If you're about to start Wegovy, the first pen you'll ever pay for is the 0.25mg starter dose — and the Wegovy 0.25mg price in the UK ranges from around £79.99 to £164 for four weeks. That's an £84 gap for the identical medicine, so it pays to know what a fair price looks like before you hand over any card details.
This guide walks you through what the starter dose actually is, what UK pharmacies charge for it, why the price jumps as you move up doses, and how to avoid overpaying on your very first order. Prices below were last checked on 24 August 2026.
Key takeaway: The 0.25mg dose is a low-strength introduction, not a working weight-loss dose — so it's usually the cheapest pen you'll buy. The lowest standard price we track is £79.99/4 weeks (Next Script), but discounted first-month deals can drop your opening spend to around £59.99. Always check the ongoing price too, because that's what you'll pay month after month.
What is the Wegovy 0.25mg starter dose?
Wegovy (semaglutide) isn't started at full strength. To reduce nausea and let your body adjust, the dose is increased gradually over roughly 16 weeks:
- 0.25mg weekly for the first 4 weeks
- then 0.5mg, 1mg and 1.7mg (about 4 weeks each)
- reaching the usual maintenance dose of 2.4mg from around week 17
So 0.25mg is a settling-in dose. You shouldn't expect much weight change in month one — the appetite-lowering benefit builds as you titrate upwards. In the STEP 1 trial, the average weight loss of about 15% was achieved at the 2.4mg dose over 68 weeks, not at the starter strength.
Because it's the entry point, most pharmacies price the 0.25mg pen at or near the bottom of their range — and many run a first-month discount to win your business.
Wegovy 0.25mg price UK: how pharmacies compare

You can see the full ongoing price list across every dose on our homepage price table. A couple of things stand out:
- The cheapest ongoing 0.25mg price is £79.99 (Next Script), with several pharmacies clustered around £88–£89.
- The lowest first-month price is £59.99 at MedExpress and ZAVA — genuinely useful if you want the smallest possible opening cost.
- A low first month doesn't always mean a low ongoing price. Some providers offer a big opening discount, then settle at a higher monthly rate.
Why the first-month price can be misleading
A £59.99 opening offer looks brilliant next to £89 — but you'll only pay the starter price for four weeks. From week five you move to 0.5mg, then higher, and the cost climbs. What matters over a full course is the price of the doses you'll spend most of your time on, especially the 2.4mg maintenance dose.
For example, the 2.4mg dose ranges from about £135 (Medicine Marketplace) to £266 (Envigore) per four weeks. So a cheap starter month is nice, but it's the maintenance price that decides your real long-term spend. We break the whole journey down in how much does Wegovy cost in the UK.
If you'd rather not chase the absolute lowest headline number, our recommended provider is The Weight Clinic. Their 0.25mg starter month is £80 with the code NEWME (£35 off your first order), they include monthly video reviews as you titrate, and they refund you in full if the prescriber decides Wegovy isn't right for you.
What you actually get for your money at 0.25mg
Whatever you pay, a legitimate 0.25mg order should include:
- A genuine, branded Wegovy pen (four weekly 0.25mg doses)
- An online consultation reviewed by a prescriber — not automatic approval
- Tracked, discreet delivery, usually within a few days
- Clear aftercare and a way to report side effects
Eligibility is typically a BMI of 30 or more, or 27+ with a weight-related condition such as high blood pressure. A prescriber decides whether Wegovy is suitable for you — no reputable UK provider guarantees approval. For a walk-through of the questions you'll be asked, see what providers ask in a Wegovy online consultation.
Side effects to expect on the starter dose
The 0.25mg dose exists precisely to ease you in gently, but side effects can still happen. The most common are nausea (affecting around 40% of people), diarrhoea, vomiting, constipation and headache. These often settle as your body adjusts.
Rarer but serious risks include pancreatitis, gallstones and a rare eye condition (NAION). If you experience anything worrying, contact your prescriber and report it via the MHRA Yellow Card scheme. This article is price and information only — it isn't medical advice.
How to buy your first pen without overpaying
A few simple checks keep you safe and save money:
- Confirm the provider is regulated — a GPhC-registered pharmacy or CQC-regulated clinic. See our 7 checks before you pay.
- Compare the ongoing price, not just the opening deal.
- Use a legitimate discount code where available — the codes in the table above are genuine.
- Never buy from unregulated sellers or anyone offering "compounded" semaglutide — these are not the licensed medicine and carry real risks.
You don't need a GP referral to order privately, though NHS access exists in limited cases through specialist services. More on that in can you get Wegovy without your GP.

Frequently asked questions
What is the cheapest Wegovy 0.25mg price in the UK?
The lowest ongoing 0.25mg price we track is £79.99 for four weeks at Next Script, with several pharmacies at around £88–£89. For first-month deals, MedExpress and ZAVA drop the opening cost to £59.99. Always check the ongoing price too, as that's what you'll pay after the introductory offer ends.
Why is the 0.25mg dose cheaper than higher doses?
0.25mg is a low-strength starter dose used only for the first four weeks to reduce nausea. Prices rise as you titrate up towards the 2.4mg maintenance dose, which is usually the most expensive pen you'll buy from around week 17 onwards.
Will I lose weight on the 0.25mg starter dose?
Probably not much. The 0.25mg dose is designed to let your body adjust, not to deliver the full benefit. Meaningful appetite reduction and weight loss build as you increase to higher doses — the ~15% average loss in the STEP 1 trial was seen at the 2.4mg dose over 68 weeks.
Is a first-month discount worth it?
It can lower your opening cost, but it only applies to the starter dose. Because prices climb as your dose increases, the maintenance price matters far more over a full course. Compare the ongoing figures before choosing on the first-month deal alone.
Can I get a refund if I'm not approved for the starter dose?
With reputable providers, yes. The Weight Clinic, for example, refunds you in full if the prescriber declines your request. Check any provider's refund policy before paying, and avoid sites that take payment with no mention of what happens if you're turned down.
Do I need a prescription for Wegovy 0.25mg?
Yes. Wegovy is a prescription-only medicine at every dose. A prescriber reviews your online consultation and decides whether it's suitable — no legitimate UK provider offers guaranteed approval. See our guide on getting a Wegovy prescription online.
