Wegovy 0.5mg price UK: every provider compared

Looking for the Wegovy 0.5mg price in the UK? This is the second step on the dose ladder — the pen you move to after four weeks on the 0.25mg starter — and prices for it vary far more than most people expect. As of 24 August 2026, a month of Wegovy 0.5mg ranges from about £108.97 to £179 across the regulated pharmacies we track. That's a £70 gap for the identical pen.

Below we set out exactly what each provider charges for the 0.5mg dose, explain why the 0.5mg price matters less than you'd think in the long run, and show you where the genuine savings are.

Wegovy 0.5mg price compared across UK providers

The 0.5mg pen is the first "real" titration step, taken weekly for around four weeks before you move up to 1mg. Here's how the ongoing 0.5mg price compares. All figures were last checked on 24 August 2026 and are per four-week supply.

Why the 0.5mg price shouldn't drive your choice

Here's the thing consumers often miss: 0.5mg is a stepping stone, not a destination. Wegovy is titrated slowly to reduce nausea — 0.25mg for four weeks, then 0.5mg, 1mg and 1.7mg for roughly four weeks each, reaching the usual 2.4mg maintenance dose from around week 17.

So you spend perhaps a month on the 0.5mg pen and then the best part of a year on 2.4mg. A provider that looks cheap at 0.5mg can be expensive where it counts. For example, Numan charges £179 at 0.5mg and £249 at 2.4mg, while Cloud Pharmacy sits at £119.99 for 0.5mg but a much lower £174.99 at 2.4mg.

If you want to see how the whole ladder stacks up, our dose-by-dose price comparison lays all five strengths side by side, and our guide to the real cost at the 2.4mg maintenance dose explains why that number should carry the most weight in your decision.

Watch out for the titration jump

The move from 0.25mg to 0.5mg is where several providers raise their price sharply. Boots, for instance, goes from £89 at 0.25mg to £119 at 0.5mg — a £35 jump. Others, such as Click2Pharmacy, hold a flat £109 across 0.25mg, 0.5mg and 1mg, which can make budgeting simpler in the early months.

This is why a rock-bottom starter month can be a little misleading. If you're weighing up intro offers, our roundup of Wegovy first-month deals ranks them honestly — and reminds you that promo pricing almost always applies only to the 0.25mg starter pen, not the 0.5mg you'll be buying next.

Our recommended provider

For people who value structured support alongside their prescription, The Weight Clinic is our recommended provider. Its 0.5mg price of £125 sits in the middle of the pack, but it bundles monthly video reviews with a prescriber, gives £35 off your first order with code NEWME, and refunds you if the prescriber decides Wegovy isn't suitable for you. That last point matters: a prescriber — not a checkout — decides whether the medicine is right for you.

If you simply want the lowest headline number and are comfortable with a more self-service model, the cheaper GPhC-registered pharmacies above will serve you well. Whatever you choose, only use regulated UK pharmacies. We never list unregulated sellers or "compounded" semaglutide, and we'd urge you to avoid them entirely — you cannot verify what's in them.

How much Wegovy actually helps

Wegovy (semaglutide) is a prescription-only medicine. In the STEP 1 trial, adults on the 2.4mg maintenance dose lost on average about 15% of their body weight over 68 weeks, alongside lifestyle changes, versus roughly 2.4% on placebo. The 0.5mg dose isn't therapeutic on its own — it's part of building tolerance towards that maintenance dose.

Common side effects include nausea (around 40% of people), diarrhoea, vomiting, constipation and headache. Rarer but serious effects include pancreatitis and gallstones. If you experience a side effect, you can report it to the MHRA through the Yellow Card scheme. This article is price and information only and is not medical advice.

NHS or private?

On the NHS in England, Wegovy is available only through specialist weight-management services (NICE TA875), for up to two years, and waiting lists are long. Most people paying for the 0.5mg pen are going private, where access is much wider. If you're torn, our comparison of Wegovy on the NHS versus privately covers both the cost and the wait.
