Start journey Learn moreWegovy in the UK is supplied as a multi-pack of four pre-filled pens, each containing one weekly dose of semaglutide — so one pack covers a full four-week treatment period. That's the short answer. Each pack is tied to a specific strength, your prescriber determines which strength is right for you, and you move through a stepped titration schedule rather than choosing doses yourself. Because Wegovy is a prescription-only medicine, the whole process begins with a clinical assessment; no two patients start at the same point, and which pack you receive depends on where you are in your treatment journey.

Yes. Each Wegovy multi-pack holds four individual pre-filled injection pens, designed for once-weekly use, so one pack runs for exactly four weeks. The pens come pre-set at a fixed dose (you cannot adjust the amount delivered) and each pen is used once, then safely disposed of. If you have a sharps container at home, that's the right place for used pens.
This four-pen structure applies at every strength in the licensed UK range. Your first pack will almost always be at the lowest starting strength; the prescriber's job is to judge when you're ready to move to the next level. Jumping ahead isn't recommended and, in practice, a reputable pharmacy won't supply a higher-strength pack without seeing evidence of where you are clinically. At nume, that review happens before every repeat order, not just at the start.
One practical point worth knowing: if you'd like to understand exactly what comes in each box before you order, our Wegovy multipack page explains the contents and format in detail. If you tend to order around the same date each month, ordering a few days early (before a bank holiday, say, or a week when you know you'll be away) means you're never caught short. Orders placed by 12pm on a working day are dispatched the same day once clinically approved, arriving via tracked DPD the following working day.
The titration pathway for Wegovy runs in steps: 0.25 mg to start, then 0.5 mg, 1.0 mg, 1.7 mg, and 2.4 mg as the standard maintenance dose. Since January 2026 there has also been a 7.2 mg option, initially supplied as three 2.4 mg pens per week, and from April 2026 available as a dedicated single-dose 7.2 mg pen following MHRA approval of the new pen format. The 7.2 mg pen is licensed specifically for adults with a BMI of 30 or above; your prescriber will assess whether it's appropriate for you.
Most people spend roughly four weeks at each step before moving up, though that timeline is guided by how well the current dose is tolerated. If nausea or other gastrointestinal symptoms are significant, staying at a lower strength a little longer is a reasonable clinical decision. The NHS semaglutide medicines page gives a clear overview of what to expect at each stage, and it's worth reading before your first injection.
For patients transferring from another provider, the pack strength dispensed needs to match where you currently are, which is why transfer patients are asked to provide evidence of their existing dose before a new prescription is issued. It's a safety step, not a bureaucratic one. You can read more about how semaglutide works as a treatment on our semaglutide overview page.
Wegovy is not available on the NHS for most people at present; the NICE recommendation (TA875) restricts NHS supply to specialist weight-management services with multidisciplinary support, so the majority of people access it privately. Private pricing varies between providers and by dose strength. When comparing costs, it's worth checking what the headline figure actually covers, some clinics charge separately for the consultation, the prescription, and delivery on top of the medicine price.
A single transparent price that bundles clinical review, prescription, the treatment itself, and free next-working-day delivery is worth more than a lower headline that adds fees at checkout. For a fuller picture of what Wegovy typically costs in the UK and what to look for, our Wegovy cost page breaks it down clearly.
Wegovy is a prescription-only medicine, which means the price you pay should always reflect a genuine clinical assessment, not just a transaction. If a price looks unusually low, or if a seller is offering semaglutide pens without a consultation, that's a reason to stop and check. The MHRA has warned publicly about counterfeit weight-loss pens circulating online; verifying any pharmacy on the GPhC register takes about thirty seconds and is the simplest check you can do.
The 0.25 mg introductory pack is sometimes described separately as a starter pack, because it's the entry point for anyone beginning Wegovy for the first time. Functionally it's the same format (four pens at the 0.25 mg strength) and it leads directly into the titration sequence. Some people find it useful to understand this distinction before their first consultation, particularly if they're comparing options or have previously used a different treatment. Our Wegovy starter pack page covers what that first pack contains and what the initial weeks typically look like.
For patients who've already completed the titration and are maintaining at 2.4 mg or higher, the ongoing supply is simply the next pack in sequence. There's no separate product category for maintenance packs; the multi-pack format is consistent throughout treatment. If you're thinking about whether Wegovy is the right fit for your situation, the Wegovy treatment overview is a good place to start, and our clinical team is available through the consultation page if you want a prescriber's view on your specific circumstances.
One final note on vitamins: some patients ask whether they need to take supplements alongside Wegovy. Appetite suppression can reduce overall food intake, and getting enough micronutrients matters. Our page on Wegovy and multivitamins looks at what the evidence says and what our prescribers typically discuss at review.
