What the four-step schedule looks like from 1.5mg to 25mg
If you are trying to picture how the dose changes over time, here is the shape of it. Wegovy tablets begin at 1.5mg once daily. After at least a month, the prescriber may move you to 4mg, then 9mg, then the 25mg maintenance dose, keeping you on each rung for a minimum of four weeks before the next increase.
Why so gradual? The early doses are not really there to shift weight. Their job is to let your digestion adjust to a GLP-1 medicine, which reduces the nausea and other stomach upset that tend to be worst when treatment starts or steps up. Think of the first few weeks as your system getting used to the idea, with the real appetite effect arriving as the dose climbs.
People already established on the 2.4mg weekly Wegovy injection can, subject to clinical assessment, move straight to the 25mg tablet rather than starting the ladder again. That is a decision for a prescriber, not something to attempt on your own. The exact dosing detail sits in the product's Patient Information Leaflet and SmPC, and our oral semaglutide dosage chart lays the same schedule out visually if that helps you follow it.
How the tablet is meant to be taken, and why timing matters so much
The dose only works if the tablet is taken correctly, and oral semaglutide is fussier about this than most medicines. It goes down first thing in the morning, on an empty stomach, with no more than a small sip of plain water. Then you wait.
That wait is at least 30 minutes before anything else passes your lips: no coffee, no breakfast, no other tablets. The absorption enhancer built into the tablet needs a clear stomach to get the semaglutide across the gut wall, and coffee or food arriving too soon can blunt how much of the dose you actually absorb. Swallow it whole, do not split or crush it.
For a lot of people this simply becomes part of the morning: tablet first, then the kettle goes on. It is worth building the habit deliberately, because a rushed cup of tea can quietly undercut the dose you have been prescribed. Unlike the injections, the tablets need no fridge, which makes them easier to travel with. If you want the day-to-day mechanics spelled out further, our page on the daily semaglutide tablet dose covers the routine in more detail.
What the trial evidence says the dose can achieve
Numbers help set expectations honestly. In the OASIS 4 trial, which enrolled 307 adults with obesity or overweight plus at least one weight-related condition and ran for 64 weeks alongside lifestyle changes, participants taking oral semaglutide lost around 13.6% of their body weight on average, against roughly 2.4% on placebo.
Among the people who stayed fully adherent to the treatment across the trial, the average was higher, at about 17%. That fuller figure is only meaningful with its caveat attached, because it reflects those who kept to the schedule and the strict morning routine throughout. Both figures come from Novo Nordisk's UK data behind the June 2026 approval.
The honest read is that the 25mg maintenance dose does most of the work, and results depend heavily on taking the tablet as intended and pairing it with diet and activity. No one should expect the lower starter doses to move the scale much on their own. If you are curious how the tablet compares with the higher rungs people ask about, our page on the 7mg semaglutide tablet query untangles which strengths belong to which product and licence.
Rybelsus versus Wegovy tablets: two very different dose ladders
This is the mix-up that trips people up most, so it is worth being blunt. Both Rybelsus and Wegovy tablets are oral semaglutide, but they are different products with different licences and completely different dose ranges.
Rybelsus comes in 3mg, 7mg and 14mg strengths and is licensed for type 2 diabetes. Those numbers are not steps on the weight-loss schedule, and you should never treat a 3mg, 7mg or 14mg tablet as a rung of the Wegovy ladder. The Wegovy weight-loss tablet uses 1.5mg, 4mg, 9mg and 25mg, and nothing else.
If your search started with a Rybelsus strength, it is easy to see how the confusion arises when a single molecule wears two brand names. Our explainer on what the Rybelsus 3mg tablet is used for keeps the distinction clear, and if weight management is what you are actually after, the Wegovy tablet schedule above is the relevant one. When in doubt, a prescriber will confirm which product fits your goal.
Who the oral dose is licensed for, and who it is not for
Wegovy tablets are licensed in the UK for adults with a BMI of 30 or above, or 27 to 29.9 with at least one weight-related condition such as high blood pressure, high cholesterol, prediabetes or obstructive sleep apnoea, taken alongside a reduced-calorie diet and more activity. Lower BMI thresholds can apply for some ethnic backgrounds under UK guidance; you can read the full detail on our page about accessing semaglutide tablets in the UK.
Some people are not suitable regardless of BMI. The tablets are not used in pregnancy, are not recommended while breastfeeding, and are not for anyone trying to conceive; they are also not licensed for under-18s. A history of pancreatitis, medullary thyroid cancer or certain gut conditions needs to be discussed openly before any dose is prescribed.
BMI on its own never settles it. A prescriber weighs your medical history, current medicines and goals against the licence, which is why the number is a starting point rather than a verdict. If you are weighing the tablet against the once-weekly pen, our overview of semaglutide tablets sets the two side by side.
The side effects that shape how the dose is stepped up
The gradual dose ladder exists largely because of how GLP-1 medicines feel at first. The most common effects are digestive: nausea, an unsettled stomach, diarrhoea or constipation, indigestion and tiredness. In the OASIS 4 trial these were reported by around 74% of people on oral semaglutide, most often mild to moderate, and they tended to ease as the body adjusted.
That is exactly why each dose is held for at least a month. A slower climb gives your gut time to settle before the next increase, which is more comfortable than rushing to 25mg. If side effects are troublesome, a prescriber may hold a dose for longer rather than push on.
A rarer but serious signal to know about is acute pancreatitis. In January 2026 the MHRA reminded prescribers and patients that severe, persistent stomach pain that can spread to the back, with or without vomiting, needs urgent medical attention. You can report any suspected side effect through the MHRA Yellow Card scheme, and the patient-level detail is set out on the NHS medicines page for semaglutide. None of this should alarm you into avoiding treatment, but knowing the warning signs is part of taking any prescription medicine sensibly.
Can you get the oral dose on the NHS, and what it costs privately
As of summer 2026 the Wegovy weight-loss tablet is not available on the NHS. A NICE appraisal would need to conclude first, and until then the tablets are a private prescription option only. The injectable versions of semaglutide reach the NHS through specialist weight management services under strict, phased criteria, which you can read about on NHS England's weight-management injections guidance.
On private cost, headline figures rarely tell the whole story. Prices vary by provider and often exclude the consultation, prescription, delivery and any follow-up support, so a low sticker can hide extras. With nume, one transparent price covers your free consultation, the prescription, the medicine, free next-working-day tracked delivery and aftercare seven days a week, with no subscription and every repeat clinically re-reviewed.
We are not the cheapest, and we do not pretend to be. For a prescription medicine, price is the wrong test anyway; genuine supply, a real prescriber and proper aftercare are what keep you safe. Current treatment pricing sits on our treatment page. If you are still deciding whether the tablet or an injection suits you, that is precisely what a consultation is for.
Speak to our prescribers if you want the oral dose assessed for your situation. Start your free consultation and a real clinician, not a bot, reads your answers and confirms whether the tablet schedule is right for you.
