Wegovy Shortages in the UK: Facts, Myths and Your Options

The myth: if your dose is out of stock, you must stop treatment completely

This is the misconception our prescribers hear most often when supply becomes patchy. The reality is more nuanced. Wegovy comes in five dose strengths, and when one is temporarily unavailable, a prescriber can assess whether continuing on a lower strength, pausing briefly, or holding at the most recently available dose is the right course of action for you. Stopping abruptly is rarely the only option, and it is never a decision to make without clinical input.

That matters because the titration schedule for Wegovy is gradual for good reason. Doses run from 0.25 mg up through 0.5 mg, 1.0 mg, 1.7 mg and 2.4 mg, with a newer 7.2 mg option now approved. Each step is managed by a prescriber, and any disruption to that sequence should be managed the same way. If you are mid-titration and your next dose is unavailable, call your prescriber before making any changes. The NHS semaglutide medicines page includes guidance on what to do if a dose is missed or delayed.

The thing patients tell us they wish they had known sooner is that staying in contact with their clinical team during a shortage almost always leads to a better outcome than trying to navigate it alone.

Why Wegovy shortages happen, and how widespread they have been

Demand for semaglutide for weight management surged faster than manufacturing capacity could scale. Novo Nordisk, who makes Wegovy, operates a prioritised allocation system for different markets, which has meant that specific pen sizes or dose cartridges have periodically run short in the UK while others remained available. NHS supply and private supply draw on the same licensed distribution chain, so shortages affect both routes.

Shortage alerts are issued by the MHRA and communicated through the Specialist Pharmacy Service; these are publicly available and worth checking if you are uncertain about the status of your current dose. The NHS England guidance on weight-management injections also provides practical advice for patients and clinicians navigating supply issues.

Shortages have generally been dose-specific and time-limited rather than a blanket absence of the medicine, and if you want to understand whether there is currently a Wegovy shortage affecting your dose, that is an important distinction, because it shapes what options are realistically available to you at any given point. If you want to understand the full range of dose stages within the Wegovy schedule, that context can help you have a more informed conversation with a prescriber about what flexibility exists, and you can find a detailed breakdown of each phase in our guide to the stages of Wegovy, which walks through what to expect at every step of the titration journey.

The safety risk hiding behind shortage anxiety

When legitimate stock is hard to find, some people turn to social-media sellers or unverified websites. This is where the picture becomes genuinely dangerous. The MHRA has issued repeated warnings about counterfeit weight-loss pens sold online, including fake pens found to contain insulin rather than semaglutide, leading to hospitalisations. In 2025 alone, around 20 million doses of illegally traded weight-loss medicines (worth approximately £45 million) were seized, and the first UK site producing counterfeit tirzepatide pens was raided.

The red flags are consistent: sellers offering Wegovy without requiring a prescription from a licensed prescriber, prices significantly below the typical private market range, and discount codes or promotions attached to what are supposed to be prescription medicines. You can verify any online pharmacy before you order by checking the GPhC pharmacy register — a legitimate UK pharmacy will have a premises registration number you can look up in seconds. Suspect sellers can and should be reported via the MHRA Yellow Card scheme.

There is a cost dimension to all of this too. Understanding what a legitimate private prescription actually includes is worth reading if you are comparing options, our weight-loss treatment overview covers what responsible private prescribing looks like, including what to expect from a genuine supply chain.

What to do if you cannot get your Wegovy dose right now

First: contact your prescriber. Do this before your current supply runs out if possible, not after. A prescriber can check real-time stock information, advise on whether staying at your current dose or holding is clinically appropriate, and document any adjustment in your notes so your next review reflects the actual course of treatment rather than an assumed one.

Second: do not order from any source you have not verified. The few pounds saved on a pen from an unknown seller is not a reasonable trade-off against the risks involved, and reading about how the Wegovy shortage has unfolded and what it means for your supply can help you understand why verified pharmacies, which source through the authorised supply chain, give you the clearest picture of availability.

Third: if you are new to Wegovy and wondering whether to start given current supply uncertainties, that is a reasonable question to put to a prescriber at consultation. They can advise on current dose availability, what the titration journey looks like, and whether starting now makes clinical sense. You can read more about Wegovy as a treatment option before you decide, or explore how it compares with other licensed options on the semaglutide overview page. When you are ready, check your eligibility with our prescribers, consultations are free and reviewed the same day by a named GPhC-registered prescriber.
