The Wegovy pill dosage steps are four once-daily doses: 1.5 mg for the first month, then 4 mg, then 9 mg, and finally the 25 mg maintenance dose, with at least a month on each of the first three. At the fastest pace the UK licence allows, 25 mg starts in month four. At every step it is one tablet a day, taken the same careful way.
This is information only, not medical advice. The Wegovy pill (oral semaglutide) is a prescription-only medicine, licensed by the MHRA on 11 June 2026, and a qualified prescriber decides whether it suits you and how quickly your dose rises.
What are the Wegovy pill dosage steps?
The UK patient leaflet, revised in June 2026, sets the schedule out month by month:
- Month 1: 1.5 mg once daily (the starting dose).
- Month 2: 4 mg once daily.
- Month 3: 9 mg once daily.
- Month 4 onwards: 25 mg once daily (the maintenance dose).
The prescriber-facing Summary of Product Characteristics (SmPC) gives the same ladder with two qualifiers that matter: a minimum of one month at each dose level, and the option to keep the dose at the previous level if needed. The US label counts in 30-day blocks, with 25 mg from day 91 (see our dosage page).
Why does the Wegovy pill start at such a low dose?
The slow start is about tolerability. The US label says the schedule is there to reduce the risk of gastrointestinal side effects, which the UK SmPC says were reported most often during dose escalation. In OASIS 4, the 64-week trial of the 25 mg tablet, gastrointestinal adverse events affected 74.0% of people on the tablet versus 42.2% on placebo. The SmPC lists nausea at 46.6% (18.6% on placebo), vomiting 30.9% (5.9%) and diarrhoea 17.6% (8.8%), mostly mild to moderate and short-lived; constipation, at 20.1% (9.8%), tended to last longer.
Our side effects page has the full list. The tablet carries the black triangle (▼) for additional monitoring, and suspected side effects can be reported through the MHRA Yellow Card scheme.
Can you stay on a step for longer, or move up faster?
Staying longer: yes, if your prescriber agrees. One month per step is a minimum, and the UK SmPC allows the dose to stay at the previous level if needed. Vomiting and diarrhoea can cause dehydration, which the SmPC says can rarely worsen kidney function, so report persistent symptoms rather than pushing on.
Moving faster: no. Reaching 25 mg in under three months would fall outside the UK licence. Any change of pace, including holding or stepping back a dose, is your prescriber's decision.
Why is it always one tablet a day?
The UK SmPC says oral semaglutide is always used as one tablet per day, and more than one tablet should not be taken to get the effect of a higher dose.
Never combine lower strengths or take an extra tablet to catch up. If you take more than you should, the leaflet says to talk to your doctor straight away.
To help catch a mix-up, the leaflet describes the 1.5 mg, 4 mg and 9 mg tablets as round and the 25 mg tablet as oval, each marked with its strength.
Same numbers, different medicine: Rybelsus
Rybelsus, the oral semaglutide licensed for type 2 diabetes, has a newer 1.5 mg, 4 mg and 9 mg formulation replacing its 3 mg, 7 mg and 14 mg tablets; a UK letter to healthcare professionals dated 4 August 2025 warned of mix-ups during the changeover. It has its own licence and schedule, so its tablets are not steps on the Wegovy ladder.
Does the way you take it change at each step?
No. According to the UK SmPC, at every dose you take the tablet on an empty stomach after fasting for at least 8 hours, swallow it whole with a sip of water (up to half a glass, 120 ml), then wait at least 30 minutes before eating, drinking or taking other oral medicines. Waiting less than 30 minutes reduces absorption.
That matters because so little gets in: the SmPC estimates oral bioavailability at about 1% to 2%, with blood levels varying more between people than on the injection. With a half-life of about a week, steady levels take 4 to 5 weeks of daily dosing to build, roughly the length of one step. Our empty-stomach rule article explains the chemistry.
What if you miss a dose part-way through the steps?
The leaflet says to skip the missed dose and just take your normal dose the next day; the one-tablet rule means never taking two to make up. It gives no separate rule for a longer gap, so after several missed days ask your prescriber or pharmacist how to carry on, and do not stop treatment without talking to your doctor.
How does switching from Wegovy injections to the pill work?
People on the 2.4 mg weekly injection do not have to start again at 1.5 mg. At approval the MHRA said they can be transitioned straight to the 25 mg once-daily tablet, and the UK SmPC says tablets can start one week after the last injection, while cautioning that the effect of switching cannot easily be predicted because absorption from the tablet varies more. On a lower injection dose, ask your prescriber. See our pill vs injection comparison.
What did the OASIS 4 trial show?
OASIS 4, published in the New England Journal of Medicine in 2025, randomised 307 adults without diabetes to the tablet or placebo. The US label says the dose was escalated to 25 mg over 12 weeks, then held for 52 weeks. At week 64, average body weight had fallen by 13.6% on oral semaglutide versus 2.2% on placebo, counting everyone whether or not they stayed on treatment. For the mechanism, see how the Wegovy pill works.
Can you get the Wegovy pill on the NHS?
The MHRA approved the tablet on 11 June 2026 for adults with a BMI of 30 or above, or 27 to 30 with at least one weight-related condition. It said the tablet was not available on the NHS, with NHS use to follow processes including a NICE evaluation. As of September 2026, NICE's project page for an appraisal of oral semaglutide for managing overweight and obesity (ID6188) still shows it as discontinued, dated 12 May 2025, after the company said it would not provide evidence. In practice the tablet is prescribed privately: prices vary between regulated providers, so compare carefully and use only a GPhC-registered pharmacy or CQC-regulated clinic. Avoid anyone selling semaglutide without a prescription or offering unlicensed "compounded" versions. See our FAQ.
Frequently asked questions
How long does it take to reach the 25 mg Wegovy pill dose?
At least three months: 1.5 mg in month one, 4 mg in month two, 9 mg in month three and 25 mg from month four. It takes longer if your prescriber holds you on a step.
Can I take two 9 mg tablets instead of one 25 mg tablet?
No. The UK product information says oral semaglutide is taken as one tablet a day, and more than one tablet should not be taken to get the effect of a higher dose.
What should I do if I miss a dose of the Wegovy pill?
Skip it and take your normal dose the next day, as the patient leaflet advises; do not double up. After several missed days, ask your prescriber or pharmacist.
Do I start at 1.5 mg if I'm switching from Wegovy injections?
Not if you are on the 2.4 mg weekly injection: the UK SmPC says the 25 mg tablet can start one week after your last injection. On any other injection dose, ask your prescriber.
Is the dose different for older people or those with kidney or liver problems?
According to the UK SmPC, no dose change is needed for age or for mild or moderate kidney or liver impairment, though liver impairment calls for caution. It is not recommended if either is severe.
