If you're weighing up the Wegovy tablet, one of the first things to get straight is the Wegovy tablet dose in the UK — how it starts, how it climbs, and how long before you reach the full maintenance dose. Oral semaglutide isn't a single-strength tablet you take forever; it's a step-by-step ladder, and understanding it makes the whole plan far less confusing.
This page is price and information only, not medical advice. The Wegovy pill is a prescription-only medicine, so a prescriber decides whether it suits you and which dose you should be on at any point.
Key takeaway: The Wegovy tablet builds up gradually — 1.5 mg, then 4 mg, then 9 mg, then a 25 mg maintenance dose — with at least a month at each level. That's roughly 12 weeks to reach the full dose, and the price usually rises as the dose goes up.
The four Wegovy tablet doses in the UK
Oral semaglutide (branded as the Wegovy pill by Novo Nordisk) is taken once a day as a tablet. There are four strengths on the standard escalation schedule:
- 1.5 mg — the starter dose, used to let your body adjust.
- 4 mg — the first step up.
- 9 mg — the second step up.
- 25 mg — the full maintenance dose most people aim for.
You stay on each dose for at least four weeks before moving up. The reason for climbing slowly is tolerability: starting straight on 25 mg would leave most people feeling very nauseous. The gradual approach gives your gut time to settle at each level.
How long does it take to reach the full Wegovy tablet dose?
Because there's a minimum of a month at 1.5 mg, 4 mg and 9 mg before you reach 25 mg, the fastest route to the maintenance dose is about three months — roughly 12 weeks.
That's a minimum, not a target. If side effects are troublesome at a given step, a prescriber may keep you there longer, or occasionally step back down. Some people also do well on a lower dose than 25 mg and never need to climb all the way. The ladder is a guide, not a race — the goal is the lowest dose that gives you good results with side effects you can live with.
What each dose is doing
The two lower doses (1.5 mg and 4 mg) are mostly about getting your body used to the medicine — you may notice some appetite change, but they aren't the doses that drive the biggest weight loss. The therapeutic work happens at 9 mg and especially 25 mg.
In the OASIS 4 trial (2025), people on the 25 mg maintenance dose lost about 13.6% of their body weight on average over 64 weeks, compared with about 2.2% on placebo. Among those who took it consistently, the average was closer to 16.6%, and around 30% lost at least 20% of their body weight. Those figures are for the full dose — which is why the escalation schedule matters. For more detail on how the pill compares with the jab, see our guide on the Wegovy pill vs Wegovy injection.
The empty-stomach rule applies at every dose
No matter which strength you're on, the routine is identical: take the tablet first thing after an overnight fast, with no more than about 120 ml of plain water, then wait 30 minutes before food, drink or other tablets. Food and extra water both cut absorption, so the habit is what makes the dose actually work. We cover this in full in how to take the Wegovy pill.
The good news is that the routine never changes as you climb the ladder — once it's a habit at 1.5 mg, it stays one all the way to 25 mg.
Wegovy tablet dose prices in the UK
Prices generally rise with the dose, so the monthly cost you pay at the start isn't the cost you'll pay at maintenance. Here's how a selection of GPhC-registered providers price each strength (per 4 weeks), based on our data last checked on 24 August 2026:
| Provider | 1.5 mg | 4 mg | 9 mg | 25 mg |
|---|---|---|---|---|
| Curate | £94.00 | £97.00 | £109.00 | £154.00 |
| Medicine Marketplace | £90.00 | £97.00 | £112.00 | £158.00 |
| Manchester Chemist | £94.99 | £99.99 | £114.99 | £159.99 |
| Live Well Weight Loss | £102.99 | £104.99 | £119.99 | £164.99 |
| The Weight Clinic | £115.00 (first month £80) | £130.00 | £145.00 | £190.00 |
| Chemist4U | £99.00 | £99.00 | £119.00 | £199.00 |
| Skin & Shape | £154.00 | £179.00 | £219.00 | £239.00 |
Across all providers, the 1.5 mg starter dose ranges from £86.99 to £154.00 — a £67.01 spread for the identical medicine. It's worth comparing the 25 mg price too, since that's what you'll be paying long term. You can see the full breakdown on our homepage price table or in our dedicated Wegovy pill price guide.
Our recommended provider is The Weight Clinic, which offers £35 off your first order with code NEWME (first month £80 on the starter dose), monthly video reviews as you move up the dose ladder, and a refund if the prescriber decides the medicine isn't suitable for you.
Side effects tend to peak around dose changes
The most common side effects — nausea, diarrhoea, constipation, vomiting and headache — are most likely in the first weeks and just after a dose increase. That's exactly why the escalation is slow. Rarer but serious risks include pancreatitis, gallstones and dehydration. If you experience side effects, you can report them through the MHRA Yellow Card scheme. For a week-by-week idea of what to expect, read our guide on Wegovy pill side effects.
Who can be prescribed the Wegovy tablet?
Typical eligibility is a BMI of 30 or above, or 27 and above with a weight-related condition. A prescriber checks your history and suitability before any dose is issued — there's no guaranteed approval, and there shouldn't be. Oral semaglutide was approved by the MHRA on 11 June 2026 as the UK's first oral GLP-1 weight-loss medicine and is currently available on private prescription only.

Frequently asked questions
How many Wegovy tablet doses are there in the UK?
Four: 1.5 mg, 4 mg, 9 mg and 25 mg. You start on 1.5 mg and step up one level at a time, spending at least a month at each dose before increasing.
How long until I reach the full 25 mg dose?
About three months — roughly 12 weeks — assuming you spend the minimum four weeks at 1.5 mg, 4 mg and 9 mg. Your prescriber may keep you on a step longer if side effects are difficult.
Do I have to reach 25 mg?
Not necessarily. The 25 mg maintenance dose gives the strongest average results, but some people do well on a lower dose. Your prescriber aims for the lowest dose that works well for you with tolerable side effects.
Why does the price change as the dose goes up?
Most providers charge more for higher strengths, so the amount you pay at 1.5 mg is usually lower than at 25 mg. It's worth checking the maintenance-dose price, not just the starter price, before choosing a provider.
Is the empty-stomach routine different at higher doses?
No. Whatever strength you're on, you take the tablet after an overnight fast with up to 120 ml of plain water and wait 30 minutes before eating. The routine stays identical all the way up the ladder.
Is the Wegovy tablet available on the NHS?
As of mid-2026 it is available only via private prescription. NHS funding would need a separate NICE appraisal.
