Reaching the Maximum Wegovy Dose: What That Decision Actually Involves

Which dose is actually the maximum, and why there are now two answers

For most of Wegovy's licensed history in the UK, the maximum weekly dose of semaglutide for weight management was 2.4mg. That figure remains the standard maintenance target for most patients today. But in January 2026 the MHRA approved a higher regimen (7.2mg per week) initially delivered as three simultaneous 2.4mg injections. A dedicated single-dose 7.2mg pen followed on 14 April 2026, making it far simpler to administer.

The 7.2mg approval matters for one practical reason: trials reported around 20.7% average weight loss over 72 weeks at this dose, bringing results closer to what the highest doses of tirzepatide produce. That narrowing of the gap is clinically significant for patients who haven't reached their target at 2.4mg. You can read more about how these doses compare and what the evidence says on the Wegovy doses overview.

It is worth being clear, though: the 7.2mg dose is licensed specifically for adults with a BMI of 30 or above and is not approved for the cardiovascular indication. Starting dose remains 0.25mg regardless of target, and the full titration schedule still applies. No shortcuts. A prescriber decides whether the higher ceiling is appropriate for a given patient, it isn't simply available on request.

The titration ladder: why you can't start at the top

Semaglutide's most common side effects are gastrointestinal: nausea, loose stools, indigestion, and sometimes vomiting. These effects are dose-dependent and most pronounced when the dose changes. The titration schedule (0.25mg, then 0.5mg, 1.0mg, 1.7mg, and 2.4mg, each held for roughly four weeks before the next step) exists to give the gut time to adapt at each level.

Jumping to 2.4mg from the outset would, for most people, mean a significantly harder experience. The schedule is protective, not bureaucratic. If you want to understand what the maximum dose of semaglutide involves and why reaching it takes time, the titration pathway is central to that answer. The 7.2mg route adds further time on top of that, since 2.4mg must be well-established before any escalation.

The NHS guidance on weight-management injections covers this titration principle clearly, and the NHS semaglutide page sets out the dose pathway in plain terms. What that page cannot do is tell you where your own titration should land, that is the prescriber's call, made in light of your response, your tolerance, and whether the results at each level are meeting the clinical threshold.

The dose that produces the most weight loss

The short answer: generally, the highest tolerated dose. Trial data consistently show a dose-response relationship with semaglutide, patients at 2.4mg lost more weight on average than those who stopped at lower maintenance doses, and data at 7.2mg extend that pattern further. The STEP 1 trial, published in the New England Journal of Medicine, found roughly 15% average body-weight reduction at 2.4mg over 68 weeks, with significant individual variation around that mean.

Individual variation is the operative phrase. Some patients achieve their clinical target at 1.0mg or 1.7mg and there is no clinical reason to push higher. Others plateau at 2.4mg and may, with prescriber agreement, be candidates for the 7.2mg regimen. Our page on the maximum dose of semaglutide for weight loss explores that clinical picture in more depth, because the right ceiling is genuinely person-specific, and the question of which Wegovy dose produces the most weight loss deserves a longer answer than any single page can give, because it is genuinely person-specific.

If you are considering where your own treatment should head, our clinical team reviews every patient's progress before any repeat or dose change. That review is done by a GPhC-registered prescriber, personally, before anything is dispensed.

Practical matters: what the highest-dose pen looks like and what to do next

The dedicated 7.2mg single-dose pen carries a pre-set dose, there is no dial, no user adjustment. It locks after use. For patients used to the standard Wegovy pen this feels straightforward; the main practical difference is the auto-dosing mechanism and the built-in covered needle. If you are still working out what the maximum dose of semaglutide actually is for your circumstances, the pen you are dispensed will reflect the prescriber's decision at that stage of your treatment. Like all Wegovy pens it requires refrigerated storage between 2°C and 8°C, and the Patient Information Leaflet specifies the exact room-temperature window if you need to travel, refer to that, not to memory.

When a pen is dispensed through nume it arrives with DPD the next working day, tracked to your phone, in plain unbranded packaging. The pen itself is exactly what the licensed UK supply chain delivers, not a parallel import or a compounded version.

For anyone weighing up the cost of private treatment at higher doses, the treatment page sets out what is included in one transparent price, consultation, prescription, delivery, and aftercare, with no subscription attached. Understanding the full picture before starting is worth the few minutes it takes.

If you'd like to discuss where the maximum dose fits your situation, our prescribers are available seven days a week. Speak to our prescribers through a free consultation, reviewed the same day, with no obligation to proceed.
