Mounjaro is one of the most effective weight loss treatments available in the UK, but the monthly cost can add up quickly. Fortunately, many GPhC-registered pharmacies offer discount codes — particularly for first-time patients — that can significantly reduce the cost of your first order.
A Mounjaro discount code is a promotional code that you enter at checkout on a pharmacy's website to receive a reduction in price. Most codes are offered to new patients only, though some pharmacies offer loyalty codes for returning customers. Discounts typically range from 10% to 50% off the first month's supply.
Over 40 of the 63 pharmacies we track currently offer some form of discount code or introductory offer. The most generous codes tend to come from newer market entrants trying to build their patient base. Here are some of the most consistently available codes:
| Pharmacy | Code | Discount | Valid For |
|---|---|---|---|
| MedExpress | MEDEX50 | £50 off first order | New patients |
| Zava | ZAVA40 | £40 off first order | New patients |
| Numan | NUMAN30 | £30 off first order | New patients |
| Second Nature | NATURE50 | £50 off first order | New patients |
| Juniper | JUNIPER25 | 25% off first month | New patients |
| Voy | VOY20 | £20 off first order | New patients |
Always check the full price after applying the code — sometimes a pharmacy with a large discount code is still more expensive than a competitor without one.
- Compare the post-discount price across multiple pharmacies — the best code isn't always the biggest saving
- Check for free consultation offers — some pharmacies charge £20–£50 for the initial consultation
- Look for bundle deals — some pharmacies offer discounts for paying 3 months upfront
- Sign up for price alerts — we notify you when prices drop below your target
- Check the maintenance pharmacy list — if you've reached your target weight, you may qualify for cheaper maintenance pricing
