What's the highest dose of semaglutide you can take?

What is the highest approved dose of semaglutide injection for weight loss?

Until January 2026, 2.4mg weekly was the answer to this question. That changed when the MHRA approved a higher 7.2mg weekly maintenance dose for Wegovy, initially supplied as three 2.4mg pens used in the same week. Then, on 14 April 2026, regulators approved a dedicated single-dose 7.2mg pen: one injection per week, pre-set, with a covered needle that locks after use. You can read the official announcement on GOV.UK.

The 7.2mg pen is licensed for adults with a BMI of 30 or above; it is not authorised for the cardiovascular indication or for BMI below 30. The starting dose remains 0.25mg, titrated roughly every four weeks by your prescriber through 0.5mg, 1.0mg, 1.7mg, 2.4mg, and upward to 7.2mg at the maximum. That titration ladder exists for a reason, pushing up too quickly significantly increases GI side effects. Your prescriber sets the pace.

It is worth being clear about what 7.2mg means in practice. Trials at this dose reported average weight loss of around 20.7% over 72 weeks, which narrows the gap considerably with tirzepatide at its highest dose. But averages mask a wide range of individual responses, and the trial population matters. If you are weighing up options, our page on Wegovy doses covers each step in the titration schedule in more detail.

Does the oral Wegovy tablet reach a higher dose than the injection?

Numerically, yes, but the comparison is misleading without context. The Wegovy tablet (approved by the MHRA on 11 June 2026, the first oral GLP-1 licensed for weight management in the UK) reaches a maintenance dose of 25mg daily. The schedule runs 1.5mg, then 4mg, then 9mg, then 25mg, spending at least a month at each level.

That number sounds far larger than 7.2mg, but it is not a stronger medicine. Oral semaglutide is absorbed very inefficiently through the gut, that is why the tablet dose needs to be much higher to deliver a comparable effect in the bloodstream. The two forms are not directly comparable by their number on the box. The OASIS 4 trial reported around 13.6% average weight loss over 64 weeks among people taking the tablet; among those who adhered fully to treatment, that figure was closer to 17%.

One practical distinction: the tablet requires no refrigeration and no injection, which suits some people well. It does demand a strict morning routine, taken on an empty stomach, with a small amount of plain water, at least 30 minutes before food or any other oral medicine. Our prescribers can help you work out which form fits your circumstances better. You can also explore more about the highest dose of Wegovy across both injection and tablet formulations.

What stops you from simply taking a higher dose yourself?

If you have ever felt frustrated by slow titration (especially when weight loss seems to plateau early) you are not alone. Lots of people ask whether they can speed things up. The honest answer is that the titration schedule is not bureaucratic caution; it reflects how GI side effects scale with dose. Nausea, vomiting and diarrhoea are the most common reasons people stop treatment, and most of those cases involve doses that climbed faster than the body was ready for.

There is also a safety ceiling built into the licence itself. The NHS semaglutide medicines page sets out the approved dosing pathway alongside important safety information, including when to seek urgent medical help. Pancreatitis, though uncommon, is one reason the MHRA monitors GLP-1 medicines closely; severe, persistent stomach pain that spreads to the back should always prompt a call to 111 or your GP rather than waiting it out.

Taking more than your prescribed dose, or sourcing semaglutide from a seller operating outside the licensed supply chain, removes the clinical guardrails entirely. That is not a small risk. Counterfeit weight-loss pens have been seized in large quantities across the UK, and some contained substances far more dangerous than the medicine they were imitating. If you want to understand what the highest dosage of semaglutide you can take looks like in practice, the answer is determined by your prescriber, reviewing your responses at each step, not by what happens to be available.

Is the highest dose always the most effective one for you?

Not necessarily. Some people achieve their weight-loss goals before reaching the maximum and stay on a lower maintenance dose. Others find that side effects at higher steps outweigh the additional benefit, and their prescriber stabilises them at a tolerated level. The dose ceiling matters less than whether the dose you are on is working safely for your body.

If you are considering private treatment and wondering how the process works, our treatment page sets out what a consultation with our prescribers involves, including how dose changes are reviewed. For people already on semaglutide elsewhere and thinking about their next step, our page on how Wegovy is prescribed privately covers the transfer process. And if you want a wider view of the options available, including how semaglutide compares to other licensed treatments, the weight-loss treatments overview is a good starting point.
