 UK pharmacies we track, Wegovy is the cheaper jab at almost every matched point on the dose ladder. But the gap is smaller than the headlines suggest, it narrows as your dose climbs, and the pharmacy you pick moves the price more than the medicine does. This page settles the money question and shows you exactly where the two drugs sit.
On like-for-like doses Wegovy usually wins on price — a typical early-maintenance month runs around £148 for Wegovy against roughly £190 for Mounjaro. But the cheapest Mounjaro can undercut the dearest Wegovy, so the provider you choose matters as much as the molecule.
Why comparing the two on price is tricky
Mounjaro (tirzepatide) and Wegovy (semaglutide) are priced per pen, and each pen covers roughly four weeks. The catch is that the two drugs climb entirely different dose ladders, so there is no single "Mounjaro price" or "Wegovy price" — there's a price at every rung.
Mounjaro steps up 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg. Wegovy steps up 0.25 → 0.5 → 1 → 1.7 → 2.4 mg. As the milligrams rise, so does the pen price — for both drugs. That means a fair "which is cheaper" answer has to compare the stage of treatment you're at, not just two numbers pulled off a shelf.
To keep it honest, we line the drugs up at the points most people actually pay for: the low starter month, an early maintenance dose, and the full top dose.
Mounjaro vs Wegovy price, dose by dose
The table below shows the cheapest and typical (median) ongoing prices across all 24 tracked pharmacies, per four-week pen, at matched stages of each ladder. Prices last checked 4 July 2026.
| Stage of treatment | Mounjaro dose | Wegovy dose | Cheapest Mounjaro | Cheapest Wegovy | Typical gap |
|---|---|---|---|---|---|
| Starter month | 2.5 mg | 0.25 mg | £145.99 | £79.97 | Wegovy ~£66 cheaper |
| Early maintenance | 5 mg | 1 mg | £173.99 | £109 | Wegovy ~£42 cheaper (median) |
| Full / top dose | 15 mg | 2.4 mg | £288.99 | £174.99 | Wegovy ~£118 cheaper (median) |
Typical gap uses the median ongoing price across all tracked pharmacies at each dose: Mounjaro 5 mg ≈ £190 vs Wegovy 1 mg ≈ £148; Mounjaro 15 mg ≈ £318 vs Wegovy 2.4 mg ≈ £200. Confirm every figure on the provider's own site before ordering.
Read the table and the pattern is clear: at every rung, the cheapest Wegovy beats the cheapest Mounjaro. The absolute gap actually widens at the top of the ladder, because Mounjaro's higher doses carry the biggest pen prices in the market.
So is Wegovy always the cheaper choice?
Not automatically. Two things blunt the "Wegovy is cheaper" rule.
First, the pharmacy spread is huge. The same Mounjaro 2.5 mg starter pen ranges from about £145.99 to £229 depending on where you buy — a swing of over £80 for an identical medicine. Wegovy's starter month ranges from roughly £79.97 to £164. In other words, a well-chosen Mounjaro can cost less than a badly-chosen Wegovy. The provider decision is doing a lot of the work.
Second, price isn't the only currency. Mounjaro tends to produce more average weight loss than Wegovy in trials, so a higher monthly cost can buy more result per pound. If your goal is measured in kilograms rather than only in pounds sterling, "cheaper" and "better value" aren't the same thing. We weigh that trade-off in our Mounjaro vs Wegovy results comparison.
Almost every pharmacy discounts the starter pen, then charges full price from month two. A tempting £59–£79 first month can sit above a rival's ongoing price by dose 3. Always compare the ongoing price at the dose you'll actually settle on, not the loss-leader.

Consultations are free, needles are included, there are monthly video reviews with a clinician, and — the part that matters most for the money question — you're refunded if you're declined, so a consultation that ends in "not suitable" doesn't cost you.

How to actually pay less — for either drug
- Compare at your settling dose. If you expect to stabilise on Mounjaro 10 mg or Wegovy 1.7 mg, price that rung across pharmacies, not the starter.
- Separate promo from ongoing. A big first-month discount is worth having, but the price from month two is what you'll pay for most of the year.
- Check what's bundled. Free delivery, needles, sharps bins and clinician check-ins have real value; a headline price without them can be the false economy.
- Use a valid first-order code. Many pharmacies run £10–£50 off new-customer offers — but a code you don't qualify for is worth nothing, so read the small print.
- Don't chase the impossible. If a price looks far below the £80–£150 band starter pens sit in, treat it as a red flag, not a bargain. Only ever buy from a GPhC/CQC-regulated UK pharmacy.

Frequently asked questions
Which is cheaper, Mounjaro or Wegovy?
At matched stages of the dose ladder, Wegovy is usually cheaper. A typical early-maintenance month is around £148 for Wegovy versus roughly £190 for Mounjaro, and the gap widens at top doses (Wegovy 2.4 mg ≈ £200 vs Mounjaro 15 mg ≈ £318 as a median). But the cheapest Mounjaro can undercut the dearest Wegovy, so the pharmacy you choose matters too.
Why does Mounjaro cost more than Wegovy?
Mounjaro is a dual-hormone medicine (it acts on both GIP and GLP-1 receptors) and tends to produce more average weight loss in trials. Its pens — especially at higher doses — carry the market's top prices. You're generally paying more per month, but potentially getting more result per pound.
How much does a month of Mounjaro or Wegovy cost in the UK?
Across the 24 pharmacies we track, Mounjaro starter pens run from about £145.99 and rise to roughly £288.99–£359 at the top dose. Wegovy starts from about £79.97 and reaches around £174.99–£249 at 2.4 mg. Each pen covers about four weeks. Confirm the current figure on the provider's site.
Do the two drugs cost the same at every dose?
No. Both drugs get more expensive as the dose climbs, but on different ladders. That's why a fair comparison lines them up by stage of treatment — starter, early maintenance, full dose — rather than picking two random pen prices.
Are the cheapest prices safe to use?
Yes, provided the pharmacy is UK-registered with the GPhC and/or CQC — every provider in our table is. A price far below the normal £80–£150 starter band, or any seller offering these medicines without a prescription, is a warning sign. Never buy from unregulated sellers or "compounded" versions. Report suspected side effects via the MHRA Yellow Card scheme.
If you've decided on Mounjaro or Wegovy, The Weight Clinic is our recommended provider: competitive everyday pricing, free consultation, monthly clinician video reviews, needles included, and a full refund if you're declined — so the assessment never costs you. New patients get £35 off with code NEWME.
