Wegovy Pill vs Injection: Which Form of Semaglutide Suits You? (November 2026)

01 · Which suits you

Wegovy pill or injection: which suits you?

• The injection may suit you if you are happy to inject once a week and want the simplest routine, with no rules about food or water.
• The tablet may suit you if you would rather not inject and can take a tablet first thing every morning, then wait 30 minutes before eating or drinking.

Both are licensed for weight management in adults with a BMI of 30 or above, or 27 to under 30 with at least one weight-related condition, alongside a reduced-calorie diet and more physical activity.¹² A prescriber helps you decide which form is right for you.

02 · Support

Getting help

Wegovy tablets and injections are prescription-only medicines, supplied only after an online consultation reviewed by a GPhC-registered prescriber. This page is information, not a substitute for medical advice. Always follow the leaflet that comes with your medicine.

03 · Same medicine, different form

Same medicine, different form

Wegovy injections and Wegovy tablets both contain semaglutide, which acts on the GLP-1 receptor to reduce appetite and slow stomach emptying.¹² The tablet was approved by the MHRA in June 2026 as the first GLP-1 tablet for weight loss in the UK.²

Because a tablet has to survive the stomach and be absorbed from it, the tablet doses are much higher in milligrams than the injection doses. The 25mg tablet is not "ten times stronger" than the 2.4mg injection; the numbers simply reflect how much medicine is needed for each route.

04 · How to take the tablet

How to take Wegovy tablets

The tablet must be taken on an empty stomach after fasting for at least 8 hours, swallowed whole with a sip of water (up to half a glass, about 120ml), and you then wait at least 30 minutes before eating, drinking or taking other tablets.² Most people take it first thing in the morning.

Treatment starts at 1.5mg once daily and steps up to 4mg, 9mg and then the 25mg maintenance dose, with at least one month at each dose; the dose can stay at an earlier step if needed.² If a dose is missed, skip it and take the next tablet the following day.

05 · How to take the injection

How to take the Wegovy injection

The injection is given under the skin once a week, on the same day each week. The dose steps up after 4 weeks on each of 0.25mg, 0.5mg, 1mg and 1.7mg, so the 2.4mg maintenance dose starts from week 17.¹ There are no rules about food or water. Each pen holds four weekly doses.

06 · Results compared

Wegovy pill vs injection: results

In STEP 1, adults on semaglutide 2.4mg injections lost on average 14.9% of body weight over 68 weeks, compared with 2.4% on placebo.³ In the OASIS 4 trial, adults taking semaglutide 25mg tablets for 64 weeks lost on average 13.6% of their body weight, compared with 2.2% on placebo.⁴

The trials were separate and not designed to compare the two directly, so small differences should not be over-read. For most people, the choice comes down to which routine they can keep up.

07 · Side effects compared

Wegovy pill vs injection: side effects

Side effects are similar because the medicine is the same. The most common are digestive: nausea, diarrhoea, vomiting, constipation, indigestion and stomach pain, most likely in the first weeks and after each dose increase.¹² In STEP 1, gastrointestinal side effects were reported by 74.2% of people on semaglutide 2.4mg injections, compared with 47.9% on placebo.³

Seek urgent medical help for severe, persistent stomach pain that may spread to your back, pain in the upper right abdomen with fever or yellowing of the skin or eyes, or signs of a severe allergic reaction.

08 · Switching between them

Switching from the Wegovy injection to the pill

People on the 2.4mg weekly Wegovy injection can move to the 25mg tablet, starting one week after their last injection.² If you are on a lower injection dose, or want to move the other way, the prescriber decides when to switch and which dose to start on. Never take the tablet and the injection together.
