Wegovy pill vs injection in the UK

On 11 June 2026 the MHRA approved the first daily GLP-1 tablet for weight management in the UK: semaglutide 25mg, sold as the Wegovy pill. Here is how the tablet and the once-weekly injection differ in practice, in evidence and in price. Information, not medical advice; format choice belongs with you and a prescriber.

This page is information, not medical advice. It never tells you which medicine, dose or format is right for you: those decisions sit with you and a qualified prescriber. Spotted an error? Tell us and we'll fix it fast.

The regulatory position

The MHRA licensed the semaglutide tablet on 11 June 2026 for adults with a BMI of 30 or more, or from 27 with at least one weight-related condition, alongside diet and exercise: the same eligibility frame as the injection. It is a prescription-only medicine and is not currently available on the NHS pending NICE evaluation, so access today is through regulated private providers.

Daily tablet vs weekly injection

The injection is taken once a week, any time of day, with doses stepping from 0.25mg up to 2.4mg. The tablet is taken once every day, and timing matters: whole, on an empty stomach after fasting at least 8 hours, with a sip of water, then nothing to eat or drink for at least 30 minutes. Tablet doses step from 1.5mg through 4mg and 9mg to the 25mg maintenance dose, with at least a month between increases.

Practical differences worth weighing

Needles: the tablet suits people who cannot or prefer not to inject.
Routine: weekly and flexible versus daily with strict fasting rules. Which is easier depends entirely on your life, and adherence drives results more than format does.
Storage and travel: injection pens need cold-chain care before first use; tablets do not, which simplifies travel.
Supply form: the tablet comes as a 28-day pack; the injection as a multi-dose pen.
Side effects: the most common with both are gastrointestinal (nausea, diarrhoea, constipation, vomiting), typically during dose escalation. Full safety information is in the patient information leaflet; suspected side effects go to the MHRA Yellow Card scheme.

What the evidence shows

In OASIS 4 (published in the New England Journal of Medicine, 2025), the 25mg daily tablet produced an average weight reduction of about 14% versus 2% with placebo over 64 weeks of treatment, with 30% of participants losing a fifth or more of their body weight. The investigators noted this is comparable to the 2.4mg weekly injection's result in STEP 1 (14.9% over 68 weeks), though the two formats have not been compared head-to-head in a single trial, so treat cross-trial comparisons cautiously.

Wegovy pill vs injection questions

Is the Wegovy pill as effective as the injection?

The tablet and the injection have not been compared directly in one trial, so exact equivalence cannot be claimed. In OASIS 4 the 25mg daily tablet produced an average weight reduction of about 14% versus 2% with placebo over 64 weeks of treatment, which the investigators described as comparable to what the 2.4mg weekly injection achieved in its own trial (STEP 1, 14.9%). Individual responses vary; a prescriber can put these figures in context for you.

Is the Wegovy pill available on the NHS?

Not at the time of writing. The MHRA approved the tablet on 11 June 2026 for private prescription; NHS availability depends on a separate NICE evaluation. Regulated private providers are beginning to stock it, and our Wegovy pill comparison tracks who lists it and at what price.

Why do the food and water rules for the tablet matter?

Semaglutide is a peptide that the stomach breaks down easily, so the tablet must be taken on an empty stomach after an overnight fast, with only a sip of water, and nothing to eat or drink for at least 30 minutes afterwards. Skipping those rules can substantially reduce how much of the medicine is absorbed, which is one of the practical differences a prescriber will talk through.
