What's the maximum dose of semaglutide for weight loss?

Why does semaglutide start so low if the maximum is 7.2mg?

The gap between the 0.25mg starting dose and the 7.2mg ceiling isn't a shortcoming in the medicine, it's deliberate design. Semaglutide slows gastric emptying and acts on appetite-regulating receptors in the brain, and those effects can cause nausea, vomiting or stomach discomfort when the body encounters them suddenly at full strength. Starting low gives your system time to adjust before the dose does any meaningful therapeutic work.

Each step in the titration ladder (0.25mg, 0.5mg, 1.0mg, 1.7mg, and then 2.4mg) lasts a minimum of four weeks. Your prescriber reviews whether side effects are manageable before the next increase. Rushing the schedule doesn't improve results; it mainly increases the chance of GI side effects severe enough to interrupt treatment altogether.

The NHS patient-level guidance on semaglutide sets out this titration pathway clearly, and a prescriber will always weigh up your individual tolerance before recommending any dose change. One practical habit worth building: check the strength printed on your pen against your prescription before every injection. It takes under a minute and catches errors before they matter.

What changed when 7.2mg was approved, and who does it apply to?

Until early 2026, the highest licensed dose of Wegovy was 2.4mg weekly, and that remained the maintenance target for most patients. On 14 April 2026, the MHRA approved a dedicated single-dose 7.2mg Wegovy pen, a pre-set weekly injection with an auto-dosing mechanism and a built-in covered needle that locks after use. This made the UK one of the first countries to have access to the higher dose in this format.

The 7.2mg licence applies specifically to adults with a BMI of 30 or above. It is not approved for people using Wegovy under the lower BMI threshold (those with a weight-related condition at 27–29.9), and it does not apply to the cardiovascular indication for semaglutide. If you are currently on 2.4mg and wondering whether advancing further makes clinical sense for you, that question belongs in a consultation with your prescriber, not in a dose you select independently.

Trial data at this higher dose reported average weight loss of around 20.7% over 72 weeks, narrowing the gap that had previously existed between Wegovy and tirzepatide in head-to-head comparisons. You can read more about how the two medicines compare on our Wegovy overview page.

Does reaching the maximum dose mean treatment is working better?

Not necessarily. Some people achieve strong results at 1.7mg or 2.4mg and have little reason to push further. If you want a fuller picture of what the maximum dose of semaglutide involves and when it becomes relevant, that page explains the clinical reasoning behind the ceiling. The maximum dose exists as an option for those whose weight loss has plateaued and who are tolerating the medicine well, not as a destination everyone is expected to reach.

NICE's guidance on semaglutide for weight loss (TA875) recommends reviewing whether to continue treatment if less than 5% weight loss has occurred after six months at the maintenance dose. That review point matters regardless of whether the patient is at 2.4mg or 7.2mg. For a clear breakdown of what the maximum dose of semaglutide is and how prescribers decide whether it applies to you, our dedicated page covers the key criteria in plain terms.

The question of what's considered a clinically appropriate maintenance dose depends on response, tolerability and the prescriber's overall assessment. Our page on what counts as a maintenance dose of Wegovy covers this in more detail. For context on how Wegovy fits into the broader range of weight-loss treatment options available privately in the UK, that page is a useful starting point too.

What about oral semaglutide, does it have a different maximum?

Yes. Wegovy tablets (the oral formulation of semaglutide approved by the MHRA on 11 June 2026) follow a completely separate dosing ladder: 1.5mg → 4mg → 9mg → 25mg daily, with a minimum of one month at each level. The 25mg daily tablet is the oral maximum, and these strengths are not the same as the Rybelsus diabetes tablet strengths (3mg, 7mg and 14mg), that's a distinction worth being clear on.

The oral route removes the need for injections, which some people find easier to sustain, though the absorption requirements are stricter: the tablet must be taken first thing in the morning on an empty stomach with a small amount of plain water, waiting at least 30 minutes before food or other medicines. Room-temperature storage means no fridge is needed, which is a genuine practical advantage for travel.

If you're weighing up the injection against the tablet (or wondering which dose schedule suits your lifestyle) that's exactly the kind of conversation our prescribers have during a consultation. You can also explore how Wegovy doses work across both formulations before you book.
