How many pens of Wegovy do you get per month — and what does that mean for the cost?

Step 1, understanding the one-pen, four-dose monthly rhythm

The Wegovy titration schedule runs through five dose levels: 0.25mg, 0.5mg, 1.0mg, 1.7mg, and the standard maintenance dose of 2.4mg, with dose increases roughly every four weeks as directed by your prescriber. At every single stage, the answer to "how many Wegovy pens per month" is the same: one. Each pen houses four pre-set weekly injections, so if you're curious about how many doses you get per semaglutide pen, the monthly supply unit doesn't change even as the dose climbs.

It's worth knowing that a higher 7.2mg dose has been approved by the MHRA (the dedicated single-dose 7.2mg pen was granted UK marketing authorisation in April 2026) but the starting point and titration path remain the same; your prescriber decides when and whether progression to that level is appropriate for you. You can find out more about the pen format and how the doses work on our Wegovy pen volume and dose guide.

What does shift month to month is the price, because Wegovy pens are priced by strength. A month at 0.25mg costs less than a month at 2.4mg. That graduated pricing is a standard feature of how weight-loss injection treatment works in the UK private market, and it matters when you're working out your total outlay over a full titration course.

Step 2, what private monthly prices actually include (and what they often don't)

Private Wegovy pricing in the UK has moved considerably. Eli Lilly's September 2025 list-price increase for Mounjaro attracted most headlines, but Novo Nordisk's pricing has also shifted, and our guide to what Wegovy costs per month shows how typical private costs now vary meaningfully across providers and dose levels. Our guide to Wegovy's monthly cost in the UK covers the current market context in detail.

The number that matters is not just the pen price. Many providers quote a headline figure that excludes one or more of the following: the clinical consultation, the prescription fee, delivery, and any aftercare or dose-review support. Add those together across several months and the apparent saving over a more inclusive price often disappears, or reverses.

A prescription-only medicine like Wegovy legally requires a clinical assessment before it can be dispensed. That assessment has a real cost. When a price looks unusually low, the first question to ask is which of those components have been quietly removed. Our full monthly cost breakdown walks through exactly what to look for in any quoted price.

Step 3 (how nume prices Wegovy treatment, and why we're not the cheapest

At nume, one price covers the consultation, the prescription, the pen, and free next-working-day delivery) tracked DPD, in a plain box with nothing on the outside to identify the contents. Your aftercare is included for seven days a week. There are no subscription traps and no automatic renewals; each time you need a repeat, a GPhC-registered prescriber reads your notes and re-reviews your case before anything is dispensed. Our clinical team takes that re-review seriously, because your circumstances at month six are not necessarily the same as they were at month one.

We don't position ourselves as the lowest-cost option, and that's a considered choice, not an oversight. A small monthly saving is not a useful measure of value when the medicine in question is a prescription-only treatment with a clinical titration schedule attached. What matters is whether the clinical oversight is real, whether the supply chain is legitimate, and whether someone qualified is actually reading your notes. More about how we work is on our about page.

Current treatment pricing is shown on our treatment page, where you can also begin your free consultation. We don't publish per-pen prices in body copy, but the full price (with nothing excluded) is there. For a broader view of the annual picture, our guide to Wegovy's annual cost is worth reading before you start.

Step 4, why "cheapest per pen" is the wrong question for a prescription medicine

The MHRA has warned publicly and repeatedly about counterfeit weight-loss pens sold through social media and unverified online sellers. Fake pens have been found to contain no active ingredient at all, or in some cases insulin, which at the doses present in a counterfeit semaglutide pen can be acutely dangerous. Large seizures of fake pens have taken place across the UK, and the enforcement picture has escalated significantly since 2023.

The red flags are consistent: sellers offering these medicines without a prescription, prices far below the market range, and the absence of any verifiable GPhC registration. You can check whether any online pharmacy is registered using the GPhC register, it takes thirty seconds and it's the most reliable single check available. Suspect sellers can be reported via the Yellow Card scheme at the link above.

For a prescription medicine at this price point, the right question isn't "who charges the least per pen", it's "is this provider clinically credible, properly registered, and dispensing from the licensed UK supply chain?" Our overview of Wegovy pricing and our general weight-loss treatment guide both cover this in more depth. When you're ready, start your free consultation and a prescriber will review your case the same day.
